Modbus Batch Read Multiple Registers Groups

Issue What is the maximum number of registers that can be read/written using the multiple read/write function codes in Modbus Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Modbus Register Groups Cause When deciding how to group registers using a Modbus Register Group, what are the maximum number of registers that can be grouped. Resolution There is a limit to the number of packets that can be polled in a single packet, however, if this number is exceeded then two or more polls will be made (blocks).  The nominal Read multiple registers maximum is 125 16 bit registers (250 8-bit bytes, so the register count will vary for 32 and 64bit polls).  The Register Group Properties Tab shows the number of blocks being polled. The Modbus register grouping function has a direct effect on system performance. A poorly grouped device can easily increase the overall poll time as points, or blocks, in each Modbus network are polled sequentially.  See the section "Batch Read Function" in the EcoStruxure Building Operation Technical Reference Guide for full details. Note: Multiple group writes are not possible and are not controlled via Modbus Register Groups.

Modbus points polling mechanism

Issue How and when are Modbus points polled? Product Line EcoStruxure Building Operation Environment Building Operations Enterprise Server Building Operation Automation Server Cause Need to understand the Modbus poll mechanism Resolution Consult the 'Modbus Deep Technical Reference' chapter of EcoStruxure Technical Reference Guide Or use WebHelp to find information on the Modbus Poll Manager, which manages all polling of the points/data and devices, and the Poll List which contains all the current subscriptions (eg. data being referenced within Programs, Listviews, Graphics, Logging, etc) These mechanisms isolate the Modbus Polling from programs and graphics. Note: For each network, the poll manager operates with a poll list and a poll task. If a Modbus Object value is only required for logging purposes, then the  "Requested poll interval" is set to a high number (typically 2,147,483,647 ms) This means the object values are not currently being polled. When the time arrives for the log value to be collected, the "Requested poll interval" is set to 1000ms, until the value is collected, at which point it reverts to this higher number.

Using Modbus Register Group to batch read registers

Issue Modbus Register Groups feature can overcome some Modbus communication problems. It has been seen before where the Modbus controller falls offline for a few seconds then comes back online. This cycle will repeat every few seconds. When register groups are not used, there may also be issues with the amount of time it takes for a Modbus points to update. Product Line EcoStruxure Building Operation Environment Building Operation Workstation Building Operation Enterprise Server Building Operation Automation Server Premium (AS-P) Building Operation Automation Server Bundled (AS-B) Cause In a normal Modbus network, a Modbus polling device obtains data from a polled device by sending a query message to the device and then waiting for the response message that contains the requested value from the selected register. If data from another register is required, the polling device sends out a new query message and awaits the response message. This process is repeated until all subscribed points values have been read. The Modbus Register Groups are a batch read function to poll Modbus devices. Instead of reading each register individually, the batch read function reads registers in manually created groups. When all registers in a group have been read, the response message returns subscribed register values for the whole group. Register grouping provides a dramatic saving in the time taken to poll your devices. For more guidance and tips on this topic, see Section "Batch Read Function" in the EcoStruxure Building Operation Technical Reference Guide.  Note: When viewing a graphic containing Modbus values, those values will update at the same interval as their Modbus register group. Resolution When grouping Modbus points, it is important to keep in mind some of the following points. Try to ensure that as many Modbus points as possible are contained in as few groups as possible. This will reduce the overall time it takes the Enterprise Server or Automation Server to read all the subscribed points in each Modbus device. Network performance can be enhanced by choosing the method of grouping that is most suitable for each device in the Modbus network.  Network performance can be enhanced by selecting a different default poll time for each register group. Network performance can also be enhanced by grouping points that have the same or similar polls. Start with higher group poll times to ensure a stable system before reducing the poll time. Make sure to delete Modbus points out of a register group individually before deleting the group. If this is not done, it can cause system delays. See article Modbus Batch Read Multiple Registers Groups Creating a Modbus Register Group In Workstation, in the System Tree pane, right-click on a Modbus device and select New Object (1).  In the create object window select Modbus Register Group (2), provide a name and select Create (3). Now that the group has been created, existing Modbus points can be dragged and dropped into the group. New Modbus points can also be created in the group.  Right-click on the Modbus Register Group and select New Object (1).  In the create object window expand Modbus Point (2), select a point type (3), provide a name and select Create (4).

Quickly delete 100,000 alarms and a lot of old trend data

Issue My Server has a 100,000 alarms and a lot of old trend data.  How can I delete them quickly? Product Line TAC IA Series Environment I/A Series R2 Niagara Cause The APP folder under the station holds all alarm and trended data.  When this folder gets too big, i.e. >500 MB the Server functionality can slow down while working with this large database file. Resolution Stop the Server station Rename the existing APP folder to something other than APP Restart the Server station.  When the Server station restarts it will check for the presence of a folder called APP and when none is found it will create a new one and use that one to archive alarms and trend data.

Having a mix of Cyberstation versions on the same system

Issue Is it possible to have different software versions on the Cyberstation workstations? Product Line Andover Continuum Environment Continuum Cyberstation Cause When adding an extra workstation to a system does it have to match the version of existing workstations? Resolution All workstations on the same system must be exactly the same version including any service packs. This also includes Web Client servers. You will either need to install the same version as the rest of the system or upgrade all other workstations to the latest version, although this may need an upgrade of the security keys.

Viconics VT7600x1000x exceeding the set 3 Cool Cycles Per Hour (CPH)

Issue Tested the Viconics VT7600x1000x for Cool CPH set to 3.  Manually heated the thermostat and let it cool to cycle the cool stages and it cycled on and off 7 times before stopping the test.  According to the documentation it should have stopped after 3 on/off cycles. Product Line Field Devices Environment SSL SE7000 Cause Cooling/heating has to be within 15-85% of the proportional band. Resolution With the Viconics VT7600x1000x series products, the CPH only works when the cooling/heating demand is within 15 to 85% of the proportional band. The thermostat has a 2 degree proportional band (fixed) so at a setpoint of 72 and CPH of 3 (cooling CPH adjustable 3-4), if the temperature stays between 72.3 and 73.7 the CPH is at 3. Outside of that band the cooling/heating is allowed to cycle as often as needed.

Can J Bus devices be used with an Automation Server?

Issue Will J-Bus operate with Modbus RTU devices on the same bus? Product Line EcoStruxure Building Operation  Environment Building Operation Automation Server Building Operation Automation Server Premium Building Operation Automation Server Bundled Cause Compatibility of J Bus required. Resolution The J Bus protocol is supported by the Autimation Server, it runs on an RS485 network and uses a subset of the Modbus RTU protocol function codes. The J Bus devices addressing usually has an offset of 1 compared to the Modbus RTU standard, to apply this offset select "J-Bus Mode" = Yes in the Modbus Master Network Properties.   Verify that the devices to be used have a standard RS485 electrical connection and do not require any special electrical biasing, also ensure that all units connected on the bus have a unique ID/ address number. If this is the case then you should be able to connect both Modbus RTU and J Bus devices on the same Automation Server port connection but in the Modbus Master Network select the J Bus Mode setting to No. In J-Bus mode, the Automation Server will automatically reduce the polled register addresses by one, so if the AS is set to Modbus mode, you may need to manually set the register addresses of any J-Bus devices by minus one. With J Bus as with Modbus sometimes the point addressing needs to be offset by +1 or -1, but check with the 3rd party device supplier/ documentation to determine its specific point addressing requirements.

Setting default BACnet priority levels in EcoStruxure Building Operation

Issue Setting the default BACnet priority levels for different applications avoids priority conflicts by normalizing which priority gets used for a specific action or within a specific application Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server Building Operation Automation Server Premium Building Operation Automation Server Bundled Building Operation Edge Server - Standard Cause Different EcoStruxure applications may act upon BACnet objects utilizing different BACnet priority levels. This may cause confusion and can keep the system from operating as expected. Resolution BACnet objects created with EBO (1.4 and higher) will have a default BACnet Priority of 16 unless specified otherwise. The default BACnet Priority can be changed to the customer's needs.   As a best practice, define the Default priority level prior to configuring the system. In addition, consider maintaining the same default priority level for multiple active systems at your site. For example, configure the same default priority level for the EcoStruxure Building Operation and fire protection system. In a multi-server system, you can only configure the Default priority level from the Interface Manager of the Enterprise Server. If you set a new priority level, the system propagates the change to the other automation servers in the network. Refer to: Default Priority Level (se.com) and Configuring the Default Priority Level (se.com)

Access Expert exception error adding a downstream device to an SSC

  Issue When attempting to add a downstream device to an SSC the error "exception of type \'Feenics.Keep.DomainModel.KeepException\' was thrown" Product Line EcoStruxure Access Expert Environment  Access Expert V3 Cause The SSC has a limitation of 32 downstream devices no matter what port(s) are being used either RS485 or virtual.  Resolution The SSC specification data sheet indicates the SSC can manage up to 64 downstream devices. However, R&D has corrected our understanding of this limitation which is only 32 downstream devices. Attempting to add a 33rd downstream device will result in the   \'Feenics.Keep.DomainModel.KeepException\' error. An additional SSC or Mercury upstream controller will be necessary to commission greater than 32  downstream devices.   From R&D: "The SSC can support a Total of 32 downstream devices no matter what port they are connected to either RS485 or Virtual. The SSC can also support 64 doors total."

The procedure to follow for upgrading or downgrading the I/A Series G3 software in an I/A Series ENC

Issue What is the procedure for upgrading the I/A Series G3 software in an I/A Series ENC? Product Line TAC IA Series Environment I/A Series G3 Workbench software on computer (both the old version and new version need to be installed on the computer) I/A Series G3 ENC-520 or ENC-410 Cause Need to upgrade the software that is installed in the ENC. Resolution With the old version of Workbench running on the computer, backup the station running in the ENC.  All required graphic files, etc., stored in the ENC should also be backed up.  Note the station folder name for use in step 5, below. Verify that the license in the ENC is compatible with the new release to be installed. If not, use the License Manager (under the Platform) to install an updated license. If the correct version of the license is not currently available, it must be obtained and installed prior to beginning step 6, below. If the new release of the I/A Series G3 software has not already been installed on the computer, install it now. Verify that the Workbench computer has a license that is version compatible with the new release of the I/A Series software to be installed.  If the license is not version compatible, acquire a new license for the Workbench computer before continuing. Copy the entire named station folder (used in step 1) from the old release Stations folder to the new release Stations folder.  See NOTE below regarding the installation of a version downgrade. Run the "Install Platform Daemon" command from the Windows Start Menu folder for the new version of the software. Open the Workbench in the new version of the I/A Series G3 software and connect to the platform of the ENC to be upgraded. From the Platform menu, open the License Manager and verify that the ENC license has been updated to allow use with the new version of the I/A Series G3 software. Right-Click on the ENC platform in the Workbench tree and select Commissioning Wizard. Complete the commissioning process as documented in the Niagara AX Install and Startup Guide . On the first screen, select the operations to be performed.  The required minimum operations will normally be checked and shown in grey.  The "Install a station..." option needs to be checked if not already checked. Click [Next] to begin the commissioning process.  Continue through the various steps, as required.   When prompted, select the station copied in step 5. When prompted, verify that all required modules are available and are selected for installation. Allow the commissioning process to complete, following the prompts as required. The upgrade is now complete.  Start the station as required. NOTE: Do not use the process to directly downgrade the version of software installed in an ENC.  You must use the Platform "Distribution File Installer" to install the appropriate clean distribution (from the cleanDist folder under the software version to be installed.  Typically, only one clean distribution file will be available to be installed.  Select that file then click the [-> Install] button to downgrade the ENC software.  This process needs to be done as noted in step 5, above, after backing up the station but before beginning the commissioning of the device with the older I/A Series G3 software version.

Trend log limitations in SmartX IP Controllers

Issue What is the maximum number of trend logs in a SmartX IP Controller? What is the maximum number of trend log records in a SmartX IP Controller? Product Line EcoStruxure Building Operation Environment Building Operation Multi-purpose Controller Cause SmartX IP controller free object system memory is shared between objects and data in your application. There are no specific limits on the number of objects and/or trend logs that you can create. Several factors impact memory consumption: Every object added consumes a fixed amount of memory Memory is shared between objects and data. Adjustments to description fields or trend log buffer sizes will also impact the amount of memory consumed. Different controllers have different amounts of memory to start from. RPC controllers have roughly half of the memory of an MPC. Changes to EBO 3.X will also change the memory consumption, so upgrading your system may skew the memory consumption larger than it was in previous versions. Resolution After adding trend logs to the device consult the Free object system memory entry in the device report since this will help determine how much free memory is available. Trend log buffers are pre-allocated on creation of the trend object. The other place to find how much free memory the device have is in the device property page. This value can be put in a watch window, trended, or even bound to a low-limit alarm.     If the amount of free memory drops below 50 Kbytes, that is critically low available memory. A better target is to try to preserve 50% of available memory. Based on empirical testing, estimates of memory available inside a blank controller are: MP-C: 1890 Kbytes MP-V: 1780 Kbytes RP-C: 1115 Kbytes It is important to not overload the controller because the remaining memory can also be used for COV subscriptions (the last line in the table above). If there is no memory available, then opening a graphic which creates COV subscriptions could overrun memory or operate very slowly

Difference between "Workstation" and "Workstation Professional" licenses

Issue Information is needed regarding the content of the various license types Product Line EcoStruxure Building Operation Environment Building Operation Workstation Cause If a standard Workstation license and a Workstation Pro. license are purchased, and are loaded on to a License server, when is the professional license used? Resolution The difference between the standard Workstation license and the Workstation Pro. license is that the professional license allows the usage of the editors (Graphics Editor, Function Block Editor, Script Editor, Menta Editor, WorkPlace Tech Editor). The licenses can be seen as a bundle of license features that can be checked in and checked out separately from each other. When a workstation attempts to use any of these editors the license server is asked to check out the license feature for that editor and if successful, that feature is "taken" and cannot be used by any other Workstation until the first workstation leaves the editor. This means that if you have one professional license, only one Workstation can use the same editor at the same time, if you e.g. have 2 professional licenses you can have 2 Workstations using the same editor at the same time. However, any Workstation can use any editor as long as there is a free license feature for it on the license server.
