Issue How to upgrade an Automation Server if Port 80 is closed and the Automation Server is placed behind a NAT router. Getting error message when upgrading: Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Building Operation Automation Server Premium Cause The problem is that the certificate are generated with the IP address off the Automation Server, and not the NAT Router IP. Resolution The Device Administrator has the option to add SAN's (Subject Alternative Name) and not just the address of the server. So add both the LAN and the WAN addresses in the SAN field when you generate the certificate and transfer to the server.

Issue According to the documentation the max cable lengths for the sensors connected to a Multical device are : Temperature sensors : 10m Flow Sensor : 2,5m Is it possible under any circumstances to extend the cable length up to 15m?   Environment Multical Cause The sensors come in pairs and are calibrated. They must never be extended. The longest length available is 10 metres. Resolution It is not possible to extend the cables to the sensors, as the devices are calibrated with the sensors delivered from the factory.

Issue What are the different override types on a 7780 Lighting Controller? Environment 7780 Lighting Controller Cause Different override types behave differently. Resolution Permanent means the override will continue indefinitely until: the button is pressed, the switch is moved, or the next time schedule off time happens. Timed means the override will run for a specified number of minutes (0-120).

Issue When trying to dump the Gerry Log from several controllers on the network, the header and errors appear to be identical. Environment CX99xx NetController Gerry Log Controller error log Cause Controller diagnostics. Resolution The Gerry log cannot be retrieved from a NetController without being physically connected to it via the RS232 connector.

Issue The MZ20A actuator stops controlling, and the Analogue Output remains at zero volts. Environment MZ20A MZ20A-R Actuators Surface Mount Cause If the controller power and battery switches are switched off, then when the power is switched back on, the Analogue Output remains at zero volts. Resolution To prevent is issue from occurring, it will be necessary to install a 2K2 ohm resistor between each channel and the common zero volt rail, as shown in the picture below.   Add the 2K2 Ohm resistors to the channels controlling the MZ20A actuators. These resistors do not need to be a close tolerance; a Carbon Film ¼ watt 5% is acceptable, (RS Stock No.135-881 or similar). Note – The MZ20A, are the only actuators that we are aware of that require this modification, therefore if the actuator is changed to another type, the resistor should be removed again.

Issue User keeps getting re-prompted for login for each station even though using virtual domain. Each station file has been edited to include the cookieDomain slot.  Also, each station’s “hosts” file has mapped every station’s IP address in the virtual domain to their hostnames. Everything seems to be configured correctly. Environment Niagara R2 Cause Host (station) names contained underscores. The hostname cannot contain underscores. Resolution The station must be renamed without underscores. Change the hostname to match the new station name.

Issue Created new bCX and can't see any of the system objects like system variables Environment CyberStation bCX4040 ACX57xx Cause CyberStation failed to fully create the new controller object in the database.   Resolution Delete the newly created controller from the ContinuumExplorer. Restart CyberStation. Create the controller again.

Issue Editing Multi-Stage control objects. Environment Sigma Control Multi-Stage Multi Stage Cause Multi-Stage control objects cause the controller to lock up when edited. Resolution The exact cause of this issue has not been located, but here are two suggestions. Download the complete object file periodically when editing these objects. If contingency logging is enabled on the multi-stage control object, it should be disabled before working on that object.

Issue In LonMaker, how do I get rid of multiple message tags within a base unit virtual function block? Environment Vista Site Cause In LonMaker, how do I get rid of multiple message tags within a base unit virtual function block? Resolution Right click on the VFB and select to delete NVs & MTs. All unconnected message tags will then be deleted.

Issue Only one of the readers on a 7920 DPU works Environment 7920 DPU Cause If you have defined one door in the DPU 7920, and the door’s Exit Reader parameter is set to anything other than "NO," then the second reader port automatically becomes the exit reader. Resolution If you have defined two doors in a DPU 7920, neither door can have an Exit Reader defined.

Issue After creating an output point on an XPD02 attached to a BCX the output is not working.  The CPU light of the XPD02 stays solid ON. Environment XPD02 BCX Expansion Modules Cause The expansion module was connected to the BCX while powered. Resolution Reload the BCX.

Issue When using PSI 4.1 in direct connect mode, the baud rate is modified and saved but it will not communicate at the new rate. Environment PSI 4.1 Cause A baud rate change in PSI direct connect mode does not take affect until the PSI program is closed and restarted.

Issue After a PIN Duress Event at a door, the Duress Trouble Input stays "ON" and is unable to reset or restore the trouble input until a Valid Access Event occurs at the door. Product Line EcoStruxure Security Expert Environment Security Expert Controller Cause Attempting to restore Duress Trouble Input remotely after an accidental PIN Duress Entry by Card Users Resolution This is the intended design and function of the PIN Duress Trouble Input. It is considered an extremely-high priority issue and must be restored by a specific physical action. Remotely restoring (via Keypad in another location) would defeat the purpose of the PIN Duress Trouble Input. This is intentional to prevent a real duress event from going unnoticed.
