To return the I/NET system to the File equalization mode you need to do the following steps. Shut down the I/O Server Driver if it is running on the File Master. Go into the DbCreate Editor and perform a Database "Restore" to place the saved database back in the File Master. Promote the File Master PC to the File Master Mode. Wait until the snapshot is complete. Promote the Workstation PCs to the Client Mode one at a time. Wait until the snapshot is complete. Then verify the database was received at the workstation

Issue Needing to monitor a controller's online or offline status. I/NET AMT will generate a station lost alarm when a controller is offline, however it is sometimes desired to have a point that can be monitored to alarm as well. Product Line TAC INET Environment subLAN Controller Lan; C-LAN Xenta 527 Cause I/NET AMT will generate a Station lost alarm when a controller is offline, however it is sometime desired to have a point that can be monitored to alarm as well. Resolution Monitoring SubLAN Controllers Connect to the Sub Lan Interface Controller (7798, 7793) Create an internal DA point called LLSSPP_Offline, with LLSSPP being the address of the subLAN device Add a Calculation to the point LLSSPP_Offline Enter this Calculation: OLD(P0) Set P0 to equal any External input point the subLAN device LLSSPP Click okay The result of this calculation is that the point will equal 1 whenever the referenced point goes old Monitoring Controller LAN or C-LAN devices Connect the Controller you wish to monitor Change an external point's Global Level to "Link" (If a point already is set to system, use it.) Connect to a second Controller on the same physical C-LAN (for best results use one physically closer to the NPR or Tap) Create an indirect point referencing the point created in step 2 Create an internal DA point called LLSS_Offline, with LLSS being the address of the controller Add a Calculation to the LLSS_Offline point Enter this Calculation: OLD(P0) Set P0 to equal the indirect point created in step 4 Click OK The result of this calculation is that the point will equal 1 whenever the indirect point goes old, which should only occur when the controller is offline.  Monitoring NPR or Xenta 527 devices Connect to a Controller under the device you wish to monitor Change an external point's Global Level to "system" (Use an existing global point if available) Connect to a second Controller under the device you wish to monitor Change an external point's Global Level to "system" (Use an existing global point if available) Connect to a controller underneath a different NPR or 527  Create an internal DA point called Link _LL_Offline, with LL being the Link address of the 527 or NPR being monitored Create 2 indirect points referencing the global points created in steps 2 and 4 Add a Calculation to the Link _LL_Offline point Enter this Calculation: OLD(P0)&OLD(P1) Set P0 and P1 to equal the indirect points created in step 7 Click okay The result of this calculation is that the DA point will equal 1 whenever both of the referenced indirect points go old.  This should only happen when communication is interrupted to both controllers indicating the most likely cause is the NPR being offline. Please be aware of other potential causes of 2 controllers on the same link going offline. Examples include power circuit failure or cut wire when selecting which controllers to monitor. 

Issue When using PIN code or PIN with card number for door entry, the door does not open. A time out message "Entry PIN t/o" is shown in AMT. Product Line TAC INET Environment I/NET PIN Pad Reader Cause There may be two causes of this message: There is an output format for PIN Pad called burst format. There are several types of burst format available, for example 4 bit, 8 bit, 26 bit etc. For I/NET, it only accepts 8 bit and 26 bit type. If the burst format isn’t correct, there will be "Entry PIN t/o" message appeared, which means timeout for waiting for PIN entering. The digits of PIN are less than 6 bits. Resolution The following solutions are recommended for the two causes of this issue: For cause 1, the burst format of the PIN pad should be changed to 8 bit or 26 bit (Usually using 8 bit. If the extended PIN function is needed, 8 bit type should be chosen). For HID reader, there is a configuration card to change the burst format to specific type. Refer to HID relative documentation. NOTE: In most instances the Configuration Cards must be presented to the reader within 5 seconds of powering up the reader. For cause 2, if the digits of PIN are less than 6 bits, a "#" button needs to be pressed after entering the PIN. If this solution can't work, you can change the PIN to 6 digits by adding "0" ahead of the PIN. For example, the PIN is "3325", the PIN entered should be "003325".

Issue Coefficient table is full when adding a MR-VAV to an SLI controller. Product Line TAC INET Environment I/NET Site with MR-VAV Cause Coefficient table is full when adding a MR-VAV  Resolution An MR-VAV needs 7 Conversion Coefficients in order to complete the update MCI, but it can re-use coefficients which already exist in the table,e.g.0.018 and -148 for thermistors. If your table is full, see if you have duplicates of values in your Coefficient table. If you do re-direct, the points that have the same values. For example if 4 and 15 are the same values then select coefficient 4 for all of the points using coefficient 15 and change 15 to 0 and 0. That will open up one coefficient at line 15. See if their are more to open up. If not and you have close values, you might merge the values that are close together. Check to see how much it changes your actual output value. If it isn't much then that will probably work fine. I change some of my CFM Coefficient tables to make an 8 in. duct to match a 10 in. duct and the actual CFM did not change enough to worry about. If the value is close but not close enough, try adjusting the hardware coefficients for those points to fine tune them. If you then get an error indicating that your engineering table is full, open that one up to do the same as above. Point CFM, percentages, etc. to one CFM and one percentage.

Resolution ADI Z-NET is a proprietary network system/protocol that can interconnect up to eight graphic panels so that they appear as one larger (higher point count) MODBUS interface port. Refer to TCON 231: Smoke Control Systems Manual, ADI Z-NET for more information.

Issue Why is it recommended that the Firefighters Smoke Control Station Interface (FSCSI) database consists entirely of internal points and point extensions? Environment Firefighters Smoke Control Station Interface (FSCSI) Cause This allows the same database to be used regardless of whether the FSCSI is an ICI PCU or even an MRI. Resolution This allows the same database to be used regardless of whether the FSCSI is an ICI PCU or even an MRI. For more information see TCON 231, Smoke Control Systems Manual, Database Logic.

Issue Monitor the communication integrity of sub-LAN smoke control points Environment sub-LAN controllers Smoke Control Cause Smoke control systems must maintain communication with the sub-LAN controllers at all time. Interruptions in communication must be immediately known and responded to. Resolution Create a single point that will go OLD if communication is lost to any of the smoke control sub-LAN controllers. Refer to TCON 231, Smoke Control Systems, Manual, sub-LAN monitoring for more information.

Issue Limit access options of the users of the I/NET system. How many passwords are allowed? Environment I/NET User administration Cause There are many reasons to limit the access of different users in I/NET. One, for example, is if the HVAC is part on the Smoke Control Strategy.  Resolution The host password scheme covers over 100 individual host/system functions and capabilities. The number of uniquely defined users, when unique passwords for each, is virtually unlimited at the hosts. Refer to TCON 231, Smoke Control Systems Manual, System Access Control, Passwords for more information.

Issue Elevators do not allow free access when unlocking the elevator reader with a time schedule Environment I/NET Elevator control Cause The clue is "elevator READER".
