Issue Global and indirect points are very useful and are usually a mandatory part of most application programs. It is seen that in the event of a LAN failure or any failure of the indirect point being updated, the indirect point will be flagged as "Old Data." When this occurs any process using the indirect point as a variable, say, calculation extension, event extension will freeze at the last status/value before the old data on the indirect point was detected. Even though other parameters are still valid, the calculation and the event extensions will remain frozen, and some occasion remain in this state even when the old data is cleared from the source. Any subsequent process that uses the calculation or event definition will also be frozen. Any PID DDC Modules, Floating DDC Modules and 2 Position DDC Modules that uses the indirect point that has been flagged as "old data" will force those DDC modules to "Fail Safe" mode. Product Line TAC INET Environment ALL I/NET Software and controller LAN (CLAN) based controllers Cause LAN failure or any failure of the indirect point being updated. Resolution There are various tools available within I/NET to filter "old data" from subsequent control processes.  These include: Filtering by Calculation AVG operator function (including point types AI, DI and DO) Filtering by Direct Digital Control (DDC) Modules using either the Relay or HiLo modules Click Here to download a document which details these methods. For further details and recommendations when using Global and Indirect points, refer to the following I/NET Global and Indirect Points Overview and Recommendations.

Issue Doors/Elevator does not work when SCU/DPU is disconnected Product Line TAC INET Environment I/NET with Access Control Site Cause In normal operating situations, communication is always there, always working. Check that the network provided and the wires which tie the 7798C to the SCU are good and not an issue. If this is not the case, redo so that this communication is stable and constant. The SubLAN should always be connected. This RS-485 network should be stable. If not, investigate. This may also be a side effect of using large numbers. When disconnecting the 7798C from the SCU, the elevator does not work because the large numbers are stored in the 7798C and not in the SCU. If the individual is set to resident in the SCU then those are the only ones allowed to use the elevator. The others look to the SLI for permission to use the elevator. Resolution The SCU must remain in contact with the 7798C when controlling elevators. The communication between the SCU and the SLI, such as a 7798C, is required since an elevator is involved. The time schedules and floor mapping are in this SLI that is requested upon each time the elevator is used.  For more information on the I/NET network and environment, check Explain and define I/NET Ethernet, C-LAN, and Sub-LAN communication.
