    I assume you are talking about TEC controllers.
    The controllers attached to a specific panel would be available via the FLN device list. Pull that either from Insight or the panel.

    You can write ppcl to monitor cabinet failures on the network. Can you write a sample here so we can check it out? It might be easier to help you figure it out.

    i have a statement in ppcl that starts with

    5720 IF(NODE6 .EQ. FAILED) THEN.........

    this is where i am trying to find the node. where would i find node 6 if it failed?

    If this is an rs485 (p2) bln than look in system profile and the panel where this program will be on the same bln where node 6 resides. It will be address 6. If its Ethernet than you should actually have a panel named node6.

    dumb question but i would presume that you cannot monitor your own node??

    Not using program. There are others ways to see it other than monitoring thru program

    Monitor "your own node"

    APOGEE Powers Process Control Language (PPCL) User’s Manual

    Syntax
    LINK
    Use
    This resident point indicates the condition of communications.
    Depending on the status of the communications link, a point contains
    the value 0or 1.
    •If the LINK value is 0, the node where the LINK point resides is
    not communicating with the network.
    •If the LINK value is 1,the node where the LINK point resides is
    actively communicating with the network.
    Example
    300 IF (LINK.EQ.0) THEN ON(ALARM)

    That is correct but if the node is failed it's not sending the alarm to the front end. You can view it locally via mmi or an alarm output.

    Correct Willy, I've never found that LINK point very useful. The only thing I did with it one time was to attach a light to a DO and turn it on when the panel would drop off the network. Then, people just walking thru could see if it was offline again (this was a problem panel due to crappy wiring - since repaired).
