Which server am I connected to?

Michael

I have seen a lot of functions that give information on the servers, but the one i am looking for is elusive.

ServerIsOnline wil give me the status of the servers - both the primary and standby.

However, I am only communicating to one of them at a time.

How would I find out which one I am talking to?

  • The way I have always thought about this is that one server was doing the bulk of the communications, and the standby was monitoring it. The Alarm server is redundant, with 2 running at the same time, where the Trend and Report have 1 running and one not.
    I've worked thorugh this pretty well with the servers. Still having trouble in the I/O.
    For example, I would like to read the number of errors from an I/O device.
    IODeviceInfo("Device",20,sCluster)
    Client side functions (3) work fine, but it seems that the number of errors is a server side function.
    MsgRPC should get this, but if it is set as unblocked, it does not return a result and if it is set as blocked, the code trips an error and doesn't complete.
    How would you display the number of errors for an IODevice on the graphics?
