I have two processors where I am using the XSIG symbols to communicate between the two. The problem of course with the older XSIG symbol is that they don't force the signals to stay in sync if one processor reboots or drops off line. From reading the help doc on the XSIG symbol, it looks like you can update or clear the values of the XSIG using \xFD or \xFC respectively. I have been tinker with updating the signals, but with no luck.
Would anyone have an example program on how to do this properly and efficiently?
Also, I understand I could issue the update command on system start of either of the processors, but what about if one of the processors simply goes off line. Is there a socket signal I can monitor to track the online status of a processor? I've looked but I must be looking in the wrong place.
Lastly, is there any reason to use the clear command to clear all the signals when trying to keep these in sync? Wouldn't I just want to issue update commands.
Thanks a bunch
