Hello,
I'm a novice PLC user but advanced Excel VBA user. I've created a program to capture and email data from our PLC. The capture happens once an hour as it reads the tags in the PLC. Our second shift ends at 3:30AM on Saturday mornings and RSLinx isn't detecting when they shut the machines off for the weekend. It also doesn't detect when the PLC is turned back on for the morning shift start on Monday.
I read that there may be an issue with RSLinx where it loses it's "mind" or stops "auto-Browsing" if it doesn't detect a PLC for a period of time.
Is there a way to keep this auto browse alive even when PLC's are powered off? Like is there a "timeout" setting that can be changed in RSLinx to maintain the autobrowse longer?
I have VBA to look for tags to see if the PLC is online, but I have to uncheck and then recheck the "Autobrowse" checkbox to get RSLinx to see the state change in the PLC after the weekend.
It seems to be an issue for both PLC shutdown and startup.
I appreciate all your thoughts and responses.
