Number of the connected hosts in Modbus Alarm

some time ago I asked the following question:

It was about Modbus utility - how to trigger Modbus Alarm when voltage on the I/O Analog Pin drops below some level. The functionality was working for me very nice. I was just reading some register and comparing it with the threshold value…

Currently I need to do similar thing. I want to check number of currently connected devices and trigger an alarm when the number is higher than X. Is it possible to read that information from some register?

Best Regards


There is no specific register at this time, however, using custom modbus registers and a script of your own that print the number of hosts to the custom reg file, you can achieve what you need.

Thank You.
Any idea how I can get clients number via custom script?
