Modbus error check with Jazz

Recommended Posts

There is no simple Modbus "Check Alive", but you can make one with old school handshaking.


Put a timer in your slave logic that sets a bit every so often.  Have your master logic reset it as part of the write.  Then have another timer in the slave look to see if that bit stays on for too long.
