Modbus RS485: Acknowledge Event
-
Hi,
I have a Modbus RTU Data source, and are getting the following error from most of the 5 Slaves on the BUS, but only from register 0:Urgent 'Modbus RS485': Cool Room Temperature — Modbus RS485: Acknowledge
The slaves only have two registers being polled, 0 and 1.
Update period: 30 seconds
Timeout: 1000ms
Contiguous batches onlyThe event lasts only 0 millseconds
Has anyone seen this before?

So it's a standard Modbus response:
05 ACKNOWLEDGE
The slave has accepted the request
and is processing it, but a long duration
of time will be required to do so. This
response is returned to prevent a
timeout error from occurring in the
master. The master can next issue a
Poll Program Complete message to
determine if processing is completed
