I have a couple of devices connected via RS485 bus.
On each bus, we installed a TCP/Serial gateways and configured Ignition with the Modbus RTU over TCP driver.
The problem here is when a device is not responding on time, we get a Timeout as expected, but then a “Bad Quality” data is shown.
We are asking, if could exists a way to configure a retry count or stale time, and only after this time or retries the data became Bad Quality.
Because, the data on the RS485 bus fails 5-10% of the requests, could be a simple way to filter false comm errors.
