Hello!
When setting up LM5Cp-DR with 3 serial ports we cannot get data from the 3rd port via Modbus.
When connecting to port 3, data from Slave are transmitted at first, but after a few minutes the exchange stops, error messages are received.
When switching the same line from several Slaves to another port, the exchange is stable.
This problem is detected on several LM devices.
LM firmware was updated to 20200129, but it didn't help.
Your port testing script launched between Port2 and Port3 say "OK".
