Limitations and recommended setting
The maximum amount of slaves for the Modbus driver is 32 however keep in mind that
If a slave disconnects and the desired function is that the Modbus RTU master should connect to
it automatic once available the “Auto-restart Communication” option should be enabled.
The response timeout should also be considered, by nature Modbus RTU will perform a
sequential polling of all the slaves configured in the project. If communication fails for a slave the
polling will be delayed according to the Response timeout setting which will delay the normal
system response time accordingly.
Error checking
To check the communication status of a specific slave use the name of the slave as in the project
tree and the option .xError. In addition the .byModbusError will show more in detail the cause
of error.
