I want to develop a JAVA code using MODBUS4J which should discover and read data from modbus controllers present in its network.
Is there a feature like autodiscovery in modbus like that of bacnet?
I have a doubt if my code should be a master or slave?
if master can a network have multiple masters? for network might have a plc or a master modbus controller.
if a slave can a slave communicate with a master to get all data?
