The I/O Mapper is used for point-to-point communications where it is required to send input information from a PM16DI or PM8AI input module to a PM16DO or PM8AO output module over the network. The I/O Mapper is the Modbus master and all I/O modules must be set up as slaves. The I/O Mapper is only required if there is more than one pair of modules on the network.
