RMC100 Modbus Plus
Fieldbus Communications for RMC100 Motion Controllers
Modbus Plus is Schneider Electric's proprietary network designed for industrial control applications. A variety of third-party vendors build Modbus Plus devices. The network enables programmable controllers to communicate with remote devices such as the RMC100 controller.
With its high data rate of 1Mbaud, Modbus Plus is excellent for transferring position, parameter, command, and graphing data between the programmable controller and the RMC100.
Features
- Allows up to 32 devices to be connected directly to a network cable up to 1500 feet in length. (Repeater devices are available to extend the network in both distance and device count.)
- Modbus Plus masters can access all of the RMC's 64k, 16-bit holding registers
- Up to 100 registers can be read from or written to the RMC in a single operation
- Supports Modbus Plus Global Data
