DESCRIPTION:
MODBUS RS-485 Communication Module
The Micron Modbus RS-485 board offers all of the benefits of the Micron RS-485 board and is fully compliant with the Modbus over Serial Line Specification V1.0 (2002). This includes RJ45 connectors and half or full duplex operation (jumper selectable).
A benefit of Modbus is that up to 32 devices by different manufacturers can share the same RS-485 data line, be connected using similarly-wired RJ45 connectors, and be addressed using the same protocol.
A computer is required in a Modbus system. The Modbus Serial Line protocol is a master-slave protocol, where a master node (computer) issues commands to slave nodes (peripheral devices) on the bus and processes responses.
The Micron Modbus RS-485 board features two 8-pin RJ45 jacks wired in parallel, one of which is equipped with two indicator LEDs. The Modbus protocol is implemented by the microcomputer in the Micron main board and is compliant with the Modbus RTU or ASCII transmission modes. |
