    产品简介:
    Modbus Master/Slave Communication Module MVI69-MCM MVI69-MCM Interactive Tour The MVI69 Modbus Communication Module allows Rockwell Automation CompactLogix processors to interface easily with other Modbus protocol compatible devices. Compatible devices include not only Modicon PLCs (which all support the Modbus protocol) but also a wide assortment of end devices. The module acts as an input/output module between the Modbus network and the Rockwell Automation backplane. The data transfer from the processor is asynchronous from the actions on the Modbus network. A 5000-word register space in the module exchanges data between the processor and the Modbus network.

    Features and Benefits
    The inRAx Modbus Master/Slave Communications module (MVI69-MCM) is designed to allow CompactLogix processors to interface easily with Modbus protocol-compatible devices and hosts.

    Many host SCADA packages support the Modbus protocol, while devices commonly supporting the protocol include several PLCs, as well as many other third party devices in the marketplace. (For a partial list of devices that speak Modbus, please visit the ProSoft Tested section of the ProSoft web site).

    Applications
    •Applications using the Modbus Communication Module can be found in many industrial sectors and in the following applications
    •Foreign device data concentrator
    •Pipelines and offshore platforms
    •Food processing
    •Mining
    •Pulp and paper
    •SCADA communications
    •Supports Enron version of Modbus protocol for floating point data transactions.

    Modbus Slave Protocol Specifications

    The ports on the MVI69-MCM module can be individually configured to support the slave mode of the Modbus protocol. When in slave mode, the module can accept Modbus commands from amasterto read/write data stored in the module's internal registers. This data is easily transferred to the CompactLogix processor's data registers.
