The MVI94 Modbus Master/Slave Network Interface Module allows Rockwell Automation FLEX I/O processors to interface with Mitsubishi Heavy Industries equipment.
The inRAx Modbus Master/Slave Communication Module is designed to allow FLEX processors to interface easily with Modbus protocol-compatible devices and hosts.
The MVI94-MCM module acts as an input/output module between the Modbus network and the Rockwell Automation backplane. The data transfer from the FLEX processor is asynchronous from the actions on the Modbus network.
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 Technology web site).
Applications using the Modbus Communication Module can be found in many industrial sectors and in the following applications
Some of the general specifications include:
Applications using the Modbus Communication Module can be found in many industrial sectors and in the following applications
The MVI94-MCM module accepts Modbus function code commands of 1, 2, 3, 4, 5, 6, 15 and 16 from an attached Modbus master unit. A port configured as a Modbus slave permits a remote master to interact with all data contained in the module. This data can be derived from other Modbus slave devices on the network, through a master port, or from the FLEX processor.
A port configured as a virtual Modbus master device on the MVI94-MCM module actively issues Modbus commands to other nodes on the Modbus network. One hundred (100) commands are supported on each port. Additionally, the master port has an optimized polling characteristic that polls slaves with communication problems less frequently. The FLEX processor can be programmed to control the activity on the port by actively selecting commands from the command list to execute or issuing commands directly from the ladder logic.
