Description

Features　　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　　SCADA communications　　Pulp and paper　　Foreign device data concentrator　　Pipelines and offshore platforms　　Minin　　Food processing　　Complete setup and monitoring of module through Debug port and user configuration file　　Some of the general specifications include:　　Flex backplane interface via I/O access　　Operation via simple ladder logic　　Supports Enron version of Modbus protocol for floating point data transactions　　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　　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.　　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.　　Module memory usage that is completely user definable　　Application port can emulate Modbus master or slave device　　Support for the storage and transfer of up to 5000 registers to/from the FLEX processor’s data filesModbus Master/Slave Communication Module MVI94-MCM 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 How to Contact Us: Sales and Support All ProSoft Technology® products are backed with unlimited technical support.

Compatible devices include not only Modicon PLCs (which all support the Modbus protocol) but also a wide assortment of end devices. A 5000-word register space in the module exchanges data between the processor and the Modbus network.
