ProSoft Technology, Inc. Communication Interface Module MVI56-DH485

The MVI56-DH485 module actively issues DH-485 commands to other nodes on the DH-485 network. One hundred user-defined commands are supported by the module on each port. The ControlLogix processor can be programmed to control the activity on the port by actively enabling or disabling each command directly from the ladder logic. The module also accepts DH-485 commands from an attached DH-485 master unit (for example, SLC 5/03 processor ladder logic MSG instruction). The module permits a remote master to interact with all data contained in the module. This data can be derived from other DH-485 slave devices on the network through a master port or from the ControlLogix processor.
