Functional Specifications
The MVI46-MNETC will operate on a local or remote rack. This module was created to improve the performance when servers are not needed on a Modbus TCP/IP network. The module supports up to 30 Clients with up to 16 commands for each Client, making it easy to enable/disable the commands from the ladder logic. The Client command control word contains one bit for each command.
Client Specifications
A port configured as a virtual Modbus Client device on the MVI46-MNETC module actively issues Modbus commands to other nodes on the Modbus network. Additionally, the Client ports have an optimized polling characteristic that polls servers with communication problems less frequently. The SLC 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.
