The MVI71-MNET is manufactured by Prosoft Technologies and is compatible with Allen-Bradley’s PLC family. This module is a Modbus TCP I/P interface module that supports Block transfer read (BTR) and block Transfer write (BTW) for implementing explicit Modbus messages. The module comes with an Ethernet application port that supports 10/100 Mbps and a configuration port that is compatible with the RS232 electrical standard used for module configuration. MVI71-MNET with Modicon Controller, PLC5/E rev C/N, D/E, E/D, SLC5/05 Series A, OS503 frn4, 1785-ENET Series A, rev D, Interchange V6.2, MicroLogix 1100/1400/ANY via 1761-NET-ENI, compact logix 1768-L43/L45 via 1768-ENBT, compact logix 1769-L32E/L35E/ Compatible This module includes a powerful Modbus network analyzer and supports special Modbus features such as command control, event commands, status, and more. It supports up to five (5) separate server connections on port 502 and the same functionality on port 2000. The module’s user data store stores error codes, network error counters, and port status, which can be mapped and analyzed to determine the health and performance of the network. The MVI71-MNET can be installed on a remote or local rack. It is a single slot module that fits into any available slot in the 1771 case. It has a minimum response latency of 0-65535 ms; Response timeout of 1-65535 milliseconds and configurable retry times of 0-20 milliseconds. It allows command control from ladder logic and allows pass configuration. The module has a third port capable of simulating the PLC’s channel 0.
