Key Technical Specifications

Values below reflect typical MVI69‑family Modbus TCP CompactLogix modules; always confirm against the OEM datasheet for MVI69‑MBTCP before design or purchase.

• Platform: 1769 CompactLogix in‑rack, single‑slot module
• Supported controllers: CompactLogix with 1769 I/O bus; MicroLogix 1500 typically not supported
• Protocol: Modbus TCP/IP, Client and Server roles
• Ethernet interface: 1 × 10/100 Base‑T, RJ45, diagnostics and application traffic
• I/O image size: Up to roughly 240 input words / 240 output words (16‑bit integers)
• Internal data capacity: User data mapped between PLC and module, including integer and floating point
• Client connections: On the order of 10 Modbus TCP Client sessions (typical for “Lite” variants)
• Server connections: Two Modbus TCP Server sessions (commonly one on port 502 and one on an alternate port)
• Configuration tool: ProSoft Configuration Builder (PCB), configuration stored in the CompactLogix project file
• Power consumption: Approx. 450 mA @ 5 V (standard 1769 single‑slot load range)
• Operating temperature: 0 °C to 60 °C (32 °F to 140 °F)
• Storage temperature: −40 °C to 85 °C (−40 °F to 185 °F)
• Relative humidity: 5% to 95% non‑condensing

 

Product Introduction

ProSoft MVI69‑MBTCP is a CompactLogix in‑rack Modbus TCP/IP communication module that adds Client and Server capabilities to 1769‑based controllers. It targets small to mid‑size systems where a single CompactLogix CPU must interface with Modbus TCP drives, meters, PLCs, and remote I/O over Ethernet without an external gateway.

The module behaves as a co‑processor: it handles TCP connections and Modbus transactions while exchanging a fixed I/O image with the CompactLogix task via ladder logic. This approach limits impact on scan time and gives you deterministic mapping between Modbus registers and Logix tags, which simplifies troubleshooting and later expansions.
