Description

07KP93 GJR5253200R1161: Product Overview
This component is a Modbus communication module (communication coupler) designed for ABB’s AC31 series programmable logic controllers (PLCs). Its position in an automation system is as a bridge between the PLC and external devices, such as human-machine interfaces (HMIs), variable frequency drives (VFDs), sensors, or supervisory systems. It resides in the PLC rack or a dedicated communication enclosure, interfacing with the AC31 CPU via the backplane to offload serial communication tasks.
The core functionality involves protocol conversion and data routing. It processes Modbus RTU (serial) and Modbus TCP (Ethernet, if supported via adapter) protocols, translating data between the PLC’s internal memory map and external device registers. The module handles read/write requests, error checking (CRC for RTU), and signal conditioning for serial lines, ensuring reliable data exchange in electrically noisy industrial environments. It also provides status monitoring via LED indicators for quick fault diagnosis.
This module belongs to the AC31 series PLC platform, recognized for its modularity, compact design, and broad compatibility with industrial communication standards. Benefits of the platform include simplified system integration through plug-and-play modules, reduced engineering time via standardized configuration tools (e.g., ABB Control Builder), and scalability from small machines to mid-sized process control applications. The AC31 series is widely adopted in discrete manufacturing and hybrid process industries for its balance of performance and cost-effectiveness.

Core Features & Customer Value​
Dual serial ports expand connectivity options. The two independent RS-232/RS-485 ports allow simultaneous connection to multiple devices (e.g., a VFD and an HMI), eliminating the need for external multiplexers. For engineers, this simplifies wiring schematics and reduces cabinet space; for end-users, it enables centralized control of distributed assets without additional hardware.
Modbus protocol compatibility ensures broad device integration. Support for RTU (serial) and TCP (with adapter) aligns with legacy and modern industrial devices, from older sensors to newer smart drives. This avoids costly protocol converters, streamlining system upgrades and protecting prior investments in field instrumentation.
LED diagnostic indicators accelerate troubleshooting. Visual status signals (power, communication activity, fault) allow maintenance teams to identify issues (e.g., cable disconnection, device timeout) without specialized tools. For plant operators, this minimizes downtime by enabling rapid on-site diagnosis before escalating to remote support.
Wide operating temperature range suits harsh environments. The -40°C to +85°C tolerance ensures reliable operation in unheated warehouses, outdoor enclosures, or high-temperature manufacturing areas (e.g., foundries). For facilities in extreme climates, this reduces the need for climate-controlled cabinets, lowering installation costs.
24V DC power supply simplifies integration. The module draws power from the PLC rack’s backplane or a standard industrial power supply, avoiding custom voltage conversions. Engineers can standardize on 24V DC distribution, reducing spare parts inventory and wiring complexity.

Typical Applications​
In an automotive assembly plant, the module connects an AC31 PLC to multiple VFDs controlling conveyor belts. Via Modbus RTU, it synchronizes belt speeds and reports fault codes to the HMI, ensuring smooth part transfer between workstations.
For a water treatment facility, it interfaces the PLC with pH sensors and chemical dosing pumps. The module relays sensor data to the PLC for closed-loop control, adjusting pump outputs via Modbus commands to maintain water quality standards.
In a solar power inverter station, it links the PLC to grid-tie inverters for remote monitoring. Modbus TCP (with adapter) enables real-time data logging of energy output, facilitating integration with the plant’s SCADA system for performance analysis.
At a food processing plant, the module connects the PLC to metal detectors and reject mechanisms. It triggers reject solenoids via Modbus when contaminants are detected, with status feedback ensuring compliance with food safety regulations.
