Overview
The 57C442B is an Intelligent Interface Module for the AutoMax PLC / DCS 5000 systems. It contains an on-board processor and memory, enabling it to manage complex asynchronous serial communication protocols independently of the main AutoMax CPU. The “B” revision indicates updated hardware and firmware, improving compatibility and performance. This module is critical for connecting AutoMax systems to third-party equipment, MES, or SCADA systems, allowing seamless protocol conversion and robust data exchange.
Technical Data
| Parameter | Specification |

| Model Number | 57C442B |
| Product Type | Intelligent Interface Module |
Typical Applications
The 57C442B is essential when the AutoMax system must integrate with external devices or supervisory systems:
-
SCADA integration – Communicating process data to higher-level plant systems
-
Third-party equipment – Connecting to bar code readers, industrial printers, or specialized instruments
-
Asynchronous network management – Handling data formatting and protocol conversion to free the main CPU for control logic
By offloading communication tasks, the module ensures the main CPU can focus on high-speed automation tasks while maintaining reliable plant-wide data exchange.
Frequently Asked Questions (FAQ)
Q1: What does “Intelligent” mean in this context?
A: The module has its own processor and memory, allowing it to perform protocol translation, error checking, and message handling independently of the AutoMax CPU.
Q2: Are the communication ports configurable?
A: Yes, ports can be configured via jumpers or software to support RS-232, RS-422, or RS-485, making the module versatile for different network topologies.
Q3: Does the 57C442B require separate programming?
A: Configuration of baud rate, parity, stop bits, and protocol is performed via dedicated setup software. The AutoMax CPU defines the data to be sent or received.
Q4: How is this module different from a standard digital I/O card?
A: Standard digital I/O handles simple ON/OFF signals. The 57C442B manages structured, packetized data over serial networks, acting as a gateway between AutoMax and external systems.
