Product Introduction
The Schneider Electric 140ESI06210 is an ASCII Serial Link Communication Module designed specifically for use within the Modicon Quantum automation platform. This module provides a robust and flexible serial communication interface that allows the Quantum PLC to connect and communicate with third-party devices that use ASCII-based serial protocols. Its primary role is to establish point-to-point data exchange through RS-232 and RS-485 standards, enabling integration with barcode scanners, printers, controllers, and various serial instruments.
The 140ESI06210 supports both ASCII Master and Slave modes, making it versatile for various communication topologies. With its independent channel configuration, event-driven operation, and customizable data parsing logic, it has become a favored solution for system integrators and OEMs looking to integrate legacy serial devices into modern control architectures.

Frequently Asked Questions (FAQ)
-
Q: What types of devices can I connect to the 140ESI06210 module?
A: Any device that communicates via ASCII over RS-232 or RS-485, such as barcode readers, label printers, or serial meters. -
Q: Can the module be configured to use RS-232 and RS-485 simultaneously?
A: No, it supports one serial communication type at a time per channel. -
Q: Does the module support Modbus protocol?
A: No, this module specifically supports ASCII character-based communication, not Modbus RTU or TCP. -
Q: Is the module suitable for high-speed data exchange?
A: It supports baud rates up to 115200 bps, which is sufficient for most ASCII communication needs. -
Q: How is data handled in the PLC application?
A: ASCII strings received are stored in user-defined memory areas and can be parsed using string manipulation functions. -
Q: Can I use multiple 140ESI06210 modules in one Quantum rack?
A: Yes, multiple modules can be installed as long as the backplane has available slots and power. -
Q: What software is used to configure this module?
A: Unity Pro or EcoStruxure Control Expert software is typically used for configuration and diagnostics. -
Q: Does the module support transparent mode communication?
A: Yes, it allows unstructured data pass-through for flexible protocol handling. -
Q: How are transmission errors handled?
A: Errors can be detected using diagnostic bits and handled within the PLC logic or via retries. -
Q: Is the module firmware-upgradable?
A: Firmware is generally fixed, but always check with Schneider’s support portal for possible updates.
