The Schneider Electric 140ESI06210 adds serial communication capability to any Modicon Quantum CPU. This ASCII serial link module features two independent RS232C ports for device connectivity. It handles standard ASCII protocols for data exchange with external equipment. Additionally, the 140ESI06210 includes a built‑in calendar clock and ample memory for message storage.
This module provides two non‑isolated RS232C ports conforming to DIN 66020 standards. Each port uses a 9‑pin SUB‑D connector for easy cabling. The transmission rate reaches up to 19.2 kbit/s, which suits most industrial serial applications. Furthermore, the maximum cable distance between devices is 20 meters (65.6 feet). This range is adequate for panel‑mounted equipment or nearby workstations.
The Schneider Electric 140ESI06210 supports message nesting up to eight levels. This nesting capability allows complex communication sequences without losing data. The module can store up to 255 individual messages, with each message holding a maximum of 127 characters plus one checksum byte. Therefore, you can pre‑program extensive libraries of commands or responses for different devices.
Onboard memory includes 128 kB of flash storage and 32 kB of RAM. The flash memory retains your configuration and message tables even after power loss. Meanwhile, the RAM handles active message processing and buffering. The buffer size is 255 input bytes and 255 output bytes, ensuring smooth data flow between the module and the CPU.
The 140ESI06210 also includes a real‑time calendar clock. This clock enables time‑stamped data logging and scheduled communication tasks. For addressing, the module requires 12 input words and 12 output words. This addressing scheme integrates seamlessly with the Quantum backplane.
The Schneider Electric 140ESI06210 works with all Quantum CPUs, offering broad compatibility across system configurations. It is supported by several programming software platforms, including Concept V2, ProWORX 32 V2, ProWORX NxT V2, and Unity Pro V2. Consequently, you can use your preferred development environment to configure the module.
Typical applications include connecting barcode readers for tracking, weight scales for process monitoring, and printers for label generation. The module also interfaces with serial terminals for operator interaction. Its versatility makes the 140ESI06210 a valuable addition to many automation systems.
This serial module draws 300 mA from the bus and dissipates a maximum of 2 W. These modest power requirements keep your system's total load within limits. The standard Quantum format fits into any slot in the rack. Its weight is only 0.3 kg (0.7 lb), making it easy to handle during installation.
First, power down the Quantum rack before inserting the Schneider Electric 140ESI06210. Select an available slot and slide the module in until the retaining clips lock. Then, connect your serial devices to the two 9‑pin SUB‑D ports using shielded cables. Ensure proper pin‑to‑pin wiring according to your device specifications. For RS232C, keep cable lengths under 20 meters to maintain signal integrity.
Next, configure the module using your programming software. Set the baud rate (up to 19.2 kbps), data bits, parity, and stop bits to match your external devices. Create your message tables and download them to the module. Finally, test the communication by sending and receiving test strings. The onboard LEDs provide status feedback during commissioning.

1. What type of serial communication does the 140ESI06210 support?
The 140ESI06210 supports ASCII transmission over RS232C. It handles standard character‑based protocols for devices like barcode readers, printers, and weighing scales.
2. How many devices can I connect to this module?
The Schneider Electric 140ESI06210 has two independent RS232C ports. Each port connects to one serial device. For multiple devices per port, you would need external switching hardware.
3. What is the maximum message length I can send?
Each message can contain up to 127 characters plus one checksum byte. The module stores up to 255 different messages in its flash memory.
4. Can I use this module with older Quantum CPUs?
Yes, the 140ESI06210 is compatible with all Quantum CPUs. It works with Concept V2, ProWORX 32 V2, ProWORX NxT V2, and Unity Pro V2 software.
5. Does the module retain messages after a power cycle?
Yes, the 128 kB flash memory stores message tables permanently. The 140ESI06210 retains its configuration and messages even when power is removed.
