140EIA92100 Schneider Electric AS-i Master Module

140EIA92100 Schneider Electric AS-Interface Master Module

The Schneider Electric 140EIA92100 serves as a dedicated AS-Interface master for Modicon Quantum automation systems. This module communicates with up to 31 slave devices over a single two-wire cable. It supports both digital inputs and outputs, making it ideal for distributed I/O applications. Additionally, the 140EIA92100 reduces wiring complexity significantly compared to traditional point-to-point connections.

AS-Interface Communication Features

This master module complies with AS-i version V1 and supports profile M2. It operates at a transmission rate of 167 kbit/s, ensuring rapid data exchange with connected slaves. The maximum bus length reaches 100 meters without a repeater, which covers most standard factory floor layouts. For longer distances, you can add repeaters to extend the range further.

The 140EIA92100 handles up to 31 slave devices per master. Each slave can provide multiple I/O points, giving you a total of 124 discrete inputs and 124 discrete outputs. The module calculates the AS-i cycle time as 156 × (n + 1) µs for 31 slaves, or 156 × (n + 2) µs for other configurations. Specifically, the maximum cycle time is only 5 ms, which supports real-time control requirements.

Power Supply and Electrical Ratings

This module receives its power directly from the AS-Interface line at 30 V DC. The rated supply voltage ([Us]) is 30 V DC, and the module includes internal reverse polarity protection. This protection safeguards the module against accidental wiring errors during installation. Current consumption is typically 60 mA at 30 V DC, with a maximum of 100 mA.

The Schneider Electric 140EIA92100 connects to the AS-i network via a 3-pin male SUB-D connector. This standardized connector ensures reliable and secure attachment to the AS-i cable. The module also features IP20 protection, making it suitable for installation in control cabinets with proper enclosure ratings.

Addressing and Slave Management

Addressing follows the standard AS-i protocol, allowing you to assign unique addresses to each slave device. The module supports up to 31 server devices, each with its own address. Address assignment can be performed manually or using an external addressing tool. The 140EIA92100 simplifies commissioning with its comprehensive LED indicator array.

Local Signalling and Diagnostics

The front panel of the 140EIA92100 includes 32 LEDs that display slave addresses and the status of slave I/O bits. These LEDs provide immediate visual feedback for troubleshooting. You can quickly identify which slave is active, which I/O points are on, and whether any communication errors exist. This diagnostic capability reduces downtime and speeds up maintenance.

System Configuration and Capacity

You can install multiple AS-Interface masters within a single Quantum system. Specifically, the 140EIA92100 allows up to two modules per distributed drop, and up to four modules per local or remote drop. This flexibility lets you scale your AS-i network to accommodate hundreds of I/O points across large facilities.

Installation Guidelines for the 140EIA92100

First, power down the Quantum rack before installing the Schneider Electric 140EIA92100. Insert the module into an available slot and secure it with the retaining clips. Next, connect the AS-i cable to the 3-pin SUB-D connector on the front panel. Ensure proper polarity when terminating the AS-i cable to avoid communication issues.

Then, apply 30 V DC power to the AS-Interface line. The module will power up and begin scanning for connected slaves. Assign addresses to your slave devices using a handheld addressing unit or software tool. Finally, configure the module in your Quantum programming environment. The 140EIA92100 is compatible with all standard Quantum CPUs.

Frequently Asked Questions (FAQ)

1. How many slaves can the 140EIA92100 support?
The 140EIA92100 supports up to 31 AS-Interface slave devices. Each slave can provide multiple I/O points, giving you up to 124 digital inputs and 124 digital outputs.

2. What is the maximum cycle time for this master module?
The maximum cycle time is 5 milliseconds. This fast response makes the Schneider Electric 140EIA92100 suitable for time-critical automation tasks.

3. Can I use multiple 140EIA92100 modules in one Quantum system?
Yes, you can install up to four 140EIA92100 masters per local or remote drop, and up to two per distributed drop. This allows you to expand your AS-i network significantly.

4. Does the module require an external power supply?
The 140EIA92100 receives power directly from the AS-Interface line at 30 V DC. You do not need a separate power supply for the module itself, only for the AS-i network.

5. What does the 32-LED array on the front panel show?
The 32 LEDs display slave addresses and the status of each slave's I/O bits. This helps you monitor communication and diagnose faults quickly without using a programming terminal.
