SYSTEM ROLE

Where the TM PosInput 1 Fits

The module belongs to the SIMATIC ET 200SP technology-module range and is intended for counting and position acquisition from encoder signals. It can be used with RS-422 incremental encoders or SSI absolute encoders, making it suitable for machine axes and processes where position, movement or counting values need to be captured by the control system.

↗

Position Acquisition

Useful when a machine process depends on accurate encoder-based position values.

◌

Counting Tasks

Suitable for high-speed counting applications where encoder pulses must be captured by the automation system.

◇

Encoder Replacement

A practical search target when an existing ET 200SP position module develops encoder, counting or diagnostic faults.

In a running machine, loss of position acquisition can affect motion sequences, counting operations and process synchronization. Selecting the correct replacement module helps reduce unnecessary control-system downtime.

BUYER SEARCH QUESTIONS

6ES7138-6BA01-0BA0 FAQ

Practical questions buyers commonly consider before replacing or integrating the module.

Can I use 6ES7138-6BA01-0BA0 with an RS-422 incremental encoder?

Yes. The module is designed for counting and position acquisition with RS-422 incremental encoders. It supports A/B phase-shifted encoder signals and A/B/N configurations.

What should I check if my application uses an SSI absolute encoder?

Check the encoder interface, telegram length and transmission rate. The TM PosInput 1 supports SSI absolute encoders through RS-422, with configurable telegram lengths from 10 to 40 bits and clock rates up to 2 MHz.

Is 6ES7138-6BA01-0BA0 suitable when high-speed pulse acquisition is required?

It supports incremental encoder input frequencies up to 1 MHz. With quadruple evaluation, the counting frequency can reach up to 4 MHz.

How many digital I/O points are available on this TM PosInput module?

The module provides 2 digital inputs and 2 digital outputs. These I/O points support technology functions associated with counting and position acquisition.

Which BaseUnit should I prepare for 6ES7138-6BA01-0BA0?

The Siemens product specification identifies this TM PosInput 1 as suitable for BU type A0. Confirm the installed BaseUnit configuration before replacing an existing module.
