QUESTION:
Can you program the SM338 module with STEP7 Mini?

ANSWER:
There are 2 modules named SM338 that you must differentiate.

• One module is listed in the SIMATIC range. You can use STEP7 Mini to program this module SM338 POS_INPUT with MLFB 6ES7338-4BC00-0AB0, because you do not need any option software.
• The other SM338 for ultrasound is not listed. Information on it is obtainable via the SIEMENS sales partner in your Region. You need the STEP7 Basis Package for this SM338 (MLFB: 6ES7338-7UH01-0AC0) ultrasonic position decoder, because you have to install additional software for STEP7.
