Position decoder module SM 338
The position decoder module SM 338 supports the connection of up to 3 SSI encoders to S7-300 and ET 200M. The isochronous response and latch functions over digital inputs also support time-critical applications in the field of position sensing.
SM 338 provides encoder values for further processing in the STEP 7 program. Further processing is performed in the CPU, e.g. with Easy Motion Control. Parameterization is performed with STEP 7 without the need for additional configuration software.
