hi, yes, there are input modules that can work as counter. for example this one, 6ES7521-1BL00-0AB0, can count up to 1 kHz frequency. There are much more modules that can count, also the compact-PLCs, 1511C and 1512C have 32 high-speed digital inputs for signals up to max. 100 kHz Have a look the technical data and the manual of the modules and PLCs. Here you can find all together in a collection: SIMATIC S7-1500/ET 200MP Manual Collection hope this helps, regards, |

You can use to read in an encoder:
To calculate the time between two digital signals:
