SIMATIC S7-300
Function modules
FM 350-2 counter module
■ Overview
• For direct connection of 24 V incremental encoders, directional
elements, initiators or NAMUR sensors
• Compare function with programmable comparison values
(number depends on operating mode).
• Integrated digital outputs to output the response upon
reaching the comparison value.
• Operating modes:
- Continuous/one-shot/periodic counting
- Frequency/speed control
- Period measurement
-Proportioning
4
Note:
SIMODRIVE Sensor/Motion Connect 500 feature incremental
encoders and preassembled connecting cables for counting
and positioning functions.
