SIMATIC S7-300
Function modules
FM 350-1 counter module
■ Overview
• Single-channel intelligent counte r module for simple counting
tasks
• For direct connection of incremental encoders
• Comparison function with 2 selectable comparison values
• Integrated digital outputs to output the response upon
reaching the comparison value.
• Operating modes:
- Continuous counting
- One-shot counting
- Periodic counting
• Special functions;
- Set counter
- Latch counter
• Start/stop counter with gate function
4
Note:
SIMODRIVE Sensor/Motion Connect 500 feature incremental
encoders and preassembled connecting cables for counting
and positioning functions.
