SIMATIC S7-400
Function modules
FM 450-1 counter module
6/116
Siemens ST 70 · 2011
■
Overview
• Two-channel intelligent counter module for simple counting
tasks
• For direct connection of incremental encoders
• Comparison function with 2 specifiable comparison values
• Integrated digital outputs for outputting the response when the
comparison values are reached
Note:
SIMODRIVE Sensor/Motion Connect 500 feature incremental
encoders and preassembled connecting cables for counting
and positioning functions.
