High-speed Counters Section 5-1
■ Creating the Ladder Program
Programming in Cyclic Task
Use CTBL(882) to start the comparison operation with high-speed counter 0
and interrupt task 10.
Programming in Interrupt Task 10
Create the processing performed by interrupt task 10.
5-1-8 Additional Capabilities and Restrictions
Restrictions on High-
speed Counter Inputs
• The Phase-Z signal + Software reset method cannot be used when the
high speed counters are operating in Differential Phase or Pulse + Direc-
tion Input Modes and the origin search function is enabled for the pulse
output (in the PLC Setup). The Phase-Z signal + Software reset method
can be used when the high speed counters are operating in Incrementing
or Up/Down Input Modes.
• When a high-speed counter is being used (enabled in the PLC Setup), the
input cannot be used as a general-purpose (normal) input, interrupt input,
or quick-response input.
