10.2 Using the CNTR-01 Module
This section explains how to use the CNTR-01 Module.
10.2.1 Overview
„ Module Overview
The CNTR-01 Module is equipped with 4 pulse input (PI) channels.
Each channel can accept either 5-V differential or 12-V voltage pulses. Connect 5-V differ-
ential inputs to connector CN1 and 12-V voltage inputs to connector CN2.
The CNTR-01 Module provides a PI latch function, which latches the counter value when a
latch signal is received, and a coincidence detection function, which generates an output sig-
nal and outputs an interrupt signal to the CPU-01 Module when the count matches a preset
value.
The following three methods can be used to count pulse input (PI) signals.
• Reversible counter
• Interval counter
• Frequency measurement
• Count data is input at regular intervals for each CPU-01 Module scan (high-speed or low-speed).
During each scan, count data is simultaneously input for all four channels.
• The user can specify whether each channel is to be used or not to be used. The processing times for
the CNTR-01 Module and CPU-01 Module can be reduced accordingly.
• The user must select up to four channels from a total of eight channels: Four 5-V input channels on
the CN1 connector and four 12-V input channels on the CN2 connector.
