Setting UP the CPU for the Pulse Catch Inputs
The DL240, DL250–1 or DL260 CPUs checks the V-memory to see if there is a
D2–CTRINT Module present. There will be the value 10, 20, 30, 40, 50 or 60 in
V7633 if the module has been properly configured. If the CPU finds that a Counter
Interface module is present, other V-memory locations will be checked to see how
the module has been configured.
The values can be entered into memory by using either a handheld programmer or
by editing them into a control program using DirectSOFT32. The following
examples will show how to use DirectSOFT32 to configure the Pulse Catch Inputs.
If Mode 50, Pulse Catch Input, has been chosen as the primary function, the value 50
must be placed in V7633. The following DirectSOFT32 diagram shows the setup
procedures for communicating with the DL240/250–1/260 CPU. Refer to the
DirectSOFT32 Programmers User Manual for more details.

Editing the D2–CTRINT setup at the beginning of the user program is the most
efficient method for setting up the counter mode. Should there be a need to change
any of the counter setup values after the PLC has been put in the RUN Mode, use the
Memory Editor to change the values. These values will only be temporary. They
should be put into the program if they are to be used permanently.
