CM35 Counter Module

(4) J31069-D0416-U001-A5-7618

You can choose between automatic operation and CPU control to control the

digital outputs.

DO mode

Automatic:

When a counter starts, the related output
is switched on.
When the comparison value is reached,

the related output is switched off.
While counting is running, a switched on output can be
reset by the user program.

CPU control:

The user program specifies the status of the outputs.

The status is not linked to the counting procedure
(e.g., for adjustment mode).

DO mode can be specified for specific channels.
