Pulse Counter Operating Mode
Switching reaction
of the digital
outputs
5-8
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.
