Example of Controlling Two Counters via the Process Data

Prerequisite:
For the module in DTM, you have set the operating mode
"DIO module + 2 counters." For control of the counter via the output data, the
parameter "Simulation" must also be deactivated for the counter.
For the following example, heed the descriptions of the control byte
(section "Control Byte").
To control the counter via the process data (output data), the control mode
(set bit 7) must be activated. In this mode, the counter is stopped. Only with a set
control mode can you set the other bits individually or simultaneously. To check
the configuration, the control mode bit of the status byte is then read via the
process data (input data). When setting the start or limit value, the value must
remain in the output process image after resetting the control mode (at least one
cycle).
The control mode bit must be reset and then set again before configuring the
second counter.
