Operator Panel OP3
Edition 11/99
Timers and Counters
With the OP3, you can access the SIMATIC S7’s timers and counters.
Examples of this have been implemented on the OP3 standard screens.
The following description of access to timers and counters refers to the Timer
and Counter standard screens. You can choose these standard screens from
the screen directory on the OP3.
8.1 Counters
For every counter that has been configured and enabled on the PLC, you can
have the OP3 display the current counter status. Call the Screens ³ Counters
standard screen. The following display appears, by way of an example:
67 COUNTER 1
235
Counter selected
Counter actual value
Counter setpoint
Exit from the standard screen by pressing ESCAPE.
There is no point in entering counter setpoints, since the values are
overwritten by the current contents of the accumulator on the SIMATIC S7
when the counter is called.
