Basic parameters
You can establish the connection between the High_Speed_Counter technology object and
the technology module under "Basic parameters".
Module (TM Count and TM PosInput)
You select the technology module in a subsequent dialog box. All technology modules
(central or distributed) that are configured for use with a "Counting and measurement"
technology object under the S7-1500 CPU or ET 200SP CPU are available for selection.
After selecting the technology module, you can open the device configuration associated
with the technology module by clicking the"Device configuration" button.
The technology module parameter settings required for the use of the technology object are
made in the "Extended parameters" of the technology object.
Module (Compact CPU)
You can select a high-speed counter for the Compact CPU in a subsequent dialog. You can
choose any of the high-speed counters which are enabled and configured for use with a
technology object from "Counting and measuring".
After selecting the high-speed counter, you can open the device configuration associated
with the Compact CPU by clicking the"Device configuration" button.
The parameter settings of the high-speed counter required for the use of the technology
object are made in the "Extended parameters" of the technology object.
Channel
For a technology module with several counting channels, you can also select the number of
the counting channel for which the High_Speed_Counter technology object is to be valid.
Note
A channel can be assigned to only
one
technology object. A channel that is already assigned
to a technology object can no longer be selected.
Synchronization of the parameter values
If, after assignment of the channel to the technology object, there is an inconsistency
between the parameter values under "Parameters" and in the technology object, a button
with a corresponding inquiry appears. When you click the button, the parameter values
under "Parameters" are overwritten by the parameter values of the technology object within
STEP 7 (TIA Portal). The current parameter values of the technology object are displayed
under "Parameters".
