4.1.2

Reaction to CPU STOP

You set the reaction of the technology module to a STOP of the CPU on a channel-by-channel
basis in the basic parameters of the device configuration.

Parameter setting

You specify the properties of the technology module using various parameters. Depending on
the settings, not all parameters are available. When parameters are assigned in the user
program, the parameters are transferred to the module with the "WRREC" instruction and
data record 128 (Page 87).
You set the parameters of the module as follows in this operating mode:
1. Insert the module from the hardware catalog under "Technology modules".
2. Set the mode "Operating with technology object "Counting and measurement"" and the
further device configuration in the hardware configuration.
3. Insert the High_Speed_Counter technology object from the project tree in folder
"Technology objects > Add new object > Counting and measurement".
You can find information on configuring with a technology object in function manual
Counting, measurement and position detection
(http://support.automation.siemens.com/WW/view/en/59709820).
4. Open the configuration of the High_Speed_Counter technology object, e.g. using the
Configuration button
5. Set the parameters of the technology object.
6. Download the project to the CPU.
Note
The "Operating with "Counting and measurement" technology object" and "Manual operation
(without technology object)" operating modes apply to one channel in each case. As a result,
you can also use a module with both operating modes.

Reaction of technology module to CPU STOP
Meaning
The technology module remains fully functional. Incoming count pulses are pro-
cessed. The digital outputs continue to switch according to the parameter assign-
ment.
The technology module outputs the configured substitute values at the digital
outputs until the next CPU STOP-RUN transition.
The technology module is returned to its startup state after a STOP-RUN transition:
The counter value is set to the start value and the digital outputs switch according
to the parameter assignment.
The technology module outputs the values at the digital outputs that were valid
when the transition to STOP took place until the next CPU STOP-RUN transition.
If a digital output with the "At comparison value for a pulse duration" function is set
at CPU STOP, the digital output is reset after the pulse duration elapses.
The technology module is returned to its startup state after a STOP-RUN transition:
The counter value is set to the start value and the digital outputs switch according
to the parameter assignment.
