Using the High_Speed_Counter technology object

3.1

Convention

Technology module: We use the term "technology module" in this documentation both for the
technology modules TM Count and TM PosInput and the technology component of the
compact CPUs.

High_Speed_Counter technology object

STEP 7 (TIA Portal) supports you in the configuration, commissioning and diagnostics of
counting and measuring functions for the following technology modules with the "Technology
objects" function:
● You configure the High_Speed_Counter technology object in STEP 7 (TIA Portal) with the
settings for the counting and measuring functions.
● The corresponding High_Speed_Counter instruction is programmed in the user program.
This instruction supplies the control and feedback interface of the technology module.
The High_Speed_Counter technology object corresponds to the instance DB of the
High_Speed_Counter instruction. The configuration of the counting and measuring functions
is saved in the technology object. The technology object is located in the folder "PLC >
Technology objects".
The High_Speed_Counter technology object can be used for technology modules of both the
S7-1500 and ET 200SP systems.
Operating mode
In order to assign the technology module parameters using the technology object, you
specify the operating mode (Page 174) "Operating with "Counting and measurement"
technology object" in the hardware configuration of the technology module. This selection is
already preset.
