Parameter assignment options

Counting, measuring and position input with SSI absolute encoder
For the counting and measuring function and the position input with an SSI absolute
encoder, you have two options for parameter assignment and control of the technology
module:
● Configuration of a technology object and control using the related instruction:
When using an incremental or pulse encoder, we recommend the simple configuration
with graphic support using thee High_Speed_Counter technology object. A detailed
description of this configuration can be found in section High_Speed_Counter technology
object (Page 92) and below.
When using an SSI absolute value encoder, we recommend the simple configuration with
graphic support using the SSI_Absolute_Encoder technology object. A detailed
description of this configuration can be found in section Technology object
SSI_Absolute_Encoder (Page 136) and below.
For configuration of a technology object, select the operating mode (Page 174)
"Operating with "Counting and measurement" technology object".
● Parameter setting via hardware configuration (Page 183) and control via the control and
feedback interface of the technology module:
Select the operating mode (Page 174) "Manual operation (without technology object)" for
this.
A description of the control and feedback interface for TM Count and TM PosInput is
available in the following sections:
Assignment of the control interface (Page 185)
Assignment of the feedback interface (Page 188)
Position input for Motion Control
Alternatively, you have the option of using the technology module for position input for
Motion Control.
Select the operating mode (Page 174) "Position input for "Motion Control" technology object"
and assign the parameters of the encoder using the module parameters (Page 175) in the
device configuration of the technology module. You perform the rest of the configuration of
this application using an axis technology object of S7-1500 Motion Control .
Feedback from the technology module is returned by means of the feedback interface.
