Instruction SSI_Absolute_Encoder
SSI_Absolute_Encoder
The SSI_Absolute_Encoder instruction is part of the SSI_Absolute_Encoder technology
object. It supplies the control and feedback interface of the TM PosInput technology module.
The SSI_Absolute_Encoder instruction thereby forms the software interface between the
user program and the technology module. It must be called cyclically from the user program
in order to synchronize the input and output data.
The SSI_Absolute_Encoder instruction can be used for the TM PosInput of both the S7-1500
and ET 200SP systems alike. The TM PosInput modules can be used centrally and
decentrally. The instruction applies in each case to the channel of the technology module
that was assigned to the associated technology object.
