5.6.8.3 Available PCP services
In the following, you will find all the parameters and their contents which are
returned by Lenze controllers. All other transmission parameters of the stated
PCP services can be obtained from the corresponding INTERBUS master
description.
Parameters are transmitted via the PCP channel (PCP = Peripherials
Communication Protocol). This is carried out via PCP services.
The following PCP services are supported by Lenze controllers:
l Initiate: Build up connection between INTERBUS master and controller
( ¶ 5.6-49)
l Abort: Disconnect ( ¶ 5.6-49)
l Read: Read parameters ( ¶ 5.6-49)
l Write: Write parameters ( ¶ 5.6-49)
