The error codes can be queried on the INTERBUS master. They assist in trouble-
shooting in program development or indicate error situations in normal operation.
13.5 Example of a PCP Service
The PCP services are part of the commands which you can send to the INTER-
BUS master from your application program.
The following example shows the structure of a Write service that is used to con-
figure a slave, see chapter 13.3.8. With this service you tell the AS-i master which
slave type (including parameters and data direction) the AS-i master can expect at
which slave address.
