Index 5: Overview of PCP Modules and Status
3 bytes are provided for each connected PCP module.
Index 5 can be used to request the PCP communication status and even establish
communication if all PCP devices do not yet have a connection. To do this, write
01
hex
on slot 0, index 5.
Byte 1 Position in station (slot)
Byte 2 Status of PCP connection
0x00
hex
No connection
0x01
hex
Connection OK
0xFF
hex
Error establishing connection
Byte 3 Reserved
Index 6: Activation/Deactivation of Modules and Slots
Slots can be deactivated via index 6. This setting is stored retentively. During
power up, index 6 is adjusted to the configuration and parameterization stored on
the PLC. The deactivated modules are logically ORed. However, this means that
some slots will be configured although no modules are connected to them.
Make sure that no modules are inserted in "deactivated" slots. Otherwise a
configuration error will be displayed.

Bit = 1: Module and slot inactive
Bit = 0: Module and slot active
Index 7: Read back active/inactive terminals and slots
Index 7 can be used to read back which slots have been deactivated. The status is
obtained from the parameterization during hardware configuration and index 6 via
a logic OR operation.
