Addressing
The address of a module is determined by its module position in the configuration
(see section 3.4.5).
PCD2 CPUs: The module addresses begin at base address 0 (zero) on
Slot 0 (addresses 0 to 15) and go up in increments of 16 to
address 127 on Slot 7, regerdless of the number of I/Os (16, 8 or 4).
PCD2.C2000 Determined by the module position in the configuration; also goes up
and C1000:
in increments of 16
Extension cables connect the expansion housing at the right-hand end of a row with
the first expansion housing at the left of the next row. The address of the first module
in a second or third row equals the address of the last module in the previous row
+16.
Address 255 is reserved for the watchdog relay. Modules that use this address must
not be installed in module position 16. For more details, please refer to
the section on the "Hardware watchdog".
Each additional PCD2.C2000/C1000 expansion housing provides space for 8/4 more
I/O modules. The connection to the next row is made via the 26-core extenstion cable
or the connector (see section 3.4.3).
Forces arising with too small cable radii (smaller than the natural radius) may
damage the plug connection.
The extension cables must not be plugged in or removed with the controller
connected to the power supply.
