PROFINET CPC20PN
Device The CPC20PN controls itself. It has the following features:
– The PROFINET interface (DAP) via which the master communicates with the CPC20PN
– CPC20PN holds the status of the controller.
– CPC20 / 18plus-AM03 connection module: it is possible to configure 1 to 16 modules.
18plus-TM03 transfer module / 18plus-AM03 connection module: it is possible to configure 1 to 16 modules.
Slots Slot 0:
Modules are shown here which are required for the PROFINET communication.
They do not have to be configured further.
Slot 1:
Here are the I/O data of the CPC20 controller. A sub-module with firm I/O assignment has already been
»plugged« in this slot. This sub-module contains 2 input and output bytes which are described in more detail
in the chapter Module I/O Data CPC20 controller.
This slot is firmly installed and cannot be removed.
Slot 2 -3:
The slots 2-3 correspond to the terminals of the 18plus-AM03 and hold three sub-module slots which
can be occupied dynamically by the PLC configuration.
The module type is not directly checked, i.e. if 4 x- AM03 modules are »plugged-in« during the project
planning stage, but eventually 8 x 18plus modules are connected, this configuration will boot correctly.
However, in this case only the first 4 circuit protectors will be included in the cyclical data exchange,
the remaining 4 will not be contained in the process data image.
The reverse case is equally allowed (8 x 18plus- AM03 module planned, but only 4 x 18plus-AM03
connected. In this case the lacking circuit protectors will be signalled as »not available« in the cyclical
process data image).
SubSlots Each module has three sub-slots:
Slot 1: total current of all connected channels
Slot 2: status and control bytes of the circuit protectors
Slot 3: measuring values of the circuit protectors
A corresponding sub-module (from the GSDML file) can be »plugged« into each slot or the slot can remain
empty. If the slot remains empty, no cyclical process data will be exchanged for the slot.
The quantity of the cyclically to be exchanged process data can be determined via this mechanism (on the
level of the number of 18plus modules) depending on the application.
