8 Cyclical I/O data
Depending on the planned module type and the selected
sub-modules, a varying number of data bytes are exchanged in
the cyclical data traffic.
The system allows individual determination per slot if I/O data
(status/control), measuring values and/or total current shall be
transmitted. The GSDML file made available for the projecting
tool allows the related configuration the system recognises all
permitted configurations and processes the cyclical data defined
in the projection.
Only the module I/O data CPC20 controller is firmly pre-set and
cannot be removed because the input bytes hold vital failure and
diagnostic information as described in the following.
byte type range description
status controller 0 HighByte
1 LowByte Word 0xFFFF Bit 0 = no configuration data available
Bit1 = invalid configuration data
bit 2 = reserve
bit 3 = reserve
Bit4 = command buffer overflow
bit 5 = reserve
bit 6 = reserve
Bit7 = no communication with at least one PWR board
Bit8 = reserve
Bit9 = CPC temporary error
Bit10 = CPC hardware error
Bit11 = reserve
Bit12 = reserve
Bit13 = reserve
Bit14 = reserve
Bit15 = reserve

8.2 Submodule Status/Control
Depending on the number of 18plus-AM03 connection modules
used (one 18plus-AM03 module corresponds to two channels),
per channel one byte input data with the status of the circuit
protector and one byte output data for control of the circuit
protector are exchanged here. Example:
8 18plus-AM03 connection modules equal 16 channels. This
results in 16 bytes for status information and 16 bytes for control
for the data exchange.
Addressing is effected according to the
18plus-AM03 sequence
18plus-AM03 1, channel 1.1 byte address [0]
18plus-AM03 1, channel 1.2 byte address [1]
18plus-AM03 2, channel 2.1 byte address [2]
…….
8.1 Module I/O data CPC20 controller
The 2 bytes input data contain the following global error and
diagnostic messages. This module does not contain any output
data.
