7 Process, parameter, and diagnostic data
7.1 Process data
The system sends and receives cyclic process data. The process data sent by the CAPA-
ROC system to the controller is referred to as input process data below. Cyclic data sent by
the controller to the CAPAROC system is referred to as output process data.
All values without “hex” are decimal values.
7.1.1 Input process data slot 0/subslot 2 (global system data)
The global input process data sent from slot 0/subslot 2 is 5 bytes.
This data is structured as follows:
* The permissible total current of the system depends on the temperature derating
** The value range that can be represented does not correspond to the permissible operating voltage range

Bit Description Value range
0 Word 0 ... 7 Total current (HIGH byte) 0 ... 500 (= 0 ... 50.0 A)*
1 0 ... 7 Total current (LOW byte)
2 Word 0 ... 7 Input voltage (HIGH byte) 1000 ... 3050 (= 10 ... 30.50 V)**
3 0 ... 7 Input voltage (LOW byte)
4 Byte 0 Undervoltage 0 = input voltage OK
1 = input voltage <9.5 V
1 Overvoltage 0 = input voltage OK
1 = input voltage <30 V
2 Channel error 0 = no errors
(group message) 1 = error at at least one channel
3 I > 80% warning 0 = no I > 80% warning in the system
(group message) 1 = at least 1 channel where I ≥ 80% I

4 Total current shutdown 0 = no total current shutdown
1 = at least one module shut down due to
total current overrange
