Information
•
Group activation by analogue output, relay and MODBUS can also be combined.
•
Ensure an ascending and complete sequence when assigning the groups. This means that if, for
example, the function for a fourth group was assigned for an output, there must already be an
assignment for groups 2 and 3 (
IO Setup).
•
The group control only becomes active once a group function is allocated to an output (analogue,
relay, MODBUS).
9.9.9.1 Variant “ 0 ” : One controlled group and up to three switched groups
The programming described below applies equally for group control by analogue outputs, relay
outputs and MODBUS.
For group control by the analogue outputs
“ A1 ” / “ A2 ” and the relay outputs “ K1 ” and “ K2 ” , the
available outputs must be observed in the selection of the version (combinations are possible).
Example: Required assignment for a controlled and a switched group
•
For activation by analogue output ( IO Setup) or MODBUS ( MODBUS Master)
– Function
|
A
|
for group 1 (0 - 100 % controlled)
– Function
|
5A
|
for group 2 (0 / 100 % switched)
•
For activation of Group 2 by relay ( IO Setup)
– Function
|
A
|
for group 1 (0 - 100 % controlled)
–
Function
|
8K
|
for group 2 (ON / OFF switched)
The function
|
11A
|
must be allocated additionally to Group 3 for one controlled and two switched
groups.
The function
|
12A
|
must be allocated additionally to Group 4 for one controlled and three switched
groups.
