Interaction capabilities
NK8232 and NK8235 provides programmable interaction programs, including single or
multiple triggers (incoming events) and single or multiple effects (outgoing control
actions). Interactions are only possible between locally connected subsystems.
 For supported subsystems see Interactions [➙ 12]
 Logical combinations: AND, OR, XOR, NOT
 Delay of effects (wait): configurable 0…6500 sec
 Max. # of typical interactions (1-6 triggers, 1-4 effects): 500
 Total # of field points used in triggers/effects: 5000
 Max. # of field points/interactions that can be combined in a trigger expression: 255

 Up to 4 DF80xx modules in total
– 1 DF8090 Power supply supervision module
– Up to 4 DF8020 relay output modules
– Up to 4 DF8040 non supervised inputs modules
– Up to 4 DF8045 supervised NC input modules
