Pleiger Control Loop
Manual version 2018-03
•
Up to two digital outputs can be controlled by the SCADA system in the same way. If the equivalent
bit in the register is set, the output on the VCI card will be set until the bit in the register is reset
again. Depending on the parameters the outputs can be also set to 0 if the communication from the
VCI to the busmaster(s) fails for more than 5s!
NOTICE
Combinations and parameters for extended inputs and outputs
Not every combination of functions of inputs and outputs can be realized!
For example, one key switch and one button can’t be combined to be used as local
control unit but, as another example, it is possible to use both ouputs for local indica-
tion and both inputs to collect digital or analog sensor signals for the SCADA-system.

CAUTION
Malfunction / Damage
Take care that the DIP-
Switches 9 & 10 are only in “ON”-Position, if the equivalent in-
put is used with an analog 4-20mA signal! In case of external switches or digital sensor
signals, the switch has to be “OFF” (factory setting)!
