Function:
Description of choice:
See description of [0] - [28] in
Analog/digital outputs
.
Control word bit 11/12
, relay 1 and relay 2 can
be activated via the serial communication. Bit 11
activates relay 1 and bit 12 activates relay 2.
If the parameter 556
Bus time interval function
becomes active, relay 1 and relay 2 will become cut off
if they are activated via the serial communication.
