11.7.31 Digital outputs (4.3.9)
Fig. 72 Digital outputs
Description
In this display, the digital relay outputs of the Control MPC can be
set. Each output can be activated and related to a certain
function.
As standard, the Control MPC has two digital outputs.
If the Control MPC incorporates an IO 351B module (option), the
number of digital outputs is 9.
In the display, all digital outputs are shown so that their physical
position in the Control MPC can be identified.
Example
DO1 (IO 351-41) [71]:
DO1 Digital output No 1
(IO 351-41) IO 351B, GENIbus number 41
[71] Terminal No 71
For further information on the connection of various digital
outputs, see the wiring diagram supplied with the CU 351.
Setting range
In the display Digital outputs (4.3.9), the digital output to be used
is selected.
