NOTE!
The user can change the value of the parameter P277, P278, P279 or P280 according to the Table 5.4
on page 5-8 . If the user does not respect the output availability for each operation mode an error will
be generated and the control unit (UC) will signalize through the status led and via the message “E0024”
on the HMI.

NOTE!
Changing the operation mode (P202) also changes the function of the Unit Control (UC) digital inputs
and outputs. The factory setting for the Control Unit (UC) digital outputs that are not predefined (internal
use) is Ladder. For more information, refer to the
Section 5.4 OPERATION MODES on page 5-10 of
this manual.
NOTE!
Only one Expansion Digital Unit (EDU) can be used with each Control Unit (UC). The factory setting
for the Expansion Digital Unit (EDU) digital outputs (P281 to P284) is Ladder and is not modified by
changing the operation mode, P202, different from what happens with the Control Unit (UC) outputs.
NOTE!
If a communication loss between the Control Unit (UC) and the Expansion Digital Unit (EDU) occurs, all the
Expansion Digital Unit (EDU) outputs are opened. After the communication is reestablished and a Control
Unit (UC) reset command is performed, the Expansion Digital Unit (EDU) outputs operate again according
to their configuration. If the communication is reestablished and the errors are not reset, the digital outputs
of the Expansion Digital Unit (EDU) will remain open; however, it is possible to check the state of the digital
inputs using parameter P086.
The parameters P012 and P013 present the status of the Control Unit (UC) digital inputs and outputs, respectively.
P012 – Digital Input I11 to I16 Status
Adjustable
Range:
0 to 63 Factory
Setting:
-
Proprieties:
RO
Description:
It monitors the status of the Control Unit (UC) digital inputs.
E.g.: P012 = 12 = 1100b. It means that the digital inputs I13 and I14 are actuated.
