15.1.4 Activating controller outputs
CustomLogic cannot directly activate controller outputs that are configured for controller functions. For example, CustomLogic
cannot activate the
[Breaker] > Control > Open
digital output.
However, CustomLogic can activate external commands, for example, the
[Breaker] > Open
command. The CustomLogic command
has the same effect as, for example, the
[Breaker] > Command > Open
digital input. The controller only follows the external
command if the controller is in SEMI mode.
15.1.5 CustomLogic and Modbus
Each controller has 20 Modbus signals that can be assigned to contacts and coils.
When a Modbus signal is assigned to a contact, the contact can be activated and deactivated using the correct Modbus address for
the signal number.
When a Modbus signal is assigned to a coil, the state of the coil can be read using the correct Modbus address for the signal
number. It is not possible to use a Modbus interface to write a value to a Modbus signal that has been assigned to a coil.
More information
See
CustomLogic
in the
PICUS manual
for examples of how to configure a Modbus signal to a CustomLogic element.
15.2 Restrictions
15.2.1 CustomLogic reset on save
If you make a change to the CustomLogic and then save the change to the controller, all the CustomLogic states and timers are
reset.
15.2.2 CustomLogic under switchboard control
CustomLogic remains enabled when the controller is under switchboard control.
However, the controller does not accept external commands under switchboard control. For example, if CustomLogic activates a
command to open a breaker, the controller ignores the command.
If the logic should not be processed while the controller is under switchboard control, a open normally closed contact should be
added to the logic lines where necessary. Set the normally closed contact to
Mode > Inputs > Under switchboard control
.
