PROGRAMMABLE LOGIC CONTROL
Physical outputs are the real outputs of the Device. SIA-C has a trip output and two digital
outputs (
Output 2, Output 3
). Besides, the relay has 3 configurable LEDS, which receive
the same treatment as the physical outputs. All the outputs (Leds andphysical outputs) are
the result of a PROGRAMMABLE LOGIC CONTROL which can be configured from HMI or
from SICom software.
For each output, there is a LOGICAL GATE. It can perform a logical operation up to 4
binary states to obtain other binary result. In V3 of the PLC the LOGICAL GATES that are
supported by SIAC are:

LED 1
LED 2
LED 3

NOTE
: As it is described above, the options NOR4_LATCH and NAND4_LATCH are not
available in the relay. Although, using SICOM software allows the user to configure these
options, the relay will not recognize them, and it will not work properly.
By default, outputs configuration is:
