•
The terminal is in TEST mode (TEST-ACTIVE is high) and the function has been
blocked from the HMI (BlockIOC=Yes)
•
The input signal IOC--BLOCK is high.
The HSOC function is disabled if:
•
The terminal is in TEST mode (TEST-ACTIVE is high) and the function has been
blocked from the HMI (BlockHSOC=Yes)
•
The input signal HSOC--BLOCK is high.
The IOC--BLOCK and HSOC--BLOCK signals can be connected to a binary input of
the terminal in order to receive a block command from external devices or can be soft-
ware connected to other internal functions of the terminal itself in order to receive a
block command from internal functions.
Through an OR gate the blocking signals can be connected to both binary inputs and
internal function outputs.
