Default:
Execute directly
Explanation:
•
Execute directly
The command is transferred immediately to the CPU.
•
Select and operate
(select and execute)
The command is transferred to the communication module after selectio
n
in the master station.
The communication module acknowledges receipt of the selection ASDU
with the Qualifier "S/E (Type 6) <1> select".
After receiving the acknowledgment the master sends the execute
command with the Qualifier "S/E (Type 6) <1> execute". Only then does
the communication module transfer the command to the CPU.
