When a protocol setting data error is detected, stores the protocol
number where the error was detected.
0 is stored if an error is detected in the packet setting or element
setting.
1 is stored if an error is detected in the protocol detailed setting.
When an error is detected in the protocol setting data, stores the
packet number that detected the error.
When an error is detected in the protocol setting data, stores the
element number where the error was detected.
Stores the protocol number of the registered protocol setting data.
Whether protocol setting data is registered or not is stored.
Stores the status of the protocol being executed at connection
No.1.
0: Unexecuted
1: Waiting for transmission
2: Sending
3: Waiting for data reception
4: Receiving
5: Execution completed
