*1 S_ERR : Connection Error with Sensor Amplifier Unit
This flag turns ON when the registered number of connected Sensors does not match the
number of Sensors available for communications, or when communications with a Sensor
Amplifier Unit fails after a connection with the Sensor Amplifier Unit has been established.
*2 BUSY_MSG: Explicit Message Communications in Progress with Sensor Amplifier Unit:
This flag turns ON when explicit message communications are in progress with a Sensor
Amplifier Unit.
Do not send a new explicit message or use I/O to send a command to the Unit while this
flag is ON.
*3 BUSY_IO: Command Execution in Progress with Sensor Amplifier Unit Using I/O
This output turns ON when remote I/O communications are in progress with a Sensor
Amplifier Unit.
Do not send a new explicit message or use I/O to send a command to the Unit while this
flag is ON.
*4 NORM_RES: Normal Response
Read the response data when this output turns ON.
*5 ERR_RES: Error Response
The command was not executed normally if this output is ON.
Check the contents of the command in the error response and try executing the command
again.
*6 Warning Flags
The bits between 00 and 15 that correspond to the unit numbers of the Sensor Amplifier
Units that are currently in a warning state turn ON.
