1. S-LINK V I/O data
These are I/O data signals of the
S-LINK V
system.
2. Errors 0 to 6
Error 0:
The system (controller) has a problem.
Note: Error 0 will stop the transmission.
Error 1:
If error 1 (short-circuit b24V and D) is detected on the main line of the
S-LINK V
system, this bit
will be turned on (will be set to ‘1’).
Note: Error 1 will stop the transmission. If the cause of the error is eliminated, the system will be automatically reset 5 seconds later.
Error 2:
If error 2 (short-circuit between D and G) is detected on the main line of the
S-LINK V
system, this bit will
be turned on (will be set to ‘1’).
Note: Error 2 will stop the transmission. If the cause of the error is eliminated, the system will be automatically reset 5 seconds later.
Error 3:
If an I/O unit has a problem or disconnected, this bit will be turned on (will be set to ‘1’).
Note: Error 3 will not stop the transmission.
Error 4:
If an unrecognized unit is added, this bit will be turned on (will be set to ‘1’).
Note: Error 4 will not stop the transmission.
Error 5:
If an output terminal of an output unit is shorted, or if I/O device driving power is stopped, this bit will be
turned on (will be set to ‘1’).
Note: Error 5 will not stop the transmission.
Error 6:
If system setting operation is not performed properly, this bit will be turned on (will be set to ‘1’).
Note: If system setting operation is performed properly, transmission will be started.
3. Error status
If an error is detected, this bit will be turned on (will be set to ‘1’). If the cause of the error is eliminated, this bit
will be turned off (will be set to ‘0’).
4. Number of I/O control points 0 to 3
The number of I/O control points will be stored.

5. Completion of transmission frame check
At the completion of transmission frame check, this bit will be turned on (will be set to ‘1’).
If transmission frame check request is turned off (set to ‘0’), this signal will be turned off (will be set to ‘0’).
6. BUSY
At power-on or during system setting operation, the system is not ready for transmission. In this case, this bit
will be turned on (will be set to ‘1’).
Note: In the
S-LINK V
User’s Manual, this signal is referred to as the ‘READY output.’
