Assignment Items
● If buffer memory assignment pattern 1 is used:
1. RX (n) bit 0 to RX (n+o-1) bit F, RWrm (m,) RY (n) bit 0 to RY (n+o-1) bit F, RWwm (m): S-LINK V I/O data
These are I/O data signals of the S-LINK V system.
Note: The value ‘o’ depends on the number of occupied CC-Link stations. [2 stations = 3, 3 stations = 5, 4 stations = 7]
2. RX (n+o) bit 9: Completion of initial data setting
This signal will be turned on if the RY (n+o) bit 9 (initial data setting request) is turned on.
If the RY (n+o) bit 9 (initial data setting request) is turned off, this signal will be also turned off.
Note: The value ‘o’ depends on the number of occupied CC-Link stations. [2 stations = 3, 3 stations = 5, 4 stations = 7]
3. RX (n+o) bit A: Error status
This signal will be turned on if one of errors 0 to 6 is detected on the S-LINK V system.
Note: The value ‘o’ depends on the number of occupied CC-Link stations. [2 stations = 3, 3 stations = 5, 4 stations = 7]
4. RX (n+o) bit B: Remote READY status
This signal will be turned on if the SL-VGU1-C enters the READY status (exits from the BUSY status).
If the RY (n+o) bit 9 (initial data setting request) is turned off, this signal will be also turned off.
Note: The value ‘o’ depends on the number of occupied CC-Link stations. [2 stations = 3, 3 stations = 5, 4 stations = 7]
5. RY (n+o) bit 9: Initial data setting request
The SL-VGU1-C will not use this signal to set or modify the initial data.
Note: The value ‘o’ depends on the number of occupied CC-Link stations. [2 stations = 3, 3 stations = 5, 4 stations = 7]
6. RWrm (m+1) bit 0 to 6: 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 between +24V 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.
7. RWrm (m+1) bit 7: 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’).
