14. RX (n+3) to RX (n+4): Address information A to Address information B
●
If RX (n+2) bit 0 (completion of connection information change) is turned off (set to ‘0’)
Address of S-LINK V I/O units recognized by the SL-VGU1-C will be stored.
Bit corresponds to the address will be turned on
(will be set to ‘1’).
●
If RX (n+2) bit 0 (completion of connection information change) is turned on (set to ‘1’)
Address of S-LINK V I/O units connected to the S-LINK V system, those error 3, 4, or 5 is detected will be
stored.
Bit corresponds to the address will be turned on
(will be set to ‘1’).
● Address that corresponds to the data stored in RX (n
＋
2) bit 8 to B (completion of address information
change bit 0 to 3) will be stored.
Bit corresponds to the address will be turned on
(will be set to ‘1’).

15. RY (n) bit 7: Error cancel
To cancel the error status, this bit will be turned on (will bet set to ‘1’).
If this bit is turned on, the error status will be canceled.
At the completion of error status canceling, turn off this bit (set this bit to ‘0’).
Note: If the cause of the error is not eliminated, the error signal will be output again.
16. RY (n) bit E: Transmission frame check request
Use the transmission frame check request to check whether the output data is transferred to the S-LINK V
unit. To send two different outputs to the same address, use this request signal. This is because if the next
data is set before transferring the previously set output data to the unit, the previously set output data will
be ignored. However, after setting output data, if this request signal is turned on (set to ‘1’), RX (n) bit E
(completion of transmission frame check) signal will be turned on (will be set to ‘1’) after transferring the set
output data to the unit.
Using the program, check whether RX (n) bit E (completion of transmission frame check) is turned on (set to
‘1’), and then set the next data to prevent an output data transfer error.
To repeatedly use the transmission frame check signal, turn off (set to ‘0’) RY (n) bit E (transmission frame
check request), and then check whether RX (n) bit E (completion of transmission frame check) signal is
turned off (set to ‘0’). After that, turn on (set to ‘1’) the transmission frame check request again.
