9. RWrm (m+1) bit E: Completion of transmission frame check
At the completion of transmission frame check, this bit will be turned on (will be set to ‘1’).
If RWwm (m+1) bit E (transmission frame check request) is turned off (set to ‘0’), this signal will be turned off
(will be set to ‘0’).
10. RWrm (m+1) bit F: 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.’
11. RWrm (m+2) bit 0 to 8: Number of nodes bit 0 to 8
●
If RWrm (m+3) bit 0 (completion of connection information change) is turned off (set to ‘0’)
This signal indicates the number of nodes (
S-LINK V
I/O units) recognized by the
SL-VGU1-C
.
Numbers 0000 to 0100H (0 to 256) can be input.
●
If RWrm (m+3) bit 0 (completion of connection information change) is turned on (set to ‘1’)
This signal indicates the number of nodes (
S-LINK V
I/O units) connected to the
S-LINK V
system, those
error 3, 4, or 5 is detected.
Numbers 0000 to 0100H (0 to 256) can be input.
12. RWrm (m+3) bit 0: Completion of connection information change
If RWwm (m+3) bit 0 (connection information change request) is turned on (set to ‘1’), this bit will be turned
on (will be set to ‘1’), and if RWwm (m+3) bit 0 (connection information change request) is turned off (set to
‘0’), this bit will be turned off (will be set to ‘0’).
Check whether the data of RWwm (m+3) bit 0 (connection information change request) corresponds with the
data of RWrm (m+3) bit 0 (completion of connection information change), and then read out RWrm (m+2) bit
0 to 8 (number of nodes bit 0 to 8), and RWrm (m+4) to RWrm (m+F) (address information 0 to 191 / 192 to
255) to prevent an error in reading information.
13. RWrm (m+3) bit 8: Completion of address information change
If RWwm (m+3) bit 8 (address information change request) is turned on (set to ‘1’), this bit will be turned on
(will be set to ‘1’), and if RWwm (m+3) bit 8 (address information change request) is turned off (set to ‘0’),
this bit will be turned off (will be set to ‘0’).
Check whether the data of RWwm (m+3) bit 8 (address information change request) corresponds with the
data of RWrm (m+3) bit 8 (completion of address information change,) and then read out RWrm (m+C) to
RWrm (m+F) (address information 128 to 191 / 192 to 255) (refer to page 32).
14. RWrm (m+4) to RWrm (m+F): Address information 0 to 191 / 192 to 255
●
If RWrm (m+3) 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 RWrm (m+3) 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’).
●
If RWrm (m+3) bit 8 (completion of address information change) is turned off (set to ‘0’)
Information of address 128 to 191 of
S-LINK V
I/O units will be stored in RWrm (m+C) to RWrm (m+F)
(address information 128 to 191 / 192 to 255).
Bit corresponds to the address will be turned on (set to ‘1’).
●
If RWrm (m+3) bit 8 (completion of address information change) is turned on (set to ‘1’)
Information of address 192 to 255 of
S-LINK V
I/O units will be stored in RWrm (m+C) to RWrm (m+F)
(address information 128 to 191 / 192 to 255).
Bit corresponds to the address will be turned on (set to ‘1’).
