5) System set button (SW1)
The system set button is pressed to read and memorize the connection condition of the
S-LINK V
units. Later, it is possible to check Error 3, Error 4 and Error 5 using the present condition as the
basis.
Notes: 1) If the system set button is pressed when Error 3 occurs, the error is canceled. However, if the
cause of the error is not rectified, the error address is, from now on, missed out from the checked
items. (The address is considered to be in unit unconnected condition.)
2) If the system set button is pressed when Error 4 occurs, the error is canceled and the connection
condition including the addresses where Error 4 has occurred is read again and stored.
6) Transmission indicator (Green)
It blinks when communicating (during signal transmission) with the
S-LINK V
I/O units. (Turns
OFF during no transmission)
Blinking interval differs depending on the transmission speed. (A mode: Fast, C mode: Slow)
7) Busy indicator (Orange)
It lights up during the system setting or transmission process confirmation.
●
It lights up when the power supply (+24V and personal computer side) is switched on till I/O re-
fresh is started.
●
It lights up during the system setting (after pressing the system set button or executing system
setting from the personal computer side), and turns OFF when the system setting is completed.
8) Error indicator (Red)
It lights up when an error occurs on the
S-LINK V
system main cable. In case the cause of the er-
ror is eliminated, it blinks, and if the error No. is cleared with program, or when the system setting
is done, it turns OFF.
Notes: 1) Error 0 to Error 6 cannot be distinguished with the error indicator. Check with a program on
the VME bus system by using “
5) HML0 + 48: Error No. / Error state
” in “
4. Assignment on
Computer
.”
2) In case of turning OFF the blinking state, conduct it on the program.
