4) I/O setting switch (SW3, SW4)
I/O setting is done for each 32 points with the I/O setting switch (SW3, SW4). Setting is read in
only once when power is supplied to the computer or when the reset command is executed on
the
S-LINK V
system side.
Changing the switch setting during operation is ineffective.

Note: When setting I/O through a program, set all the switches to input (ON).
5) System set button (SW1)
The system set button (SW1) 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 condi-
tion 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 recti ed, 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 con rmation.
It lights up when the power supply (+24V and computer side) is switched on till I/O refresh is
started.
It lights up during the system setting (after pressing the system set button or executing system
setting from the 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 software, 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
computer by using “
5) HML0 + 48: Error No. / Error state
” in “
4. Assignment on computer
.”
2) In order to change blinking condition to light turned OFF condition, carry out with “
Error No. clear
request
” explained in “
6) HML0 + 49: Command execution request register
” in “
4. Assignment
on computer
.”
9) Interruption setting (JP1)
It sets the resource generating the interruption.
Set by choosing one from IRQ 03, 04, 05, 07, 09 and “ineffective” with JP1.
