LINK System Address Recognition
4.6.1
Recognizing the Address
Before the S

LINK system is being operated for the first time, turn on the power supply
and then press the system SET button.
When the system SET button is pressed, the number of connected devices recognized
by S

LINK control unit blinks on the error address display in hexadecimal.
ERROR ADDRESS display
(Displaying in hexadecimal)
System SET button
If the actual number of connected devices differs from the number displayed, since an
unrecognized S

LINK device exists, check for address overlapping, improper
connection, etc..
Subsequently, an error check is carried out based on this status. When an address is
recognized, that status is stored in the EEPROM, so it is not necessary to press the
system SET button after that point (each time the power supply is turned on).
When the power supply is switched on for the first time after completing the S

system wiring, an arbitrary error display may appear. This does not indicate any
abnormal operation. If the system SET button is pressed, this display is erased.
If an error address is displayed during operation, confirm the address, and then turn off
the power supply, correct the address at the location where the error occurred, and turn
the power supply on again. Check to make sure the error address display has
disappeared. (Do not press the system SET button in this case.)
If the system SET button is pressed after an error has occurred and before it is canceled,
the error will be canceled. If the cause of the error has not been corrected at that point,
however, be aware that the I/O device for that address will be skipped during any
subsequent checks.
Note
If the system SET button is pressed without recovery having
been made, that status will be recognized for that address, and
any locations where recovery has not been made will not be
recognized.
