1.1 Features
1.1 Features
Two methods of wiring may be employed, depending on the application: standard wiring
or loop wiring.
Example: Standard wiring
In this method, wiring is done from the control section using
an S−LINK exclusive flat cable and an end hook−up connector
is connected at the end of the main cable. The maximum cable
length is 200 meters (400 meters if a booster is used).

Example: Loop wiring
The S−LINK exclusive flat cable from is run from the controller,
and the end is connected back to the controller. The loop can
have a maximum length of 200 meters. The end connector is
connected at approximately the mid−point of the loop (the
position furthest from the S−LINK unit). Even if the main
signal/power line is broken at one point, the system does not
go down and signal transmission continues.

2.1 Parts Related to S−LINK Operation
Notes
•If ERR1 (Error 1) occurs by itself, the protective function which
guards against a short−circuit between D and G has been
activated. To cancel the protective function, turn off the power
supply to the S−LINK, and then repair the cause of the
short−circuit. (The short−circuit protective function is
maintained as long as the power supply to the S−LINK is on.)
•If the power supply to the S−LINK is turned off, ERR1 (Error 1)
and ERR3 (Error 3) light.
•ERR4 (Error 4) is maintained. To cancel this error, either turn
the power supply to the FP2 off and then on again, or press the
system SET button to reset it if the RUN/CHK. selector switch
is set to the RUN position, or turn the power supply to the
S−LINK off and then on again.
3I/O indicators (ON/OFF indicators)
The CPU with S−LINK is equipped with Channel 1 and Channel 2 I/O indicators.
The on/off status of the various S−LINK system addresses are displayed in units of
eight points. The address to be displayed is selected using the 6MONITOR
switch. For detailed information, refer to section “5.4.5.3 Confirming the On/Off
Status of Addresses”.
4RUN/CHK. selector switch
Set to RUN: This is the normal operation mode.
Set to CHK.: This is the Check mode (for detailed information, see 8System SET
button).
The following items can be confirmed using the system SET button.
When normal: The number of units that the FP2 S−LINK unit recognizes as
connected to it are displayed as a blinking display by the 5
ADDRESS display, and all of the addresses light in sequential
order.
If an error occurs: All of the addresses where errors have occurred are displayed
in sequential blinking displays (when ERR4 occurs) by the 5
ADDRESS display.
Note
After confirming the above items, always return the system to the
operation mode (RUN) side.
For a CPU with S−LINK, switching between RUN and CHK is
carried out on both channels (the Channel 1 and Channel 2
sides).

2.1 Parts Related to S−LINK Operation
5ADDRESS display (2−digit hexadecimal display)
This displays the transmission status, the number of units connected, and the
addresses of the various units.
During normal transmission:
The “ ” shaped charactor rotates in the clockwise direction.
If an error occurs:
In case faults occur at several locations, the smallest error address is displayed
and the decimal points light up simultaneously. Therefore, if only one S−LINK I/O
device is connected beyond the cable disconnection point, the decimal points do
not light up.
Decimal points
Note
With a CPU with S−LINK, the above is displayed for the channel
selected using the (10) ADDRESS display selector switch.
6MONITOR switch
The CPU with S−LINK is equipped with Channel 1 and Channel 2.
The display addresses for the 3I/O indicators (corresponding to the S−LINK I/O
device addresses) are specified in units of 8 points.
For detailed information, refer to section “5.4.5.3 Confirming the On/Off Status of
Addresses”.
7I/O setting switch (MODE )
The CPU with S−LINK is equipped with Channel 1 and Channel 2.
These are used to specify the number of input/output points for the S−LINK
system (32, 64, 96, or 128 points). Set value is read only once, when the power
supply to the FP2 is turned on.
For detailed information, refer to section “3.2 Specifying the Number of
Input/Output Points”.

2.1 Parts Related to S−LINK Operation
8System SET button
The CPU with S−LINK is equipped with Channel 1 and Channel 2.
When the RUN/CHK. selector switch is set to RUN:
Pressing the system SET button reads the connection status for the S−LINK
system and stores it in the memory. At this point, the 5ADDRESS display lights
for a given period of time. (if the same address has been specified for more than
one unit, it is counted as one unit. A maximum of two units can have the same
address.) In subsequent operation, the S−LINK unit checks for errors using the
connection status registered at this time.
(The output unit data effective at the time that the system SET button was pressed
is retained.)
When the RUN/CHK. selector switch is set to CHK.:
When normal: Each time the system SET button is pressed, the number which the
S−LINK unit recognizes as connected to it is displayed as a blinking display by the
5ADDRESS display, and all of the addresses light in sequential order, starting
with the smallest (the display is repeated).
If an error occurs: Each time the system SET button is pressed, all of the
addresses where errors have occurred are displayed by the 5ADDRESS display
in a sequential blinking display, starting with the smallest (when ERR4 occurs).
Note
If the RUN/CHK. selector switch is set to the RUN position and the
system SET button is pressed while an error is in effect, only the
number of units that can be confirmed at that point are stored in
the memory. There is a possibility that units where the error has
not been corrected will not be recognized (if this happens, they
will not be a target for the check).
9S−LINK terminal block
The CPU with S−LINK is equipped with Channel 1 and Channel 2 S−LINK terminal
blocks.
The power supply and signal wires of the S−LINK are connected to the terminal
block.
The S−LINK terminal block is a connector type, and can be detached from the
S−LINK unit for wiring operations.
For detailed information, refer to section “4.1 Wiring Methods for S−LINK Main
Unit”.
10 ADDRESS display selector switch
This is used to switch the contents displayed by the ADDRESS display between
the Channel 1 and Channel 2 sides.
1: Contents are displayed on the Channel 1 side (the S−LINK 1 side).
2: Contents are displayed on the Channel 2 side (the S−LINK 2 side).
