2. Cautions
This product is not equipped with a short-circuit protection circuit. Use a power supply having a
short-circuit protection function (e.g. fuse, etc.).
Verify that the supply voltage variation is within the rating. Also, check the voltage variation at the end terminal of
the transmission route, since voltage drop occurs depending on the diameter or the length of the transmission cable.
If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.)
terminal of the power supply is connected to an actual ground.
Do not use during the initial transient time after the power supply is switched ON. Furthermore, transmission
is not possible when the system is in Busy state (during switching ON of the power supply or system setting.)
Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (sin-
gle winding transformer) is used, this product or the power supply may get damaged.
In case a surge is generated in the power supply used, connect a surge absorber to the supply
and absorb the surge.
In case computer power supply is turned OFF rst, note that the output hold function of the
S-LINK V output units may not work.
Power supply
Do not run the wires together with high-voltage lines or power lines or put them in the same
raceway. This can cause malfunction due to induction.
Make sure to carry out the installation and wiring in the power supply OFF condition.
In order to reduce noise, make the wiring as short as possible.
Always use the speci ed transmission cable.
Take care that wrong wiring will damage the product.

3) Transmission mode setting switch, I/O control number setting switch (SW2)
This switch sets each system setting. The transmission mode setting switch (SW2-1, SW2-2) per-
forms A mode, B mode and C mode setting. Furthermore, the I/O control number is set with the
I/O control number setting switch (SW2-5 to SW2-8).
Setting is read in only once when power is supplied to the computer. Changing the mode switch
setting during operation is ineffective. (The setting cannot be changed with the reset command on
the
S-LINK V system side.)

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.

In case [Bank change-over response register = 00H] (Initial value) (S-LINK V I/O data)
This is an area to read out input data and write in output data of S-LINK V I/O units.
In case of input, “0: Input OFF” or “1: Input ON” can be read out for each bit.
In case of output, write in “0: Output OFF” or “1: Output ON” in each bit.
Notes: 1) Output is maintained until overwritten with the next output data.
2) In case output data is written into a unit address which has been set as an input, the written data is
ignored and input data is set after 1 or 2 refresh times.
In case [Bank change-over response register = 01H] (S-LINK V I/O unit connection address)
The first address of S-LINK V I/O units connected on the S-LINK V system main cable is
shown.
When each bit is “1,” the
S-LINK V I/O unit having the set address is connected on the main
cable.
Note: When an S-LINK V I/O unit has several I/Os, only the bit corresponding to the rst address of that unit
is “1.”
In case [Bank change-over response register = 02H] (Error 3 occurred address)
When Error 3 occurs, the rst address of the affected S-LINK V I/O unit is indicated.
When each bit is “1,” the
S-LINK V I/O unit having the allocated address has a cable break or
the I/O unit is in abnormal condition.
In case [Bank change-over response register = 03H] (Error 4 occurred address)
When Error 4 occurs, the rst address of the affected S-LINK V I/O unit is indicated.
When each bit is “1,” an unidenti ed unit exists at the S-LINK V I/O unit having the allocated
address.
In case [Bank change-over response register = 04H] (Error 5 occurred address)
When Error 5 occurs, the rst address of the affected S-LINK V I/O unit is indicated.
When each bit is “1,” an output short-circuit of an output unit or shut down of I/O drive power
supply has occurred at the
S-LINK V output unit having the allocated address.
In case [Bank change-over response register = 05H] (Occupied address)
The addresses allocated to the recognized S-LINK V units are indicated.
When each bit is “1,” the address is being used for an
S-LINK V I/O unit.
In case [Bank change-over response register = 06H] (I/O state)
This shows whether the recognized S-LINK V system address is being used as “Input” or “Output.”
The address is uesd as “Input” if the address corresponding to each bit is “1,” and as “Output” if
the address is “0.” (Unused address is “0.”)
In case [Bank change-over response register = 07H] (Interruption setting)
It shows the address of S-LINK V I/O unit set for interruption processing.
The interruption process setting is carried out in units of one channel.
When each bit is “1,” the interruption occurs when the signal of the
S-LINK V input having the
allocated address changes. (In case the resource generating the interruption is set.)

bit 0 to 3: Occurred error No. is displayed. (0H to 6H)
bit 7 : The error state is indicated.
Notes: 1) Error 0 is not automatically restored. (In case bit 7 is “1” and bit 0 to 3 is “0H,” Error “0” occurs.)
2) If Error 1, 2, and 3 to 6 occur at the same time, Error 1 and 2 are given priority in error indication.
3) For Error 1 to 6, in case the cause of the error is eliminated, although bit “7” becomes “0,” the error
No. indication of bit 0 to 3 is maintained.

6) HML0 + 49: Command execution request register
7) HML0 + 4A: Command completion response register (read out only)
bit 0: “Communication frame con rmation indication”
It is used for checking if the output data is sent to S-LINK V output unit.
In case data is sent to the same address at an interval shorter than the
S-LINK V system
response delay time, the data may not be transmitted. After the output data is written, if “1”
is written into HML0 + 49 bit 0, and the next output data is written in after con rming that
HML0 + 4A bit 0 has turned to “1,” then output data transmission error can be avoided.
bit 1: “Error No. clear”
It clears the error No. in case the cause of error has been eliminated at “
5) HML0 + 48: Er-
ror No. / Error state ” in “ 4. Assignment on computer ” and when HML0 + 48 bit 7 is “0.” If
“1” is written into HML0 + 49 bit 1, HML0 + 4A bit 1 turns to “1” after the error No. is cleared.
bit 2: “Default”
After “1” is written in, all the setting items are set to the initial conditions (Transmission
mode: A mode, I/O control numbers: 512) by reset (HML0 + 4D), and the address informa-
tion of the recognized units is cleared. If “1” is written into HML0 + 49 bit 2, HML0 + 4A bit 2
turns to “1” after the completion of the default setting. Then, execute the reset (HML0 + 4D).
These are used to indicate Communication frame con rmation, Error No. clearance, Default, Sys-
tem set, Interruption, Busy, On Hold and command under execution.

bit 3: “System set”
It reads in the
S-LINK V I/O unit connection state at that time. If “1” is written into HML0 +
49 bit 3, HML0 + 4A bit 3 turns to “1” after the completion of system setting.
bit 4: “Interruption indication”
In case interruption has occurred, HML0 + 4A bit 4 turns to “1.” In order to clear this, write
“1” into HML0 + 49 bit 4 to execute, and the clearance is completed when HML0 + 4A bit 4
turns to “0.” In case “0” is written into HML0 + 49 bit 4, it is ignored. After the clearance, in
case HML0 + 49 bit 4 does not return to “0,” it will be cleared soon after the next interruption
occurs.
bit 5: “Busy indication”
When the Busy indicator lights up, such as during system setting, “1” is indicated in HML0 +
4A bit 5. After the Busy state is over, it turns to “0.“
Even if written into HML0 + 49 bit 5, this will be ignored.
bit 6: “On Hold indication”
In case the input hold is effective (HML0 + 4E bit 0 is “1”), the current state is indicated with
Hold “1” or the state before Hold with “0.” When Hold cancel (HML0 + 4E bit 0 is “0”) is set,
it returns to “0.”
bit 7: “Command under execution indication”
After the receipt of each command of HML0 + 49 bit 0 to 4, HML0 + 4A bit 7 turns to “1” until
the command completion. When the command execution is completed, it turns to “0.” This
bit allows you to check if a command has been received.
Notes: 1) Once each command of bit 0 to 4 is executed, the bit value does not return to the original value.
In order to execute the next command, write “0” into the bit corresponding to HML0 + 49 once and
check that the bit corresponding to HML0 + 4A has turns to “0” prior to the execution.
2) “System set” and “Command” cannot be executed during an interruption occurrence. Only clear-
ance of the interruption can be carried out.
8) HML0 + 4B: Bank change-over request register
9) HML0 + 4C: Bank change-over response register (read out only)
These are used when changing the bank of “ 1) HML0 + 00 to HML0 + 3F: Data area .”
First, write a value (“00H to 07H”) in “
8) HML0 + 4B: Bank change-over request register ”
through the computer.
After 1 to 2 refresh times, the control board changes over the bank of, “
1) HML0 + 00 to HML0 +
3F: Data area
” and writes the changed bank number in “ 9) HML0 + 4C: Bank change-over re-
sponse register
.” (Refer to “ 1) HML0 + 00 to HML0 + 3F: Data area ” for the procedure.)
Notes: 1) In case a number other than “00H” to “07H” is written in “ 8) HML0 + 4B: Bank change-over re-
quest register
,” it compulsorily changes bank as “00H.”
2) Do not read out / write in “
1) HML0 + 00 to HML0 + 3F: Data area ” until “ 9) HML0 + 4C: Bank
change-over response register
” has been changed over.
10) HML0 + 4D: Transmission stop / Reset
In order to stop the transmission of S-LINK V system, write “0FH” into HML0 + 4D. In order to
restart it, write in the reset command.
This resets the
S-LINK V system. (In case I/O setting has been changed at “ 4) I/O setting
switch (SW3, SW4) ” in “ 3. Functional Description ,” the change is re ected.) If “1EH” is writ-
ten in HML0 + 4D, I/O data is cleared and then reset. In case “2DH” is written, I/O data is held
and then reset. In case a value other than these is written, it is ignored.
Even if the transmission mode or I/O control number is changed, the setting is not changed with
this reset command.

11) HML0 + 4E: Input hold / Input change interruption / Input change interruption /
Occurrence condition / Error interruption
bit 1: “Input change interruption” sets whether an interruption occurs or not when the input signal
changes. In case bit 1 is “1” an interruption occurs, and in case it is “0,” an interruption does
not occur. If the input change interruption is effective, an interruption occurs when the input
signal of
S-LINK V input address set as “1” at “Bank change-over response register = 07H”
changes.
bit 2: “Occurrence condition for input change interruption” sets whether the interruption occurs
with “1: ON OFF” or “0: OFF ON,” when bit 1 is “1.”
bit
76543210
Assignment
Input hold (1: Hold, 0: Hold cancel)
Input change interruption (1: Effective, 0: Ineffective)
Occurrence condition for input change interruption (1: ON OFF, 0: OFF ON)
Error interruption (1: Effective, 0: Ineffective)
Unused
(= 0)
bit 0: If the input signal is changed, “Input hold” selects whether the changed condition is main-
tained or not. (Usable for
S-LINK V address 0 to 7 only. However, if hold is used at one
address, then all 0 to 7 are held.) If bit 0 is “1,” even when the input signal is changed, the
condition is maintained until “0” is written in bit 0. After “0” has been written in bit 0, normal
transmission is resumed.
Note: Occurrence condition for input change interruption is applied to all input interruptions.
(However, it cannot be selected in units of one channel.)

5. INTENDED PRODUCTS FOR CE MARKING
The models listed under “ 6. Speci cations ” come with CE Marking.
As for all other models, please contact our of ce.
Be sure to meet condition 1). Furthermore, either condition 2) or 3) should also be met.
1) Cable length between the main power supply and the controller should be less than 10m.
2) When the power is supplied from S-LINK V controller to I/O devices at a cable distance of more
than 10m, add a surge absorber between 24V and 0V at a cable distance of less than 10m.
Recommended surge absorber: ERZ05D390 (Manufactured by Matsushita Electronic Compo-
nents Co., Ltd.)
3) Use a local power supply at a cable distance of less than 10m from each I/O device.
[Conditions in use for CE conformity]
Note: Do not connect a surge absorber between D and G.
Conditions
bit 3: “Error interruption” sets whether an interruption occurs or not when an error occurs.
When bit 3 is “1” an interruption occurs, and when bit 3 is “0” the interruption does not oc-
cur.
In case the error interruption is set to effective, the interruption occurs with OR operation
applied to all error occurrences.
For contents of error, check by “
5) HML0 + 48: Error No. / Error state .“
Note: In case bit 2 (Input change interruption) and bit 3 (Error interruption) are both “1,” bit 3 (Error interrup-
tion) has priority. Input change interruption does not occur.
