1. INTRODUCTION

Thank you very much for using Panasonic products. Please read this Instruction Manual

carefully and thoroughly for the correct and optimum use of this product. Kindly keep this manual

in a convenient place for quick reference.

2. CAUTIONS

POWER SUPPLY

zPeriodically check voltage fluctuation to ensure that it does not exceed the rated voltage. Also

check the voltage fluctuation at the end terminal of the transmission route, since voltage drop

occurs depending on the diameter or the length of the transmission cable.

zIf 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.

zDo not use during the initial transient time (0.5 sec. approx.) after the power supply is

switched on.

zMake sure to use an isolation transformer for the DC power supply. If an auto-transformer

(single winding transformer) is used, this product or the power supply may get damaged.

zIn case a surge is generated in the used power supply, connect a surge absorber to the supply

and absorb the surge.

WIRING

zDo 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.

zMake sure that the power is off while wiring.

zIn order to reduce noise, make the wiring as short as possible.

zAlways use the specified transmission cable.

ENVIRONMENT

zThis product has been developed / produced for industrial use only.

zIn case noise generating equipment (switching regulator, inverter motor, etc.) is used in the

vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual

ground.

zThis product does not have a dustproof or waterproof construction. Do not use it in places

having excessive vapor, dust, etc., or where it may come in direct contact with water,

chemicals or corrosive gas.

zDo not use the product in places where the ambient temperature or humidity exceeds the

specifications.

OTHERS

zPlease refer to the S-LINK Users’ Manual for the details of system design.

zAny protection or safety circuits against system malfunction should be designed to be external

to the S-LINK system.

ճMode switch

Perform setting of the S-LINK system. I/O SET 0 to 3 are for setting input / output. SA 0 and SA 1

are for setting the number of input / output points.

Setting is read in only once when power is supplied to PC/AT. Changing the mode switch setting

during operation is ineffective.

մSystem set button

Press the system set button to read and memorize the connection condition of S-LINK I/O

devices. Later, it is possible to check abnormality using this as the basis.

Note: If you press the system set button when ERROR 4 occurs, the error is released. However, if the cause

of the error is not rectified, the error address is, from now on, missed out from the checked items.

(This address is treated as unconnected.)

յTransmission indicator (Green)

It blinks when communicating I/O data with S-LINK I/O devices.

(Normal condition: blinking, abnormal condition: off)

նError indicator (Red)

It lights up when an error occurs on the S-LINK system main / branch cable.

Notes: 1) When ERROR 1 alone occurs, the short-circuit protection between D-G is operative. Release the

short-circuit protection function by rectifying the cause of the fault after switching off external

power supply. (The short-circuit protection function is maintained during the period in which the

power supply is on.)

2) ERROR 1, 3 light up when the external power supply is off.

3) ERROR 4 is held on. It can be released by supplying power either to the S-LINK system side or to

the personal computer PC/AT once again. Although release can also be obtained by pressing ‘մ

System set button’, in this case, refer to the note given in ‘3. FUNCTIONAL DESCRIPTION’.

In case ‘Bank change-over response register = 00H’ (Initial value)

This is an area to read out input data and write in output data of S-LINK I/O units.

In case of input, ‘0: Input OFF’ or ‘1: Input ON’ is read out in each bit.

In case of output, write in ‘0: Output OFF’ or ‘1: Output ON’ in each bit.

Notes: 1) Output data is saved until you overwrite with the next output data.

2) In case output data is mistakenly written into an input unit, the written data is ignored and new

input data is set after 1.4 to 10.7 ms.

In case ‘Bank change-over response register = 01H’

It shows the addresses of S-LINK I/O units at which ERROR 4 has occurred.

When a bit is ‘1’, ERROR 4 (cable disconnection or abnormal S-LINK I/O unit) has occurred

at the S-LINK I/O unit having that address.

Note: Addresses of units where ERROR 4 occurs is held on. ERROR 4 can be released (‘0’) by supplying

power either to the S-LINK system side or to the personal computer PC/AT once again. Although

release can also be obtained by pressing ‘System set button’, in this case, refer to the note given in ‘3.

FUNCTIONAL DESCRIPTION’.

In case ‘Bank change-over response register = 02H’

It shows the addresses of the S-LINK I/O units connected on the S-LINK system main /

branch cables. When a bit is ‘1’, an S-LINK I/O unit is connected at that address.

Note: When an S-LINK unit has several I/O devices connected to it, only the bit corresponding to the first

address of that unit is set to ‘1’.

In case ‘Bank change-over response register = 03H’

SL-PCAT product information (version number) is registered in ASCII code.

ղ(HML+1) 0: Flag

It indicates the operation condition of the S-LINK system.

R/W Function

bit 5

㸫

Unusable (= 0)

bit 4 R S-LINK system communication status (1: Under communication)

bit 3 R ERROR 4 (1: Wire disconnection or abnormal I/O unit)

bit 2 R ERROR 3 (1: Abnormal voltage level between D and G)

bit 1

㸫

Unusable (= 0)

bit 0 R ERROR 1 (1: Short circuit between D and G)

(‘R/W’ ЍRead out / Write in, ‘R’ ЍRead out)

bit 0 to 3 : ‘ERROR 1, 3 and ERROR 4’ are ‘1’ when the respective error occurs.

bit 4 : It is ‘1’ when communicating with the S-LINK I/O units.

bit 6 : It has the same operation as ‘System set button’.

When ‘1’ is written, the connection condition of the S-LINK I/O units at that time is

read. It automatically returns to ‘0’ after the reading.

bit 7 : In case of sending different outputs to the same address, the former output data

will be ignored if the next output data is written in before the former output data

has been transmitted to the S-LINK output unit.

‘Confirmation of communication frame completion’ is used to confirm whether the

output data has been transmitted to the S-LINK output unit.

When writing in numbers other than ‘0’ after writing in output data, it automatically

returns to ‘0’ after transmitting the output data to the S-LINK output unit. So,

transmission error of output data will be prevented if you write in the next output

data after its returning to ‘0’ is confirmed by the program.

Notes: 1) ERROR 1, 3 are held on until the cause of the error is removed.

2) ERROR 4 can be released (‘0’) by supplying power either to the S-LINK system side or to the

personal computer PC/AT once again. Although release can also be obtained by pressing ‘System

set button’, in this case, refer to the note given in ‘3. FUNCTIONAL DESCRIPTION’.

ճ(HML+1) 1: Number of connected S-LINK I/O units / First address of units

where ERROR 4 occurs

Under normal condition: It indicates the number of connected S-LINK I/O units.

bit Assignment

7 to 0 Normal: Number of connected S-LINK I/O units 1 to 128

(In hexadecimal number system, 01H to 80H)

Note: When the same address is set for several S-LINK I/O units, they are regarded as one unit.

Under ERROR 4 condition: It indicates the first addresses of S-LINK I/O units where

ERROR 4 has occurred.

In case ERROR 4 occurs at several address, bit7 = ‘1’.

bit Assignment

7 1: ERROR 4 occurs at several units (in case the number of units with ERROR 4 = 1, bit = ‘0’)

6 to 0 Under ERROR 4 condition: First addresses of S-LINK units with ERROR 4 (0 to 127)

(In hexadecimal number system: 00H to 7FH)

Note: ‘First address of units with ERROR 4’ is held on. ERROR 4 can be released (‘0’) by supplying power

either to the S-LINK system side or to the personal computer PC/AT once again. Although release can

also be obtained by pressing ‘System set button’, in this case, refer to the note given in ‘3. FUNCTIONAL

DESCRIPTION’.

մ(HML+1) 2: I/O setup of SL-PCAT

It sets up or indicates the I/O assignment of SL-PCAT.

Immediately after power supply or reset of personal computer PC/AT, it indicates the setup

condition of ‘Mode switch’.

When setting I/O by programming, put all I/O setting switches to ‘0’: ON and then write in.

bit Assignment

7S-LINK address 112 to 127 I/O setup (0: Input, 1: Output)

6S-LINK address 96 to 111 I/O setup (0: Input, 1: Output)

5S-LINK address 80 to 95 I/O setup (0: Input, 1: Output)

4S-LINK address 64 to 79 I/O setup (0: Input, 1: Output)

1S-LINK address 16 to 31 I/O setup (0: Input, 1: Output)

0S-LINK address 0 to 15 I/O setup (0: Input, 1: Output)

յ(HML+1) 4: Bank change-over request register

ն(HML+1) 5: Bank change-over response register

It is used for bank change-over of ‘ձ(HML) 0 to (HML) F’.

First of all, write in the number (‘00H’ to ’03H’) into ‘յ(HML+1) 4: Bank change-over request

Then, 1.4 to 21.4 ms later, SL-PCAT changes over bank of ‘ձ(HML) 0 to (HML) F’, and writes

in the changed bank number (‘00H’ to ’03H’) into ‘ն(HML+1) 5: Bank change-over response

Notes: 1) In case a number other than ‘00H to 03H’ is written into ‘յ(HML+1) 4: Bank change-over

request register’, it compulsorily changes over bank to ‘00H’. The output data is stored till the

new output data is next written.

2) Do not read out ‘ձ(HML) 0 to (HML) F’ until ‘ն(HML+1) 5: Bank change-over response

registe’ has been changed over.

շ(HML+1) 6: System set

It has the same operation as bit 6 : system set button of ‘ղ(HML+1) 0: Flag’.

When a number other than ‘00H’ is written, the S-LINK I/O unit addresses at that time are read.

It automatically returns to ‘00H’ after reading.

ո(HML+1) 7: Frame check

It has the same operation as bit 7: frame check of ‘ղ(HML+1) 0: Flag’.

In case of sending different outputs to the same address, the former output data will be ignored if

the next output data is written in before the former output data has been transmitted to the

S-LINK output unit.

‘Frame check’ is used to confirm whether the output data has been transmitted to the S-LINK

output unit.

When writing in numbers other than ‘0’ after writing in output data, it automatically returns to ‘0’

after the output data is transmitted to the S-LINK output unit. So, transmission error of output

data will be prevented if you write in the next output data after its returning to ‘0’ is confirmed by

the program.

չ(HML+1) 8: Number of S-LINK I/O units where ERROR 4 has occurred

It indicates the number of S-LINK I/O units where ERROR 4 has occurred.

ERROR 4 can be released (‘0’) by supplying power either to the S-LINK system side or to the

personal computer PC/AT once again. Although release can also be obtained by pressing ‘System

set button’, in this case, refer to the note given in ‘3. FUNCTIONAL DESCRIPTION’.

պ(HML+1) 9: Number of connected S-LINK I/O units

It indicates the number of connected S-LINK I/O units.

ջ(HML+1) A: Number of I/O points

It indicates the number of I/O points set by ‘Mode switch’ (SA 0 and SA 1).

One of the numerical values 32, 64, 96 or 128 is indicated.

ռ(HML+1) B: Address of SL-BS1A where operation stops
