I'm newbie in PLC and I face couple problem in SCL(194) instruction.

The problem have wrote to the pictures kindly tutorial me how to do it!

The link above is the CX-Programmer Introduction Guide.

In the guide it will show you how to monitor the DM area and make modifications. Off line just click on the memory and then call the DM area up.

Hope this helps you,

Not problem bro!

Thanks ur pictures that helping me understand how to use SCL(194).
But I still confuse couple things.

I)The SCL(194) instruction is hex value convert to bcd value?
II)D122 & D123 is limit the maximal and D120 & D121 is limit the minimal?
II)How to use SCL(194) to read encoder motor?


Thanks in advance

The above thread shows an example of the scaling function.

The following are your answers:
1 - The SCL(194) instruction is hex value input converted to a bcd value based upon a linear scale.
2 - D122 & D123 is limit the maximal and D120 & D121 is limit the minimal. Not exactly. These values will determine the linear scale. We define the two points on the scale to represent a straight line. They just have to be two points.
3 - How to use SCL(194) to read encoder motor - This will depend on the value of the encoder. Is it BCD or Binary? If Binary (Hex) then use the instruction as is. If BCD then use the BIN(23) BCD to Binary to convert the number first.
This would apply to the output as well.
The output is in BCD. If you want Binary (Hex) then use the BIN(23) instruction again.

3-17-7 SCALING: SCL(194) of the manual above will give you a picture of the scaling function.

appreciate for tutorial me!

I still have few questions confused.

I) The analog signal to plc, so the value is #0000 to #0FA0, right?
II) If yes, SCL(194) D100 which only can read #0000 until #0FA0, right?



Thanks in advance

The both pdf files are same!

I)In the ladder diagram at rung 1 why MOV(21) need transfer date from D22 to D24

II) Ignore my silly question, why P1+2 and P1+3 must specify #1000 and #0FA0?


Thanks in advance

i will give an example,

if i buy a car i will check the car spec

the price,engine CC,torque,gas consumption,tire spec and etc,

it's also apply to plc,what the capability of the plc you must take note,

if #0000 to #0FA0 (0-4000) are apply to CP1L ,maybe this same apply to 1300cc car engine,

if #0000 to #1F40 (0-8000) are apply to another omron PLC probaly 1600cc car engine,


if the car are tune for 1300cc for fuel injection you can't use 1600cc fuel injection spec.

check the spec

must always refer to manual

why D22 TO D24 ?

why #1000 and # 0FA0 ?

because this only example looh.

change any value see what happen

Respecter of my sifu!

I totally understood how to use it.
Could you send for me that omron plc manual book which you upload couple page only.
