S5135 U problem

[rgua]

please forget my post #12, not inherent.

OB1 / segment 1
0003 DBA1 :  DB 40             // assign 40 to param. DBA1
0006 ADR. :  KF +160           // assign 160 to param. ADR.

FB65
0021      :B   =DBA1      // open DB40 data block
Segment  2
002E      :LW  =ADR.      // Load ADR. parameter, 160
002F      :T   FW 252     // store to FW252
0030      :I        2     // increase + 2, then 162
0031      :T   FW 250     // store to FW250 word: FW250 = 162
........
004C      :DO  FW 250     // indirect addressing: using FW250 data, 162
004D      :L   PW   0     // load peripherie L PW 162
004E      :T   DW 100     // store to DW100 of DB40

what is PW162 input? try to insert an L PW 162 in OB1 as first instruction.

Dear Sir
You mean i have to modify the OB1 only as pdf attached

Have you performed an overall reset?

Procedure:

1. Hold Down bottom toggle switch
2. Switch from stop to run twice
3. Stop LED flashes regualr frequancy
4. Keep bottom toggle switch held until stop light stops flashing
5. Place in Run

The try re-downloading the program.

yes, for test purpose only.

Dear Sir
I have erased program using this procedure around 50 time
no use

Can you please use the compare function in the S5 Software.
Compare the program on the computer with the program in the PLC
Please report any errors.

 

[nehe bhimaji]

Yes
I will compair and inform

Hi!

As far as I can remember, the I-STACK stepcounter points to the step after the error line. If I remember right, does this mean that it's the load command that makes your plc stop. You have to check your input area more closely.

But sir
according to I stack what is exact input that have stop CPU?

L PW 162.
The cpu stops in FB65 at relative address 004D. This is the first PW reading in your program. The "L PW 162" is an immediate reading for fast resposnse.
I think your PW inputs are for encoder reading. If you have an encoder reading card as IP240 or similar card, your cpu can't read that card.

Here is a link to the operations list for the 135U/155U cpus.
At the end of the document you will find the MC5 - codes.
If you compare the OP-REG with the MC5 codes you can find out what
stopped the CPU.

Thanks
Problem is solved peoblem was in encoder card
