Heu... It was me upside

It still doesn't work.... The output of the PID doesn't changes whatever be the mesure or the set point... I send you the .cpx file. Maybe someone could find the error I remplace all symbols W by symbol H. H200 and H250=&3 r_gul_moteur4.cxp

Thank you Sleepy Wombat Omron should learn how to make a programtion guide, cause in the guide I have, it's not APR but ARP written... It shouldn't work -_- But, il fact, I forgot that the values should be between 0 and 100%... Now, I've got 2 days to finish this project, thanks for your help ^^

I think too ^^; I use theese symbols : W10 to W14 W100 and W101 W1 W20 is the word C f the PID instruction W102 <== Although it would be contant, it changes... My PID instructions' values : C+1 : 10 (temporary) C+2 : 9999 (temporary) C+3 : 0 (temporary) C+4 : 1 (int) C+5 : 000B (Hex) All bits are forced C+6 : +6281 (int) Bits 12,11,7,3 and 0 are forced on Bits 1 and 2 are forced to off Other bits are off but not forced C+7 : -1500 (its the minimum that the process accepts) C+8 : +1500 I've tried to change the value of SP, but it's fixed to 0, and and can't change it (as all PID values : G, Ti, Td....) But, with the SP at 0 and the mesure is at 1000 and the output of the pid instruction doesn't changes... (I tried with values under 100, and I have the same results...) When I send the program to the API, I've got those advertisings messages : * Sortie **** is duplicated * The symbol SP has a data type (int) which is not compatible with the data's operand (DINT) (This my traductions, maybe there are not good at 100%) The input and output are ok when I'm not in auto (in regulation) but maybe you'll be interested by this : I use devicenet modules. I have this configuration : output : node 01. pins 1,2,4,5, and 8 are on. Only the first channel is connected input : node 00. pins 1,2,4,5 and 8 are on. Only the first channel is connected I hope I sent you the good informations

Hello I'm studiant and I have this project to do : To control an "engine with DC current" with the PID function of the CJ1M CPU22 automate. But, the function doesn't work... But I have configured the words C to C+9 as written in the documentation... I have tested the acquisition of mesure and the command of the engine, and all is ok. That's why I think the problem comes from the PID And I would like to manipulate words in my programation (with du function MOV), so I used the "W" caracter, is it the good symbol ? I saw I can change the caracteristics of this symbol (dint, int, channel....). When I send the program to my API I have the message Error which say that my data are not compatibles (dint and int for example). So I tried to change their caracteristics, but it doesn't work for some words... Do I use the best method to manipulates words ? If not, which is the best one ? If yes how can I change the caracteristics of the variables ? Thank you and excuse me for my English ^^;
