Hi Wizard,

I attached a screenshot with the installed software details.

Hi billbolbol,

Ok, you are using the latest software version.

Then I would advice to start a Support Request

ps. Let us know the result.

Best regards,

Wizard

Hello Billbolbol,

As i have said in other topics, I think this topic has been discussed plenty of times.

As far as iI know, and because i experienced it as well, you are use lasted (or 4.x or higher) PID control version. In TIA PORTAL (using S7-PLCSIM V13) you cannot simulate those PID versions (any of them: Compact, TEMP or 3Step V2.x) in a S7-1200. You NEED to downgrade your PID Control version to v3.x (or compact v1.x).

For further information, you can check this two links:

Why PID_Compact doesnt work

PID Problem

Both of them explain why the PID control doesn't work when being simulated, also explain how to change PID version for simulation propouses.

Hope it helps.

Regards,

Javier

Hello Jav Pinz,

Thanks for your answer, could you please tell me how to downgrade the PID version because the attached links don't show that.

 Hello Billlbolbol

For changing PID Control Version, follow the next steps:

Go to Technology/PID Control/Compact PID and the click on version (it appear V5.0 - v4.0- v3.0..... and choose v3.0), It will allow you use only Compact V1.2 and 3step, but the PID_Compact works similitar to PID_TEMP and PID Compact V2.2.

Be aware of how use the instructions, because some of the change the way how are called, but theres no difficult.

If you have any doubt, jus post it.

I Add and Img with the process =P

Hi Jay,

 I changed the PID version as you described and ended up with over fifty warnings. It took hours to correct 16 tags and I am not inclined to spend the next week fixing the rest.

What did you mean by "no difficult" what tricks do you know?

Thanks

Kal

Hello Kal.A

What i did my very first time changing the tags was having a copy in a S7-1500 (as you know, in 1500 it works perfect). For that, I read which things are different between V3 and V4 upper using help window of TP.

For example, When you want to change a PID state, you only need to do the next rutine in V4-5:

For PID V3:

"PID_Compact_1".sRet.i_Mode := 4;

This is not a IN parametre, is a static or special parametre.

In the direction of ""PID_Compact_1".sRet." there are some of the direct parametres that you active. Also some names change, like "output" and "output_heat", or "sParamCalc.i_Event_SUT" and "PIDSelfTune.SUT.State".

In my Code, I did not spend many time changing tags, but i did a fast read before starting, and then just compare.

If you need any Help, just tell me here or via PM.

Regards,

Javier

Thanks Jav.

It took me hours (well may be over an hour) to change the few tags in PLC program when I downgraded the PID version because the old version had non sensical tag names like:

PID_Compact_1.CycleTIme.Value in the new version is PID_Compact_1.sPid_Calc.r_Cycle

And that was a easy example. Most of them were nightmarish and the only way to recognize them was by matching the German comments from one version to the other as the comments were the same!!!!

Changing to S7-1500 required no tag renaming at all.

Thanks
