DPIDE: Advanced PID algorithm for AH500 PLC

Delta AH500 PLC programming instructions for PID algorithm.

Instruction code: DPIDE (API 0708)

DPIDE Block description

Explanation of the DPIDE instruction:

The PID algorithm is implemented only when the instruction is executed.

PID  stands for Proportional, Integral, Derivative and is widely applied to mechanical, pneumatic and electronic equipment.

For a detailed explanation of DPIDE parameters, please refer to the following file: DPIDE Explanation

Application example:

Before the instruction DPIDE is executed, the setting of the parameters should be complete. When M1 is OFF, the MV is 0, and the MV is stored in D200. When X0.0 is switched OFF, the instruction is not executed, and the previous data is unchanged.

DPIDE Block example

The PID algorithm: When PID_MODE is set to 0 (false), the PID control mode is in automatic control mode.

When PID_MODE is set to 1 (true), the PID control mode is in automatic tuning mode. After the tuning of the parameters is completed, PID_MODE is set to o (false) automatically.

Announcement: New Application and Operation PLC manual

In the next weeks, we´ll release the new SV2, EH3, SE etc…
Some of you would remember the Es2 release 2 years ago. Today we can say that finally the renew of Delta S and E series, has been accomplished.
According to this, we decide to publish new manuals with the features of those new CPU´s.

We highly recommend updating your Delta PLC manuals in the following links
DVP-PLC Application Manual
DVP-ES2_EX2_SS2_SA2_SX2_SE Operation Manual

By the way, for the new and old readers don´t hesitate to visit our new Page PLC Tips&Tricks with a sum up of all the PLC related posts

PLC Instruction finder

Today I would like to publish a nice job from the technical team in the Delta Hungarian distributor Control Solution.
To show everybody how our partners can improve our documentation in their benefit.

Probably some of you spend a lot of time looking for the proper instruction and it´s relative example in the manual to check how to work with it.
Going page to page trying to find whatever you are looking for.

So to save this hard job to their customers Control Solution people just develop this simple on-line manual easily indexed using html file to find it.

You can link directly from here.
On-line Delta PLC Manual

I add this link on the blog pages to make the consult faster

Thank you Lajos!
