XWorks PID Control for 3-Position Actuator

Dear Friends,

I have to control temperature control valve (2-way valve controlled by 3-position actuator).

Basically there will be 2 binary outputs, 1 BO for open command and 1 BO for close command.

There is a temperature setpoint and a temperature sensor as a reference to control the actuator.

Could anyone help me with blocks library or PID in XWorks CFC to control this 3-position valve?

Hello,

Hope this will shine some light at the situation.

Kind regards,

 Hi CJ,

Your solution worked like a charm!

Thanks for the support :)

Hi,

The answer will depend on the type of PX controller / IO module that you are using.

For TX-I/O modules - the process is fairly simple, and was discussed previously HERE. There are 2 attachments in this post that you can refer to.

However, if you are using a Compact controller and the on-board digital outputs, then you will need to add some software. Hopefully your XWorks installation has the libraries installed.

See attached as an example of where you can find the pre-defined solutions. Simply drag and drop the chart into your software. An important thing of course is to set the drive-times for the actuator you are using (which are highlighted on the 2 PWM blocks).

If you don't have the libraries installed, then simply re-create what's in the attached screen dump.

Regards,
