[Error with Pressure Loop PID Heating Element]

Thanks. Got it up and running 

[Error with Pressure Loop PID Heating Element]

this was the status from the pid

 

fixed the parameters in the pid for control/process value.

Control value to 0-1000

process value: 0-30 for pressure sensor range

 

will update if it starts working

Aim for the the program is to control the air pressure in an enclosed tank via a heating element. I'm assuming due to getting an error with the PID status instruction being false, the PID/Auto tune/PWM/heating element won't activate/start. Other than that, pretty lost on why the system isn't functioning. We've checked that all sensors are working.

@Joe Tauser I attempted to make the changes you suggested. Sorry If it still needs more work new to PLC/Unitronics/Visilogic. Please let me know if there's anything I need to fix

@Joe Tauser 

Thanks for the feedback. I will make some changes and reach back out. Do you think I should get rid of the temperature loop all together? 

[Pressure Control in a Tank]

@Joe Tauser

Focusing on pressure. Not using any fluids/steam. Just the enclosed air in the tank. Heating element 300w. Don't want to go higher than 15 psi in the tank

[Pressure Control in a Tank]

Hello, 

Wanted to get feedback on the project I'm working on.  I've attached what I have so far. SD portion still under construction

Overview: 

Controlling pressure with a heating element inside a tank utilizing PIDs

 

Specs:

PLC: V700

Snap on: V200-E3/4XB

AI:

Pressure Sensor: 0-145 psi/ 4-20ma

Temp Sensor PT100: -50-300 C

Question:

How should I implement the selector switch logic/code to choose between the pressure/temperature loop?

 

Feedback:

Auto tune parameters

Linearization Block

Overall Check of Program would be appreciated

[PT100 Set up and how to Display on HMI]

@kratmel No logic is needed to display the temperature reading on the HMI?

[PT100 Set up and how to Display on HMI]

 

Hello,

 

I was seeing if someone could post logic/code on how to get the temperature reading from the sensor and then how to display the reading onto the HMI.

 

Also, how to wire the sensor on the plc

Thanks!

[Hardware Configuration for Pressure Transducer]

Hello, New to using PLCs.

PLC: V700, V200-18-E3/4xb

 

https://www.amazon.com/dp/B0748BHLQL?ref_=cm_sw_r_cp_ud_dp_MPKEBK3VM6AV7174NC1Q

Pressure Transducer: 0-100psi

Output: 0.5V~4.5V linear voltage output. 0 psi outputs 0.5V, 50 psi outputs 2.5V, 100 psi outputs 4.5V.

 

I wanted to know how  would I setup the pressure transducer in the Hardware configuration....Analog Inputs...type...mode, as well as what settings to use for the linearization block.
