I like your project
I have been working with Siemens PLCs for more than 6 years and where I currently have many liquid temperature controls.
I have some questions:
* Where can I read all the details of the project?
* Only I must elaborate the program of the PLC and indicate the variables to use in the Scada so that who realizes the development of scada executes the adaptation?
* What model of PLC will be used, it is necessary to know all the Hardware to use.
* Any specific address for the PLC IP?
* Assuming all tanks are at the indicated temperature (SP), in addition to closing the valve of each tank, should the chiller be turned off?
* The temperature deviation values to generate the alarm will be received directly from the Scada?
* Could send a diagram of the connection of the chiller, pipes, valves and tanks. You do not need a P & ID, but a basic outline.
With all the required information, the program can be ready in less than 7 days.
Best regards
