How to control Eurotherm 2216e with LabView?

[jolykj]

Hi outhere

I have 2 off these Eurotherm 2216e i want to control with labview, as the rest of my set up is run by labview. I am unsure about a lot of things regarding the Eurotherm 2216e, and reading the manual https://www.eurotherm.com/?wpdmdl=26675 doesn't help me a lot.

I am going to use the 2216e to heat up units to different temperatures and to get the temperatures of the units.

I see there is 4 ways to connect the a 2216e to a computer, but i am not sure what there is best for my needs?

4-wire EIA-422 serial communications

EIA-232 serial communications

PDS Setpoint input (SST)

2-wire EIA-485 Serial Communications

I am also not sure how to get/set the temperature from the 2216e, as i can't find a command list, but it might be me reading the manual wrong.

Any help and/or examples would be greatly appreciated, as i am new to the control of 2216e/ pid controllers.

Did you even try to search the forum before asking your question?

Yes i did see this one, but it doesn't really answer my first question about how to connect the pc to the 2216e, except the user uses rs-232.

As there are 4 types of inputs an i have two 2216e i was hoping to see if any of the other input methods was better than rs-232.

Also that post is 15 years old, and maybe there has been some updates to both connection method and software.

But i appreciate the input.

They are all a possibility but have their specific requirements:

4-wire EIA-422 serial communications

You need a RS-422 compatible communication interface on your PC. Your VIs will need to be able to talk the binary protocol that allows individual device addressing. The Eurotherm 2416 driver from the Instrument Driver Network also supports your 2216 device, although you won't be able to use all of the VIs from that driver, since the 2216 is a more simple device that does not offer all the options of the 2416. Wiring can get a little tricky if you have no electrical engineering background and you need to terminate the bus on both sides properly.

EIA-232 serial communications

You can not connect 2 Eurotherms to the same RS-232 interface, so you need two RS-232 interfaces on your computer. Other than that the Eurotherm 2416 driver will work for this too.

PDS Setpoint input (SST)

You control the Eurotherm with analog signals. You would need some analog output hardware to set the setpoint of the controller and analog input hardware to read the current value.

2-wire EIA-485 Serial Communications

You need a RS-485 capable interface. Advantage is you only need to use 2 wires, other than that it is the same as the 422.

Hi rolfk
I do have a USB-6363 which should be able to deliver and receive the needed analog inputs and outputs. And as far as i understand i connect the PID HE and HF is to be connected to Analog + and - respectively (Eks pin 20 and 21) of the USB-6363.

But i am still in doubt of what i read and send to get and set the correct information on thermocouple and heater, connected to the PID.

Any help would still be greatly appreciated.
