Temperature Reading using IDEC

Hello,
I am working on a project where I have to record the temperature reading for 4 ethylene glycol solutions using 4 K-Type Thermocouple connected to Analog card.

Currently, I started with one thermocouple. (I am new to PLC and have been reading about it since last week. I do have programming background which made easy to me).

Now,
I have set it all up and connected:

1) PLC FC5A-D12K1E from IDEC
2) HG3G Multi colored HMI screen
3) Analog Card FC4A-J4CN1

The set up is shown in picture: Temperature Measurement.jpg

Then I wrote a ladder diagram as shown in Ladder Code.jpg (The M 0014 code is just to see it download and working. I dont need it for temperature reading)


Later, I created a base screen as shown in Base SCreen.jpg. I gave the device address that is mentioned in Analog card of the Ladder Code.


Also, All my goal was to read a temperature from 1 Thermocouple-K Type, which is connected to Analog Card (FC4A-J4CN1).

After downloading Ladder code to PLC and the Base Screen to HG3G, I pressed start button on the HG3G to see if its working.
It did not read anything on numerical display but after few seconds I got an error "Host Communication error"

Do I have to give power to Analog card(FC4A-J4CN1) even though I have connected it to PLC (FC5A-D12K1E)?

Or is there anything I am missing in Ladder diagram?


It has been two days I have been working on this error and have not got any far.

You should try and break down the problem in smaller steps:
Analog Card Communication:
http://www.idec.de/produkte/-handbuecher/sps/MicroSmart/Englisch/FC5A-Manual_Advanced_FC9Y-B1273-2.pdf
In this advanced manual it shows the wiring diagram for the analog. (Search for PID Example)

Screen to PLC:
Are there communication lights on both units indicating communication is happening?

Hope this helps,

"Host Communication error" is the Screen not communicating with the PLC.

Make sure you have the driver configured correctly in the Screen software.

gclshortt and swimmy67,

Thanks for your help guys.

I did not give power to Analog card.

Also, swimmy07 you were correct on the screen not communicating with PLC.





Thanks for your help guys.

Now I am on next stage of figuring out how to record the temperatures. I have to go back to ladder program.






Any advice would be a great help.

Thank you again
