How to configure PLC’s analogues channels, binary inputs, define their parameters?
This is the main scope of this article. When you have created project configuration tree, you should define current and voltage channels, transformers rates. How to create project configuration tree see article no.5 “CAP505 course of PLC REF543: 5. Creating project’s configuration tree with CAP505”.
More detail about PLC REF54x you can read in ABB manual ”Feeder terminal Product guide Version: H/25.10.2010”. About PLC REF54x configuration read in ABB manual ”Protection & Control Terminals REF 54_, REM 54_, RET 54_, REC 523 Configuration Guideline 1MRS750745-MUM”.
1. Open project:
2. Run „Relay Configuration Tool“:
Type password “ABB”:
3. Select REF543 and open „Properties“ window:
4. By clicking “Settings”, open “Configuration of REF543” window:
5. Select „Analog Channels“, and set currents, voltages channels, their parameters as shown in pictures:
To define analogues channels use this principle scheme:
You can connect currents to channels Ch2, Ch 3, Ch 4, Ch 5 (CT1, CT2, CT3, CT4, CT5). Here CT1 means current transformer. You must for each current channel select signal type: channels 2, 3, 4 are phases IL1, IL2, IL3. For channel 5 select zero sequence current Io. Channels Ch 7, Ch 8, Ch 9, Ch 10 (VT1, VT2, VT3, VT4) are used as voltages channels. Here VT1 means voltage transformer. Define channels Ch 8, Ch 9, Ch 10 as voltages U12, U23 and U31. Channel Ch 7 wil be used as open delta voltage Uo.
More detail about PLC REF54x you can read in ABB manual ”Feeder terminal Product guide Version: H/25.10.2010”.
6. Next step is to define current transformer’s rates. Select „Channel 2” and press „Technical Data“. In „Current Transformer1” window type data as shown in picture:
Press OK.
Select again „Channel 2” and click „Measurements“. Select „True RMS current“:
Define channels Channel 3, Channel 4 in the same manner.
7. Define voltage transformers rates. Select „Channel 8” and press „Technical Data“. In „Voltage Transformer 2” window type data as shown in picture:
Press OK.
Define channels Channel 9, Channel 10 in the same manner.
Select „Channel 4” and press „Measurements“. Select „True RMS current“:
8. Now define current channel 5. Select „Channel 5” and press „Technical Data“. In „Current Transformer4” window type data as shown in picture:
9. Now define voltage channel 7. Select „Channel 7” and press „Technical Data“. In „Voltage Transformer1” window type data as shown in picture:
10. In “Configuration of REF543” window “Virtual channels” ir “Conditioning Monitoring” leave parameters as defaults. Select “Binary inputs”, select data as shown in picture:
11. In “Configuration of REF543” window select “Measurements”, select data as shown in picture:
We finished setting analogues channels, binary inputs. Choose MAKE>Build Project to compile project.
In the next chapter we begin to work with measurements configuration using FBD programming language.

Hello ,sir
I’m second years student in Power system. I really like this field.Pleased explain for me what exactly Binary input mean? (why 0 and 1 high -low).I understand that for analog input is current and voltage .But in BI i cant get it .
Thank you so much !!
Hi Doan!
Purpose of analogue inputs are to measure currents, voltage, frequency.
Purpose of binary inputs are to understand state of circuit breakers, blocking signals, alarm signals.
In binary system there are only two digit: logical 0 or logical 1.
When voltage is aplied to binary input, binary input has state logical 1 (active state), for example circuit breaker is closed.
When voltage is not aplied to binary input, binary input has state logical 0 (not active state), for example circuit breaker is opened.
So state of binary inputs gives to terminal data about external world.
