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:

CAP505 - Master Design View window

Open project window by CAP505

2. Run „Relay Configuration Tool“:

Main window

Type password “ABB”:

Requiested password ABB

 

3. Select REF543 and open „Properties“ window:

REF543

CAP505 properties

 

4. By clicking “Settings”, open “Configuration of REF543” window:

Configuration of REF543
5. Select „Analog Channels“, and set currents, voltages channels, their parameters as shown in pictures:

Configuring REF543
To define analogues channels use this principle scheme:

Cheme CAP505
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:

Current Transformer 1

 

Press OK.
Select again „Channel 2” and click „Measurements“. Select „True RMS current“:

Special Measurements

 

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:

Voltage Transformer 2

Press OK.
Define channels Channel 9, Channel 10 in the same manner.

Select „Channel 4” and press „Measurements“. Select „True RMS current“:
Special Measurements

8. Now define current channel 5. Select „Channel 5” and press „Technical Data“. In „Current Transformer4” window type data as shown in picture:

Configuraion of REF543

Current Transformer 4

9. Now define voltage channel 7. Select „Channel 7” and press „Technical Data“. In „Voltage Transformer1” window type 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.
