In this article I describe the configuration of communication settings for CAP505. After setting CAP505 and PC communication settings we can connect them with PLC REF543. Also I show how to connect PC with PLC, how to supply PLC REF543. This concept is also described in manufacturer ABB manual “CAP 505 Installation and Commissioning Manual 1MRS751901-MEN“. How to navigate on HMI of PLC REF543 see manufacturer’s manual “Protection & Control Terminals RE_54_ Operator Manual 1MRS750500-MUM“.
1. First check PC COM port number. Choose „My Computer>Properties“:
In “System Properties” windows select “Hardware” and press “Device Manager”:
In “Device Manager” window select “Ports(Com&LPT)”. My PC COM port number is 1:
To exit choose File>Exit.
Next step is to set up CAP505 communication settings.
2. Run CAP505 software. Select “System Tools>System Configuration”:
3. In “Serial Ports” window press „Add“:
4. Type COM port number. My PC’s COM1, so type number 1 in “Add serial port ” window:
5. Save setting as shown in picture:
6. In “System Configuration” window press “Yes”:
7. The same settings type in PC communication COM port 1 settings:
How to find PC’s COM1 port settings see in particle 1 of this article.
8. Check CAP505 communication settings. Choose „Edit>Object Properties“:
9. Check PLC’s communication settings:
- Press button „E“.
- By pressing buttons „down“, „up“ select title „Communication“.
- Press button „to the right“.
- By pressing buttons „down“, „up“ select title „SPA“.
- Press button „E“.
- By pressing buttons „down“, „up“ select title „SPA address“.
- Press button „E“.
- Type password „2“. Each time when you want to change settings you must type this password.
- Type number „1. This is SPA port number.
How to navigate on HMI see manufacturer’s manual “Protection & Control Terminals RE_54_ Operator Manual 1MRS750500-MUM“.
This number must be the same as in CAP 505 software in „SPA address“ defined number:
- Press button „E“.
- By pressing button „to the left“ return to PLC‘s REF543 “MAIN MENU” window and press button „E“.
Communication settings are set. In next article I show how to download configuration and settings to PLC REF543.
To connect to PLC REF54x series manufacturer’s ABB original cable 1MKC950001-2 is used:
Cable’s optical head and COM port interface:
Connect cable’s COM port interface to PC’s COM port interface:
Connect cable’s optical head to PLC optical interface:
PLC’s optical interface is below button “F”:
To download configuration and settings from PC to PLC, you need to supply PLC, for example with 220 V DC: connect positive lead „+“ to PLC‘s terminal X4.1-1 and negative lead “-“ – to terminal X4.1-2:
You can supply PLC also with 110 V DC or 230 V AC voltage (see manufacturer‘s ABB manual “ Feeder Terminal REF 54_ Technical Reference Manual, General 1MRS750527-MUM“). How to navigate on HMI of PLC REF543 see manufacturer’s manual “Protection & Control Terminals RE_54_ Operator Manual 1MRS750500-MUM“.
In next article I describe how to import to CAP505 and export from CAP505 existing file.
Do you know where can i buy the cable. 1MKC950001-2 Thank you.
Hello, Victor!
Try to contact at ABB department at your country or your region. They should explain how to order required cable.
If you have any questions, don’t hesitate – ask, I will help.

REM543 – Wrong password – how uzant / change my password?
when you try to disable protection on the REM543 with panel … show message … wrong password …. what to do?
all other REM543 use two passwords the first 3 – to go to the settings of the second …. 2 – to turn off protection … so that’s the second password (2) does not fit 🙁 what to do …. how to find / change the password. ..
Hello Oleksandr!
There is only one way: if you have existing configuration file of REM543, you can disable protection in this configuration file and then download changed configuration to PLC REM543.
How to read existing configuration from PLC, read article no.28 “Reading existing configuration from PLC REF543”.
Best regards, Rimvis
I have required Software communication cable (1MKC950001-2 9600-115K baud)
