How to change the password of 800xAInstaller or 800xAService (Main) user names in System 800xA
Please contact your regional ABB support center to obtain instructions.
Depending on system configuration (eg activated options) the service account password is used on 10-20 different locations PER NODE. The configuration wizard covers roughly HALF of them.
Hence, after change of the service account password and update in wizard the system will become crippled and malfunction.
I could mention a few additional locations like eg the ABB Client License Service but I will not be able to remember them all by heart.
I strongly recommend asking for official help from your regional ABB team.
To somewhat counter the negative effects it is recommended to:
- Disable "Interactive Logon" for the service account (effectively restricting its use to run services only)
- Installer account is not critical; either disable it in between sessions when it is needed, or change password as desired.
System 800xA uses authenticated communication. Hence, do not change a password as long as the user is logged in and in need of the system. Changing the service account password may force the entire system down as a service might not be able to connect properly until the "password change team" has addressed that particular node. Hence, do not change the service account password while the system is in use.
Installer account:You can change the installer account password at any time even when system running since it acts as an admin for installation of system software.
Service account: is the one where all ur 800xa core services are running so changing password of this directly impact on the system causing down.
So generally it impacts cls, opc server and total system.
So if want to change the password list out the possible risks like plant data on hmi may block out.
Please involve regional support centre for proper assistance
We have changed the Service account password for Iny90 -800xa system with PLC Connect.
