Error Code

Details

-4095

User login failed (Login)

This can be caused by an invalid user name or password.

The usual workaround is to check the user configuration and verify that the login exists and the password is correct.

-4094

No user logged in (Write)

This error occurs when a user tries to write a secured signal without being logged in. Signals can be configured to be secure so that you need to have a login that is allowed to write those specific signals.

The workaround here would be to login before writing the signal, or if it is the case, remove the write protection for the signal.

-4093

Insufficient user authorizations (Write)

This is similar to error -4094. This happens if the user is logged in but doesn’t have enough permissions to write the signal. This is normal if the user shouldn’t be able to do this operation. If he should, then the permissions should be updated so that he can write it, or the signal write protection should be removed.

-4092

User already logged on (Login)

-4091

Invalid user password (Login)

-4090

Max user count reached (Login)

-4089

Unspecified server error (Login, Write)

-4087
