Q6
A communication error occurred between the client and server. Will
data collection continue?
A6
Because data collection is performed between the server and data collection devices, the
operation continues even when a communication error occurs between the client PC and
server PC.
When a communication error occurs between the client PC and server PC, the client logs
out from the server. The project that was open is closed. In this situation, if data collection
was in progress and the project’s Keep Lock State was set to ON, the project will remain
locked.
To control the project before the communication recovers, perform either of the procedures
below from a client on another PC using the same project.
• Open the project using the same user.
• Log in as an administrator. On the
Project menu, click Unlock Project Forcibly to unlock
the project.
Q7
Unable to control the project. Why?
A7
Below are possible reasons.
• The user is not assigned privileges to control the project. → Open the project using a user
who has privileges to control the project, such as Owner, Manager, or Operator.
• The project is locked. → If an owner, manager, or operator user is logged in, the project
is locked. Other users can only monitor the project. Wait until the other user using the
project closes it.
• The project is locked. → If data collection is in progress and the project’s Keep Lock
State is set to ON, the project remains locked even when an owner, manager, or operator
closes the project. To control the project, perform either of the following procedures.
• Ask the user who locked the project to unlock the project.
• Clear the Keep Lock state.
Q8
I forgot the user password. What do I do?
A8
If the administrator password is lost, there is no recovery method. Contact your nearest
YOKOGAWA dealer.
If a user password is lost, the administrator can initialize the password. Then, the user can
log in with the initialized password (blank) and set a new password.
