Use the “Browse Controllers” dialog box to select the specific controller for the project. The Trusted

TM

OPC Server supports multiple controllers, which can be located by expanding the controller tree. Once
the controller for the project is selected, click the “OK” button.

Selecting “Cancel” from either the “OPC Server” selection dialog or the “Browse Controllers” dialog will
generate an error. A valid OPC controller must be defined in order to save the new project.

4.4.3. Times from OPC source are in UTC

Beneath the “OPC Controller” field is a check box entitled “Times from OPC source are in UTC”. OPC
servers generally supply date and time information using UTC (i.e. the GMT time zone). However,
some OPC clients are unable to convert from UTC to local time so the Trusted

TM

OPC Server can be

configured to present date and time values in either local or UTC. If the Trusted

TM

OPC server

selected for this project has been configured to supply date and times value pre-adjusted for local time,
then unselect this option to prevent the usual conversion from UTC to local time.
