Issue
Installing the Sigma IC-Gen on unsupported OS Platforms
Product Line
Satchwell Sigma
Environment
Sigma IC-Gen and Windows 7
Cause
Customers have the IC-Gen already installed on sites. The PC's/Server are now being upgraded and the supported OS are not generally available.
Resolution
Some basic testing using IC-Gen OPC software loaded onto a Windows 7 64 bit PC has been carried out. The software installs with no issues into the default locations.
The SigmaSvr can be run as a service as is it designed to do, but in this configuration no icon appears on the task bar, hence the status of the IC cannot been viewed at any time, although it is running and can be viewed as normal from the main Sigma server.
It is recommended that it is run as an application. This is done as described in Running Sigma server as an application There is a minor issue with closing the program. It can only be achieved using the task manager and performing an "End Task."
Testing has been carried out using the IC-Gen on the OPC platform. Only basic functionality was tested. An OPC simulator was used to generate values for the IO objects. Program objects where also used. Alarms and Logging were also setup and worked as expected.
The IC appeared to work correctly on the OS platform, but it has not been fully tested and is not supported in this configuration. Support in the event of a failure will be limited to basic operations. No capacity testing has been done so actual IO performance cannot be specified.
