The existing automation technology was 20 years old and consisted of custom software that ran on a mainframe computer. Instead of alarms being reported to the field, they were sent to headquarters which then had to send an alarm notification to the field. Addition of new devices required custom drivers to be developed.
RealFlex was selected and installed to integrate several different types of field I/O devices through standard drivers and allow local alarm monitoring. Critical information is then sent back to the mainframe at headquarters through a custom interface. System has the ability to dial into headquarters for maintenance and support capabilities.
Alarms are immediately registered in the field, allowing for instantaneous action. This saves time and reduces the reporting burden on headquarters operations personnel.
In certain areas RealFlex may provide a local operator interface for locations not manned 24 hours a day.RFLink will be used to tie the outlying RealFlex systems, which will include Modicon and Allen Bradley PLCs, into the central control location. In other locations, an interface to the gas plant’s distributed control system may be implemented for transfer of critical alarm and flow information.
