The workstation is capable of the following functions as a minimum: PDW Functionalities

Logging                                                                                                                              GE Proficy iFIX

The system verifies the operation of the communication channels on a regular basis and alarms on any failure. The system has communication error checking schemes and alarms on repeated failures. The system will periodically test and validate the integrity of the backup communication ports and alarm on any failure.

Time synchronization

The engineering workstations and MicroNet systems synchronize time every 5 minutes, using the Simple Network Time Protocol (SNTP). Within this time the MicroNet System will ensure time accuracy within applicable specifications. MAC shall provide SNTP servers connected to the CCS systems. The accessibility of the SNTP servers shall be provided by MAC.


A log is available for tracking operation and engineering actions or changes. Actions are divided into “Operation” and “Engineering”. Operation actions include normal operator actions that are logged in history files including:
• Change made to the mode of a controller
• Change made to the setpoint of a controller
• Alarms, including system diagnostic alarms.
• Shutdowns
• Turbine/Compressor critical running parameters, e.g. Min Gov Reached, Surge Control Line related events, Rate controller activated, etc.
Engineer Actions consist of normal engineer actions that are logged in history files, including:
• Download or modification of tag or module configuration
• Forcing member of a redundant pair on or off primary, status and placing devices on-line or off-line.
The system logs all local and remote access to the system.
Maximum number of Alarms and Events Queue display is 30 000. Events in the PDW are as alarms but with different status and area. Maximum Alarm and Event history is depending on the amount of disk space available on the PDW.



Data required for a complete backup and restore can be archived to removable media or to a network server. The control system is configured to automatically backup a control database, system configuration and other vital information to the hard-drive once a week. This can be done manually by giving a command as well. The system is configured to maintain a minimum of two sets of a complete backup and recovery data for each workstation, server and/or controller connected to the PCS on off-line storage media.

All PCS configuration parameters, including tag data, workstation configurations and controller module configurations are stored on redundant on-line media. On-line historical data is stored for access via history trends, displayed listings, and printed listings.
The workstation is capable to generate a hardcopy/softcopy of any active display available. The workstation has the capability of backing up the CPU memory onto its internal hard drive and on a removable storage media.
In NMR 602.11 “Configuration and Graphics Guideline” more details can be found regarding backup.

Additional Software
