GE PAC8000 Proficy SafetgNet

Proficy SafetgNet is one of the main technologies currently offered by GE Intelligent Platforms and is an economical and efficient functional safety system capable of meeting today's safety requirements in emergency shutdown, fire gas and boiler management.

The PAC8000 SafetyNet system is a new addition to GE's Intelligent Platforms product family. Shared a base platform with the PAC8000 control system, developed and certified a new SafetyNet controller, a new Earth Leakage Fault Detection (EFLD) controller backplane, and two new SafetyNet I/O modules. The SafetyNet system uses the same terminal blocks, I/O module backplanes and power supplies as process control products. Its configuration and application design are carried out using safety application specific software tools - but share an identical programming environment.

The PAC8000 SafetyNet system uses the same basic structure as the PAC8000 conventional control system, in addition to incorporating the following specially developed components:

● SafetyNet Controller (8851-LC-MT)

● Special controller backplane for ground leakage fault detection (8751-CA-NS)

● SafetyNet I/O module - with HART analog input module (8810-HITX)

and discrete I/O modules (8811-IO-DC)

● Configuration WorkBench software WorkBench for SafetyNet systems


A key feature of the PAC8000 product is openness. SafetyNet nodes can communicate with standard PAC8000 nodes, data warehouse and asset management and HMI via redundant fault-tolerant Ethernet at speeds up to 100Mbit/s.

Standard I/O modules and SafetyNet I/O modules can be installed on SafetyNet nodes at the same time without affecting the functional safety of the nodes. Only standard applications can read data on standard modules, but both standard and SafetyNet applications can write data to standard modules. This flexibility can simplify hardware design.
