GE Automation PAC8000 PLC

The GE Automation PAC8000 SafetyNet PLC is a Programmable Electronic Safety System, certified according to IEC 61508 as suitable for use in safety related applications up to Safety Integrity Level 2. The system is suitable for use in emergency shutdown, fire & gas and burner management applications. The SafetyNet System is programmed using the Workbench software package in common with the PAC8000 Process Control Products. In addition to providing the options of programming the required safety function in one of three IEC 61131-3 languages (Ladder Diagram, Function Block Diagram and Structured Text), the package also provides many useful tools to assist in testing and commissioning.

The 8851-LC-MT SafetyNet Controller stores and runs the SafetyNet application program which is downloaded from the Workbench. It manages a number of communication paths: with the IO Modules mounted on the local node via the internal Railbus; with other entities on the Ethernet LAN (other PAC8000 nodes, PCs running the Workbench programming tools, HMI, historian packages and asset management tools) and with remote mounted serial devices. The SafetyNet Controller also manages the implementation of the redundancy strategy either as master or standby.
