Introducing Logix SIS: Solution for Process Safety
The Challenges
“There are no highly available solutions to achieve safety in the latest hardware (5580)”
“I have to budget for implementation cost/time with the ControlLogix® SIL 2 w/ 1715 solution”
“I am unable to use additional features available with the newer I/O systems in ControlLogix® redundancy safety systems”
The Solution
- Adds safety into 5580 redundancy
- Achieve SIL 2 or SIL 3
- Leverages the latest controller and I/O solutions
- Expands upon existing safety implementation
- Supports the following:
- Concurrent safety execution
- Concurrent communications for standard and safety I/O
- Granular safety signatures
Configuration details
- Functionality unlocked with only a firmware update
- Available with V37.011 firmware
- Safety configurations are now handled completely by the controller
- Custom AOIs are no longer needed
- Concurrent safety execution in the primary and secondary controller
- Enables embedded safety diagnostics that are transparent to the end user
Features
- Enhanced containerization for safety edits
- Leverage granular safety signatures
- Utilized the latest 1756 hardware (5580) to build this solution
- There are no new specific catalog numbers required
- Take advantage of the latest I/O platforms (5094, 5015)
- Additional instructions supported
- Leverage instructions added to Ladder Logic Safety Editor
Avoid downtime during updates
- Upgrade to future versions for new features while running
- Leverage Redundancy System Update (RSU) to update all parts of the system:
- The controller
- The communication modules
- The redundancy modules
- NO downtime is needed to perform the RSU
- The secondary chassis will be unavailable during the update

Process Safety & Hybrid Safety
Targeted Applications
1.General Process Safety
Simplex IO is required for non-critical functions such as horns, lamps, and safety gates around machinery
Oil and Gas
2.Hybrid Safety
I/O availability is not the priority
Redundancy controllers provide the best flexibility
A mix of safety and standard control loops in the same controller
Reliability is very important; shutdowns are not OK
3.Tunnels/Transportation/Baggage Handling
Simplex I/O is required for non-critical systems
Redundant I/O will reside on critical systems such as fans
Simplex Safety I/O will be wired with relays in the event of I/O failure
4.Entertainment
Controller redundancy for availability
Simplex Safety I/O for fail-safe applications
5.Multi-zone control of robot lines that utilize machine safety
Each zone can be shut down independently
The controllers failing would shut down the entire line i.e. more important than I/O
6.Green Hydrogen
Emerging market with large growth potential
Layers of Protection
