How does Logic Matrix help you?
In R&D we use PCS 7 as our MET for research process control
Logic Matrix is critical for our complex interlock management
Benefits / Improvement
• Engineering
• More efficient programming of complex interlocks schema
• Less prone to errors / less testing required after a change
• Considerable time savings on current visualization
• Operations
• Better visualization of cause/effect for our technologist and scientist
Additional Comments: I estimate utilizing Logic Matrix will save between 15%
and 25% of project programming time over the life of a system.

How does Logic Matrix help you?
Safety Matrix is used extensively for safety interlocking functions since 2007
Benefits
• Visualization for Operations
• Cause/Effect understanding
• First out monitoring
• Sequence of Events
• Configuration efficiency for Engineering
• Cause/Effect strategy
• Commissioning & Checkout
• Considerable time savings on console design
Additional Comments: We estimate time savings of 15%-20% by utilizing Logic
Matrix for project programming – Avg. of 50 hours per standard system.
