Project Description
Customer is an off-road capital equipment manufacturer with multiple paint lines with separate processors for conveyors, oven fans and wash/shot blast systems. Interconnected using DH485 for both messaging and common PanelView 1000 Touch Screen. Conveyor is an overhead power and free chain system by Norfolk-Webb.
Upgraded the SLC-5/03 processors to CompactLogix (1769-L33ER) with 1769 I-O. Moved touchscreen functions to Factory Talk PanelView 7 Enhanced.
Took another conveyor system that went thru load, shot blast, paint rooms, cure ovens and unload from a single 5/03 to three panels with separate Compact Logix processors, touchscreens and new VFD drives. Broken into 3 panels for line maintenance and repair reasons, customer had issues with taking down multiple functional areas for a problem requiring lockout/tagout in one specific area. Total of 6 new CompactLogix processors to replace 3 SLC5/03 processors and 1 SLC-5/04 processor.
New electrical schematics generated to show new I-O cards and revised e-stop circuit which moved to a 440C-CR30 programable safety relay with added Ethernet card for integration into the L33 ladder logic and alarming/display on Panelview7 Plus displays.
All conveyor motors moved to Rockwell PowerFlex 525 drives, linked to Compact Logix programing via Ethernet.
