Description: Non Supported Hardware required upgrading from PLC5 hardware to Allen Bradley Control Logix.
The architecture of the original system was distributed across a local PLC 5 rack containing High speed counter card, analog and digital IO, DH+ Networks for HMI and PLC communications and RIO networks for 11 x field racks. HMI's connected to the system included 2 x PanelView Plus (Ethernet), 1 x PV 550 (DH+). Communications to other PLC's included SLC & Micrologix.
This system was upgraded over 2 weekend shutdowns to reduce impact to production.
The final system comprised of an Allen Bradley L71 processor, high speed counter card, and dual Ethernet cards, with local IO, Flex IO remote racks on Ethernet, and ControlNet with analog and digital IO. HMI's were reprogrammed to access the new L71 processor. The PLC code was translated to Logix 5000. Additional PanelView Plus 600's were installed to replace redundant local displays.
The project was successfully completed with no downtime attributed to the project works.
