The EtherNet/IP to Texas Instruments Remote I/O Master gateway allows an Allen-Bradley Programmable Automation Controller (PAC) to control TI 505 Remote I/O. This gateway allows a phased migration approach to be used when upgrading or replacing TI Remote Base Controllers. The gateway provides automatic creation of the TI Remote I/O scan-list and generates the associated RSLogix 5000 tags reducing engineering effort. Once the new PAC is commissioned the legacy I/O can be upgraded one module or one rack at a time as scheduled downtime is available. This gateway minimizes the risk of excessive downtime when upgrading legacy control systems.
