I need an Allen Bradley expert for connectivity and ladder logic support for SLC 500 PLC specifically SLC 5/04 processor and PanelView 1000. VFD issue as well. Troubleshoot code/program and discover changes needed on existing software. Able to sign NDA and work at site in Houston area. Job pays by the hour, based on experience and ability. If you have access to cables and adapters for PLC/HMI, is a plus.
