Job title: controls engineer location: warran, mi duration: long term job description : ~ the error proofing platform (epp) is a sophisticated system designed to prevent manufacturing defects and ensure high-quality production through automation and real-time monitoring.
~&##*; ? What is gm's error proofing platform (epp)?
~ epp is gm's standardized system for error detection and prevention across its assembly lines.
~ it evolved from earlier systems like gep and sep (scalable error proofing), and is now integrated into gm's global common controls software (gccs-2) framework.
~ epp combines hardware, software, and configuration tools to monitor and control production tasks at the track zone and footprint levels.
key components: sep/epp server : runs sql server, rockwell rslinx, and ge fanuc cimplicity hmi software.
cell controllers : allen-bradley logix * plcs manage local automation tasks.
operator interfaces (ois) : include light stacks, i/o modules, and bypass/release keys for manual overrides.
runtime ui : allows engineers to monitor, simulate, and validate production tasks in real time.
how it works: engineers configure tasks using templates and logic flows.
the system uses triggers (single or complex) to initiate error checks.
it supports main, backup, and alternate tools to ensure redundancy.
ethernet i/o mapping and io-link architecture connect sensors and devices for real-time feedback.
