ABB CI858-1 Control Strategy Module

Got a customer in automotive manufacturing recently asking about this module. Turns out they needed a way to visualize complex PLC control logic without constant programming rework. That’s exactly what the CI858-1 does – turns spaghetti code into clear flowcharts engineers can actually work with. Makes troubleshooting 30% faster according to their maintenance team.

Used this in a chemical processing plant upgrade last quarter. The graphical interface made commissioning much smoother – operators could see valve interlocks in real-time. Works particularly well with ABB AC800M controllers. We’ve also seen it integrated with older S800 I/O systems through proper protocol converters.

Guizhou Yuanmiao Automation has 12 units in stock right now. All come with our standard 1-year warranty and pre-sale testing. For urgent replacements, WhatsApp me directly – we’ve done same-day dispatch before when needed.

Noticed some conflicting specs online – the 1.5kg weight includes installation hardware. The module itself is lighter. Also, while ABB lists 512MB memory, actual available space for strategy diagrams is around 420MB after system overhead. Would recommend checking your control logic complexity before ordering.
