Smart Touch Panels & META Smart I/O

Yes. That's exactly what META Smart I/O is for: sensors and signal taps digitalize even fully mechanical machines.

They're optimized for MSF MES but can display other web applications too.

Existing PLCs are read directly via native drivers or OPC-UA, with no reprogramming required.

A per-part event it can see electrically: a cycle or eject contact, a stroke signal, or a proximity sensor fitted for the purpose. For availability a state signal is enough, such as a lamp, motor or drive-enable circuit, but a lamp cannot count parts. Someone has to confirm what one pulse means, because a multi-cavity tool gives several parts per stroke and some machines pulse several times per part.

A qualified electrician, with the machine isolated: this is work inside a control cabinet. Safety-related circuits are never tapped, so nothing is taken off a light curtain, e-stop chain, two-hand control or safety relay; if the only per-part signal sits on one of those, a separate sensor is fitted instead. Signal voltage has to be established during the survey, because a 230 V lamp circuit and a 24 V PLC signal need different input handling.

It should not, because signals are read through an interposing relay or an isolated input, so the machine's own circuit is neither loaded nor altered. But a cabinet still gets opened, so on a machine under manufacturer warranty or a service contract, get written agreement first, before a breakdown starts the argument. Machine builders differ, and some treat any wiring in their cabinet as grounds to refuse a claim.

No. It counts cycles and reads machine states; it does not know what came out. Scrap has to come from the operator on the panel, from a quality check, from a downstream test rig with its own signal, or from a camera. A device on a machine gives you availability and output but no quality data, so plan that gap deliberately or gross output ends up being reported as good output.

It depends which one. If the network or server drops, the I/O device keeps recording locally and backfills when the link returns; hold time depends on event rate and buffer size, and timestamp accuracy depends on the device's clock between NTP syncs. If the machine loses power, nothing is buffered and the gap is filled by hand or not at all, which is why panels and I/O units worth trusting sit on a UPS. An operator on a dead panel records nothing.

Power at the panel and, preferably, a wired Ethernet drop for each one. Wi-Fi works, but a hall full of steel, welders and moving cranes is a poor place to depend on it, and a panel that drops its session mid-order loses operator trust quickly. Cable runs, mounting arms and cabinet space are usually the real schedule item. The hardware rarely is. Budget a short planned stop per machine and put it at a changeover.

Little day to day, but they are not fit-and-forget. Panel glass needs cleaning, added sensors drift or get knocked out of alignment during machine maintenance, and a signal tap can go silent after somebody rewires a cabinet. The practical control is watching for machines that stopped reporting before anyone complains, and keeping a spare panel and I/O unit on site so a failure is a quick swap.
