Selection Notes

The KTP400 Basic carries a single PROFINET interface and no RS 232, RS 422, or RS 485 ports, so it fits PROFINET-only machines rather than a serial-HMI retrofit. At 800 variables per device and a 256 kbyte recipe memory holding 50 recipes with 100 data records each, it covers a single machine station rather than a multi-line process panel that needs a larger tag count. The 4 hardware function keys plus touch operation give an operator two ways to acknowledge alarms or step through screens on machines run with gloves.

Applications

Fits compact, PROFINET-networked machine stations: conveyor sections, packaging cells, and pump or fan skids where an S7-1200 or S7-1500 CPU needs local operator control, alarm display, and recipe selection without a full SCADA client.
