Selection Notes

One industrial Ethernet interface and no RS-485 or RS-232 port means this panel talks to the controller over PROFINET only -- a KTP900 Basic variant with a serial port is the pick when the target PLC doesn't support PROFINET. The 10 MB user memory and 800x480 resolution fit machine-level status, alarm, and recipe screens (50 recipes, 100 records each); a heavier multi-screen application needs a Comfort Panel instead of the Basic line. Marine approvals across GL, ABS, BV, DNV, LRS, and NK make this panel usable in shipboard control panels without sourcing a separate marine-rated model.

Applications

Machine-level operator interface for status and alarm display and recipe entry, PROFINET-connected HMI on SIMATIC S7-1200/S7-1500 stations, and marine or offshore control panels.
