1. Auswahlrichtlinien & Häufige Fallstricke
2. Avoid oversized screens and picture resources in projects; Die 10 MB memory limit can be easily exceeded.
3. Resistive touch screen: compatible with gloved operation, avoid scratching with sharp hard objects.
4. IP65 rating applies only to the front panel. Ensure tight cabinet sealing; never spray water onto the rear side.
5. Program download methods: direct Ethernet connection or USB flash drive.
6. Script functions are unavailable; complex logic must be implemented inside the PLC.
7. Produktionsstatus: This model is mainstream 2nd-generation Basic HMI with no official end-of-life notice.

Vii. Typische Anwendungsszenarien

Vii. Selection Risk Checklist

1. Cannot connect DP-bus PLCs directly; PN-DP gateway is mandatory.
2. Basic panels do not support VBS scripts. Implement complex logic within PLC.
3. 10 MB internal memory; external USB required for extensive trend archiving.
4. Resistive touch screen supports gloved operation; avoid sharp hard objects.
5. Prefer PROFINET-certified industrial cables; standard office cables risk packet loss under continuous vibration.
