System role

This section explains what the product does and where it acts in the surrounding system.

Function
Displays operator screens and exchanges touch, serial, and Ethernet control data in the GP4200 HMI system.
System position
Sits between the operator and the connected PLC or machine control network.
Upstream / inputs
Receives 24 V DC power, PLC data, and operator touch actions through the HMI interfaces.
Downstream / outputs
Presents HMI screens and sends operator input through serial or Ethernet communication.
Limitations
Unknown: installed project, PLC protocol settings, unit condition, and current commercial availability are not established by the product page.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • Pro-face identifies PFXGP4203TAD as a GP4200 3.5-inch analog touchscreen operator interface.

    Confidence: high

  • Pro-face records 320 x 240 TFT color display, 24 V DC power, isolated RS485, Ethernet, USB Type-A and Mini-B ports, IP65f and NEMA Type 4x/13 ratings, 16 MB flash, and 320 KB battery-backed SRAM.

    Confidence: high

Inferences

  • Inferred system position: Sits between the operator and the connected PLC or machine control network.

    Confidence: medium

    Rationale: The documented product function and interfaces establish the adjacent system stages.

Unknowns

  • Unknown: installed project, PLC protocol settings, unit condition, and current commercial availability are not established by the product page.

    Confidence: low

    Missing evidence: installed project, PLC protocol settings, unit condition, and current commercial availability are not established by the product page.
