Technical Specifications

Main Functions and Operating Principles

1. Industrial Process Visualization

The PFXGP6600TMD displays information collected from connected automation equipment. Operators can view machine status, production values, operating conditions, and alarm messages through graphical screens.

The screen layout can be configured to suit the application. For example, a production machine may use separate pages for operating status, manual control, alarm history, and maintenance information.

This centralized presentation helps operators understand machine conditions and respond to process changes.

2. Touchscreen Operator Interaction

The matrix-type touchscreen provides an interface for selecting screen objects, entering values, and navigating between operating pages.

Operators can use configured touch controls to issue commands, acknowledge alarms, change permitted settings, or access equipment information.

The two-point touch capability supports the specified matrix touch operation. Actual interaction functions depend on the application project and the configured screen objects.

3. PLC Communication

The HMI communicates with industrial controllers through its available serial and Ethernet interfaces. It can exchange information with supported PLCs and other automation devices using compatible communication drivers and protocols.

Typical exchanged data includes:

• Machine operating status.
• Motor and drive operating values.
• Production counters.
• Temperature and pressure readings.
• Alarm and fault information.
• Operator-entered settings.
• Process commands and control selections.

The actual communication method depends on the connected controller, interface configuration, cable arrangement, and software driver.

4. Alarm and Event Display

Alarm presentation is an important function in industrial operation. The HMI project can be configured to display abnormal conditions, equipment warnings, and process-related messages.

When an alarm occurs, operators can use the displayed information to identify the affected equipment and follow the appropriate response procedure.

Alarm history and event handling depend on the application configuration and available project functions.

5. Data Handling and Maintenance

The PFXGP6600TMD provides USB and SD card interfaces for supported data and maintenance operations.

Depending on the project and software configuration, these interfaces may be used for transferring application files, managing supported data, or performing maintenance tasks.

Role in Industrial Automation Systems

The PFXGP6600TMD is typically installed as the operator interface within a PLC-based automation architecture. It works with controllers, sensors, drives, and other field devices to present machine information in a form that operators can understand.

PLC and Controller Integration

A PLC executes control logic and processes input signals from connected devices. The HMI provides a graphical interface through which operators can monitor selected PLC data and enter authorized commands.

For example, an operator may use the touchscreen to select an operating mode or change a permitted setpoint. The PLC evaluates the command and controls the associated machinery according to its programmed logic.

The HMI does not replace the PLC’s control or safety functions. Critical interlocks and safety-related operations must remain implemented through appropriately designed control and safety systems.

Variable Frequency Drive Monitoring

In motor-control applications, the HMI can display drive-related information when the connected controller or drive communication arrangement supports it.

Typical displayed values may include motor speed, operating frequency, drive status, and fault messages. Operators can also be provided with permitted speed references or operating commands through the application.

Centralized Machine Operation

A single HMI project can organize information from different parts of a machine or production line. Screen navigation allows operators to move between equipment sections without needing separate displays for every device.

This is particularly useful in packaging machines, material-handling systems, and manufacturing equipment with multiple operating stations.
