Read directly through PME software or network

Chapter 5: Easy Configuration and Troubleshooting

5.1 PAC Machine Edition (PME) Integration

The PAC8000 uses the same engineering software as the PACSystems controller - PAC Machine Edition (PME). This enables users to:

Unified hardware configuration: Configuring controllers, networks, and I/O in one project

Consistent user experience: use the same editor regardless of project size

Simplify HMI development: Share tag database with QuickPanel+HMI to reduce repetitive work

5.2 PROFINET GSDML file support

For PROFINET networks, PAC8000 provides standard GSDML files. Users only need to import files to easily configure the network of I/O devices without the need for complex programming.

Chapter 6: HART Support and Asset Management

6.1 Integrated AMS

The PAC8000 Modbus EBIM is capable of directly transmitting HART data to Emerson's Asset Management System (AMS). This means:

Remote configuration: HART instrument parameters can be set in the control room

Diagnostic access: Real time acquisition of instrument status information (such as sensor faults, electrode contamination, etc.)

Predictive maintenance: Identifying potential issues in advance through status monitoring

6.2 HART Data in Process Control

In addition to asset management, PAC8000 can also use HART data in process control applications. For example:

Regularly poll the status of HART devices

Trigger alarm when state changes

Use secondary variables such as temperature and pressure for control logic

These features help shorten debugging time, reduce maintenance costs, and improve factory availability.
