UniOP ePAD03/04 Human Computer Interface

View the status and IP address of the Ethernet module on the system information page of the HMI.

Use the ping command to test connectivity.

Specify the correct IP address and timeout time in the transport settings of Designer.

Upgrade HMI firmware to the latest version.

Upgrade Path and Selection Suggestions

When ePAD03/ePAD04 cannot meet the requirements of a new project or needs to be migrated from this series to a higher performance platform, the following paths can be considered:

Path 1: Keep the ePAD platform and add extension modules

If the current project requires access to Profibus DP or Ethernet, simply purchase the corresponding optional module and insert it into the Aux port without replacing the HMI body. This is the lowest cost upgrade method.

Path 2: Upgrade to eTOP series

If you need color display, larger screens (5.7 inches or more), touch functionality, or faster processors, you can choose the UniOP eTOP series (such as eTOP 05, eTOP 10). These models also use Designer 6 software, and the engineering files can be partially reused, but the layout of the screen needs to be redesigned (due to significant differences in resolution).

Path 3: Completely replace with third-party low-cost text screens

When ePAD04 also exceeds the budget, a large number of domestically produced text displays on the market (such as Xinjie OP320 and Weikong LEVI series) can be used as alternatives. However, it should be noted that:

The communication driver of domestic screens usually only supports a few PLCs (such as Mitsubishi, Siemens, Delta), and may not be directly connected to non mainstream PLCs.

The programming software for domestic screens is completely different from Designer, and the project must be completely rebuilt.

The number and functions of physical keys are often fewer than the ePAD series (usually only 4-6 function keys).
