Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with CoDeSys V3 Ethernet. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.

HMI Setting
| Parameters | Recommended | Options | Notes |
|---|---|---|---|
| PLC type | CODESYS V3 (Ethernet) | ||
| PLC I/F | Ethernet | ||
| Port no. | 1740 | *Note | |
| Source port no. | 1742 | *Note | |
| Protocol | V3 UDP/IP | V3 UDP/IP V3 TCP/IP V3 TCP/IP Communication Optimum V3 UDP/IP Communication Optimum | |
| Motorola Byteorder | |||
| User name, Password |
*Note: Codesys V3 UDP, UDP Communication Optimum — through the [Scan Network] function, you can get IP address and related Port no. information.
PLC Setting
Device user management: Enable or disable according to the settings.
If the response of the communication value is delayed, you can try to adjust the “Always update variables” setting parameter to “Enabled 2 (always in bus cycle task)”.
How to Import Tags
Set POU Under MainTask
Under u0022MainTasku0022 set POUPLC_PRG.
Add Symbol Configuration to Devices
Add u0022Symbol configurationu0022 into the Devices list.
Select PLC_PRG and Build Project
SelectPLC_PRGand its tag information is shown, then build the project: [Build] → [Generate Code].
Locate Generated XML File
A*.xmlfile is generated in the directory of the project.
Add Driver and Import Tags
In System Parameter Settings click [New] to add the CoDeSys V3 (Ethernet) driver into the device list, then click [Import Tags] and select the tag file (.xml) generated by the PLC software.
Confirm Import and Close
When the tags are imported successfully, click [OK] to leave.
NOTE: [Get Tag Info] The obtained address may be incomplete; it is recommended to use the [Import Tags] function.
