Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with DL BCM Server. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
HMI Setting
| Parameters | Recommended | Options |
|---|---|---|
| PLC type | DL-BCM Server | |
| PLC I/F | RS232 | RS232, RS485 |
| Baud rate | 9600 | 9600~115200 |
| Data bits | 8 | 8 |
| Parity | None | Even, Odd, None |
| Stop bits | 1 | 1 |
| PLC sta. no. | 0 | 0-31 |
Device Address
