Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with Crouzet M3 (LAD). Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
HMI Setting
| Parameters | Recommended | Options | Notes |
|---|---|---|---|
| PLC type | CROUZET M3 (LAD) | ||
| PLC I/F | RS232 | ||
| Baud rate | 115200 | ||
| Data bits | 7 | ||
| Parity | Even | ||
| Stop bits | 1 | ||
| PLC sta. no. | 1 |
*Support communications between HMI and PLC in pass-through mode
*Set LW-9903 to 2 to enhance the speed of download/upload PLC program in pass-through mode
When using pass-through, the driver will stop communication between HMI and PLC.
Device Address
| Bit/Word | Device type | Format | Range | Memo |
|---|---|---|---|---|
| B | I | DD | 1 ~ 99 | Input (default: 1 ~ 4) |

| W | Time | D | 1 ~ 6 | Time & Day * |
| W | Order | D | 1 | Command (write only) ** |
* address 1: second, address 2: minute, address 3: hour, address 4: day, address 5: month, address 6: year. The value range for “Year” is 0~99, entering “0” represents year 2000, entering “99” represents year 2099.
** run mode write 2, stop mode write 1.
Wiring Diagram
NOTE: The serial port pin assignments may vary between HMI models.
Diagram 1: RS-232 (CROUZET M3: 9P D-Sub)
| HMI | Direction | PLC |
|---|---|---|
| Pin assignments | RS232 9P D-Sub (Extension cable) | |
| Rx | ↔ (bidirectional) | 2 TX |
| Tx | ↔ (bidirectional) | 3 RX |
| GND | ↔ (bidirectional) | 5 GND |
| RTS | ↔ (bidirectional) | 4 DTR |
Suitable for HMI models with RTS communication pins.

| Tx | ↔ (bidirectional) | 3 RX |
| GND | ↔ (bidirectional) | 5 GND |
| TX+ (RS485) | ↔ (bidirectional) | 4 DTR |
Suitable for 4.3-inch HMI.
Diagram 3: RS-232 (CROUZET M3: 9P D-Sub)
| HMI | Direction | PLC |
|---|---|---|
