Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with Yamaha ERCD. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Interface: RS-232
HMI Setting
| Parameter | Recommended | Options | Notes |
|---|---|---|---|
| PLC type | YAMAHA ERCD | ||
| PLC I/F | RS232 | ||
| Baud rate | 9600 | 1200–19200 | |
| Data bits | 8 | 7 or 8 | |
| Parity | Odd | None/Even/Odd | |
| Stop bits | 1 | 1 or 2 | |
| PLC sta. no. | 0 | Station number does not need to be set. |
Device Address
| Bit/Word | Device Type | Format | Range | Memo |
|---|---|---|---|---|
| Bit | DI | DD | 0 ~ 15 | Sequence Input (Read only) |
| Bit | DO | D | 0 ~ 7 | Sequence Output (Read only) |
| Bit | EMG | D | 0 | Emergency stop status (Read only) |
| Bit | SRVO | D | 0 | Servo Status (Read/Write) |
| Bit | ORG_Sensor | D | 0 | Original sensor status (Read only) |
| Bit | RESET | D | 0 | Set on to reset program (Write only) |
| Bit | RUN | D | 0 | Set on to execute a program (Write only) |
| Bit | X_ADD | D | 0 | Set on to move robot to + side (Write only) |
| Bit | X_SUB | D | 0 | Set on to move robot to – side (Write only) |
| Word | P | DDD | 0 ~ 999 | PNT point data (Read/Write) *Note |
| Word | PRM | DD | 0 ~ 99 | Parameters (Read/Write) |
| Word | SWI | D | 0 | Switches program number to run RW0=program number (Write only) Set the parameter of RW register, and then enter any value in this register. |
| Word | MOVD | D | 0 | Directly moves to specified position RW1=X-axis position(mm), RW2=speed (Write only) Set the parameter of RW register, and then enter any value in this register. |
| Word | ORG | D | 0 | Return to original activity (Enter any value), Return to original status (Read/Write) |
| Word | MODE | D | 0 | Operation mode |
| Word | POS | D | 0 | Current position (Read only) *Note |
| Word | NO | D | 0 | Current program number (Read only) |
| Word | SNO | D | 0 | Current step number (Read only) |
| Word | TNO | D | 0 | Current task number (Read only) |
| Word | PNO | D | 0 | Current selected point number (Read only) |
NOTE: The value read in address types P and POS is multiplied by 100. In EBPro (EasyBuilder), set the object to display two decimal places (Right of decimal Pt.) to get the correct value.
