Communication settings
Slave address, baud rate and parity are dependent on the position of the S1 rotary switch and, if applicable, on objects 2028h, 202Ah, 202Dh.
| Configuration | Object | Value range | Factory settings |
|---|---|---|---|
| Slave address | 2028h | 1 to 247 | 5 |
| Baud rate | 202Ah | 7200 to 256000 | 19200 |
| Parity | 202Dh |
|
0x04 (Even) |
The number of data bits is always "8" here. The number of stop bits is dependent on
the parity setting:
- No parity: 2 stop bits
- "Even" or "Odd" parity: 1 stop bit
The following baud rates are supported:
- 7200
- 9600
- 14400
- 19200
- 38400
- 56000
- 57600
- 115200
- 128000
- 256000
You must save the changes by writing value "65766173h" in object 1010h:0Bh. The changes are not taken over until after the controller has been restarted.
Rotary switch
The PD6-E is equipped with a hex coding switch – similar to that shown in the following figure.
You can thereby determine the source for the slave address, the baud rate and the parity; the following table shows the possible combinations.
| Position of the rotary switch | Slave address | Baud rate and parity | |
|---|---|---|---|
| dec | hex | ||
| 0 | 0 | Object 2028h | Object 202Ah or 202Dh |
| 1-14 | 1-E | Number of the rotary switch | Object 202Ah or 202Dh |
| 15 | F | 5 | 19200, even Parity |
