The configuration switches for PSC-CAN and PSC-CP on ES150 series and ES030-10 are different. These switches are shown below.
Switch marked as 1 (closest to the flat cable) corresponds to A1, 2 to A2 and so on. The switches are only accessible if the unit's top cover is removed. The switches are located close to the CAN/Profi connection(s).
Observe the following when removing the (top) cover:
To set the baud rate, set A8 to on and A1-A7 according to table below. '1' means on, hence switch=down; '0' means off, hence switch up.
Baud rate (kbit/s) | Max bus length (m) | A1 | A2 | A3 | A4 | A5 | A6 | A7 | A8 |
1 Mbit/s | 25 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 |
800 | 50 | 1 | 0 | 0 | 0 | 0 | 0 | 0 | 1 |
500 | 100 | 0 | 1 | 0 | 0 | 0 | 0 | 0 | 1 |
250 | 250 | 1 | 1 | 0 | 0 | 0 | 0 | 0 | 1 |
125 | 500 | 0 | 0 | 1 | 0 | 0 | 0 | 0 | 1 |
100 | 700 | 1 | 0 | 1 | 0 | 0 | 0 | 0 | 1 |
50 | 1000 | 0 | 1 | 1 | 0 | 0 | 0 | 0 | 1 |
20 | 2500 | 1 | 1 | 1 | 0 | 0 | 0 | 0 | 1 |
10 | 5000 | 0 | 0 | 0 | 1 | 0 | 0 | 0 | 1 |
When A8 is set to off, the node number (address) can be configured. The node number can be anything from 1 to 127: a 7 bit binary number where A1 is the LSB1 and A7 is the MSB2. The following table gives some examples.
Node number | A1 | A2 | A3 | A4 | A5 | A6 | A7 | A8 |
2 | 0 | 1 | 0 | 0 | 0 | 0 | 0 | 0 |
8 | 0 | 0 | 0 | 1 | 0 | 0 | 0 | 0 |
56 | 0 | 0 | 0 | 1 | 1 | 1 | 0 | 0 |
127 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 0 |
1 LSB - Least significant bit (0d001)
2 MSB - Most significant bit (0d064)
No settings are required for the baud rate
The baud rate is pre-determined by the PROFIBUS-DP master and PSC-PB recognizes the required baud rate automatically and phases accordingly. The table below lists the supported baud rates. In case of branch lines of up to 1500kbps, the line length should not exceed 6.6m. The transfer rate for branch lines may not exceed 1500kbps.
Baud rate (kbit/s) | Max bus length (m) |
12 Mbit/s | 100 |
6 Mbit/s | 100 |
3 Mbit/s | 100 |
1500 | 200 |
500 | 400 |
187.5 | 1000 |
93.75 | 1200 |
45.45 | 1200 |
19.2 | 1200 |
9.6 | 1200 |
The address number can be anything from 1 to 127. Setting the slave address is similar to the PSC-CAN as above, where A8 has no function. The 7 bit address is set by A1 to A7 where A1=LSB1 and A7=MSB2.
1 LSB - Least significant bit (0d001)
2 MSB - Most significant bit (0d064)
