Configuration

PSC-CAN

As described in the CAN interface description page the baud rate and the node address can be set by using the eight DIP switches (A1-A8) at the rear of the power supply. Switch A8 has a special function: it determines if the baud rate or the node number is to be set. Switches A1 to A7 determine the value of baud rate or node number. During power up, the PSC-CAN reads the value of the DIP switches and sets its CAN-bus configuration accordinly.

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).

Safety Instruction

Removal of cover

Observe the following when removing the (top) cover:

Baud rate

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

Node number

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)

PSC-PB

Baud rate

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

Slave address

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)
