Sequence of operations for starting up the serial I/O board SCB1:

With the power supply disconnected, insert the SCB1 board into slot 2 (or, if you have installed a
1
technology board, into slot 3).
Set bus address on SCI using DIP-Fix switch S1 (each SCI slave requires its own address number):
2
Address number
Switch setting S1
Mount the interface board(s) on the rail, make the connection to the 24 V power supply and the fiber optic
3
connection between SCB1 and SCI.
Depending on the type of SCI slaves used and the functions required, the following parameters are
relevant with respect to board operation (for details, see the parameter list in Section 5 and operating
instructions for the boards):
- P660 Configuration of analog inputs of SCI1 slaves
The type of input signal for each input is parameterized via the indices.
- P661 Filter time constant of analog inputs of SCI1 slaves
Filtering of the input signal for each input is parameterized via the indices.
- P662 Offset compensation of analog inputs of SCI1 slaves
The input signal for each input is zero calibrated via the indices.
- P664 Actual value output via analog outputs of SCI1 slaves
A connector number is selected via the indices to define the output quantity at each output.
- P665 Gain of analog outputs of SCI1 slaves
The gain for each output is parameterized via the indices.
- P666 Offset compensation of analog outputs of SCI1 slaves
The output signal for each output is zero calibrated via the indices.
- P682 SCB protocol
Selection of operating mode of the SCB1 board (master for SCI slaves or peer-to-peer
communication via fiber optic cable).
- P684.2 SCB baud rate
Selection of transmission rate at which the peer-to-peer interface of the SCB1 should operate
(P682 = 3).
- P687.2 SCB telegram failure time
Selection of telegram failure time for the peer-to-peer protocol.
- P689.2 SCB peer forwarding
Identifies words in the received peer-to-peer telegram that should be forwarded immediately.
- P690i SCB actual values
Selection of parameter values that should be transmitted via the serial interface of the SCB
board.
- P090 or P091 for logging the board
- The display parameter r730 (diagnostic information) assists in the correction of problems during start-
up.
