Fig. 13.3−1 Data input /output of SSI interface
For the data input / data output, 4 bytes are available which are transmitted to the
module or output by the module.
)
Note!
Input and output data are lost when the supply voltage is
disconnected; they are not saved!
The input data can be used to control the outputs (I/O.0 and I/O.1) depending on
the encoder value.
Byte Assignment
0 Control Bits 0 ... 1
% Setpoint selection
00: No setpoint selection
01: Setpoint selection for output I/O.0
10: Setpoint selection for output I/O.1
11: Setpoint selection for outputs I/O.0 and I/O.1
Bit 2 Reserved
Bit 3 Condition for setting the output = HIGH
0: If SSI encoder value is higher than setpoint
1: If SSI encoder value is lower than setpoint
