Functioning IP/IE5009
The SSI sensor interface module IP/IE5009 enables the direct connection of a SSI sensor to the fieldbus or the Coupler Box. The sensor is powered via the SSI interface. The module generates a pulse for reading the sensor and makes the incoming adapted data stream available to the controller in the process image. Various operating modes, transfer frequencies, bit widths and code implementations can be selected. The individual configuration is permanently stored in a register set.
The SSI interface is supplied with a data width of 24 bits and activated Graycode conversion. The baud rate to the SSI sensor is set to 250 kHz. The process data are output in the input data bytes D0 - D3. The mapping module is described in more detail in Chapter Mapping.
