By enabling the SSI function the module starts with sending the clock
signal and with evaluating the encoder values. In the operating mode
"listening mode" the module starts with evaluating the encoder
values.
Range of values:
0 = disabled
1 = enabled
The module is a SSI interface module for direct connection to a SSI
encoder. With a parameterization the module may be adapted to the
corresponding SSI encoder. Here interrupts may be activated, which
are released when reaching a comparison value respectively limit.
The module has the following operating modes:
In the "master mode" the module is directly connected to a SSI
encoder. Here the SSI encoder is power supplied by the SSI inter-
face. To get data from the module serves for a clock signal for the
encoder and stores the received data stream in the process image.
In the "listening mode" the module, which is listening is passive con-
nected between SSI encoder and master module. For this operating
mode the SSI encoder is to be power supplied by the master module.
During operation the module listens to the signals of the SSI telegram
and stores the received data stream in the process image. Even here
the module is to be adapted to the corresponding counter by parame-
terization. The parameter transfer rate is not relevant.
