The SSI module should be used with channel 1 of the building block. The building block is to be
found at the address F080h. This corresponds to the peripheral address PY128. A device which
provides measured values is connected to the input channel of the SSI module. The building block’s
error messages should be filed in the flag byte MB 199 and the module’s error messages should be
filed in the flag byte MB35.
