3. The module converts analog signals into binary or BCD format,
and stores theses values until the processor requests their
transfer.
4. When instructed by your ladder program, the processor performs
a read block transfer of the values and stores them in a data table.
5. The processor and module determine that the transfer was made
without error, and that input values are within specified range.
6. Your ladder program can use and/or move the data (if valid)
before it is written over by the transfer of new data in a
subsequent transfer.
7. Your ladder program should allow write block transfers to the
module only when enabled by the operator at power–up.
The accuracy of the input module is described in Appendix A.
Your input module package contains the following items. Please
check that each part is included and correct before proceeding.
