Using the parameter "PC BCD-coded", you can inform the module whether target information,
tool offsets and zero offsets (in the modes "JOG ", "incremental approach" also speeds) sent by
the PC to the I P247 are in binary or BCD format.
Remember that each speed, each tool length offset and each zero offset of the corresponding
axis is interpreted in the selected format by the I P247 and this selected format will be used until a
different coding is specified in the machine data record.
