Software 4.2.2 Summary of operands 45 Operands from to Name Max. qty. Bits Description I00.00 I01.15 Digital inputs 32 1 Max. I/O configuration depends on the model variant (à 3.1). The process image of inputs and outputs is stored in the on-chip RAM (à 3.10.5), therefore fast access O00.00 O01.15 Digital outputs 32 1 BI00.00 BO00.00 BI00.03 BO00.03 Byte inputs Byte outputs 4 4 8 8 For reading inputs directly by byte (wi- thout process image). For writing outputs directly by byte (wi- thout process image).
M00.00 M02.07 Fast bit markers 40 1 Bit markers in the on-chip RAM (à 3.10.5), therefore fast access SM00.00 FM00.00 LM00.00 SM15.15 FM15.15 LM15.15 Bit markers 256 256 256 1 1 1 Bit markers. Divided into groups of 256 for better differentiation.
