Naming the Inputs, Outputs and Markers

These data areas are organized byte by byte and consist respectively of 65536 bytes. You can access the data in these areas by bit, byte, word and double word.

Examples:

      I 5.2      // Bit no. 2 of input byte 5 (Bit-numbers from 0 - 7)

      QB 6       // Output byte 6

      MW 10      // Marker word 10, consists of MB10 (high,h) and MB 11 (low,l)

      ID 2       // Input double word 2 : IB 2(hh),IB3(hl),IB4(lh),IB5(ll)

In View|Options|PLC-Editor you can also adjust the IEC-Mnemonics, then inputs are not named with E but with I and outputs not with A but with Q.
