118 Appendix Actron AB15. Appendix Address typesThe following address types are used in the H series PLC:15.1. Physical I/OXWXDXYWYDYDigital input. May also be bit in analog input (WX).Word Input (16 bits) . Usually analog.Double Word Input (32 bits)Digital output. May also be bit in analog output (WY).Word Output (16 bits). Usually analog.Double Word Output (32 bits)15.2. Internal I/O15.2.1. M type memoryM type share bits and words. Every word (double word) consists of 16 (32) bits whichcan be individually accessed.MWMDMBit Internal Output. Is also bit in internal word (WM, DM).Word Internal Output (16 bits)Double word Internal Output (32 bits)15.2.2. R type memoryR type memory do NOT share bits and words. The word area is increased with largermemory modules (RAM).RWRDRBit Internal Output. Is NOT bit in internal word (WR, DR).Word Internal Output (16 bits)Double word Internal Output (32 bits)15.2.3. L type memoryLink type memory may be shared between PLC's via the LINK-H module. Bits andwords. are shared. Every word consists of 16 or 32 bits which can be individuallyaccessed.LWLCPU Link Area. Bit to be shared between linked PLC's. Is also bit in link word(WL, DL).CPU Link Area word (16 bits)Copyright Actron AB, 1992
