0017 Programming Techniques 9-171 This rung copies the Virtual DTHW word (B3:4) to the actual DTHW word (M0:1.3411) located in the 1747-BSN module. M-file accesses are interrupts to the processor and using virtual words minimizes M-file accesses and therefore minimizes the effects of these transfers on the ladder program scan time.
