Operand Specifications
Description TMHW(815)/TMHWX(817) creates an ON-delay countdown timer (10-ms
timer set in SV) between execution of the block program instruction preceding
it and the instructions following. TMHW(815) can time from 0 to 99.99 s with a
timer accuracy of 0 to 0.01 s. TMHWX(817) can time from 0 to 655.35 s with a
timer accuracy of 0 to 0.01 s.
