■Description, data type of result
Processing details
• If the data specified with (S) is true, the bit data specified with (D) is reset.
• (S) can be omitted. At this time, the format is "RST(D)" and device reset is made unconditionally.
• When this instruction is set as a transition condition in the last block of a transition program, whether the data specified with
(S) is true or false is returned as logical type data. In this case, (S) cannot be omitted.
Operation error
An operation error will occur if:
• (D) or (S) is an indirectly specified device and its device No. is outside the range.
Program example
■Program which resets M100 when either of M0 and X0 is 1
■Program which resets M100 when #0 is equal to D0
■Program which resets Y0 unconditionally
