5.2.11 Reset Coil (R-COIL)
( 1 ) Operation
The R-COIL instruction sets the bit at the reset coil address to 1 (ON) when the bit input is 1 (ON). The set coil is
changed to OFF.

∗ C and # registers cannot be used.
( 3 ) Programming Example
In the following programming example, the reset coil is used to turn OFF the set coil that was turned ON in the first
line.
The DB000001 reset coil in the second line turns ON if the DB000002 relay turns ON while the DB000001 set coil is
ON, therefore turning OFF the DB000001 set coil.
The timing chart is shown below.
