Valid Devices
For the valid device address range, see pages 6-1 and 6-2
(Basic Vol.).
Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
Valid values for Bits to designate the quantity of bits searched are 1 through 256. Make sure that the search area designated by S1 plus Bits is within
the valid value range. If the source data is out of the valid range, a user program execution error will result, turning on special internal relay M8004
and the ERR LED on the CPU module.
When a user program execution error occurs, the execution of the instruction is canceled. The value of D1 is left unchanged and the next instruction
is executed. For user program execution errors, see Chapter 4 “User Program Execution Errors” on page 4-21.
Since the ENCO instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used as required.
Examples: ENCO
When input is on, a bit which is on is sought. The search begins at S1 until the first point which is
set (on) is located. The quantity of points from S1 to the first set point (offset) is stored to the
destination designated by device D1.
If no point is on in the searched area, 65535 is stored to D1.

When input I0 is on, a bit which is on is sought in 64 bits starting at internal relay M4
designated by device S1.
Since internal relay M30 is the first point that is on, the offset from the first search point is 20,
and 20 is stored to data register D100 designated by device D1.

When input I1 is on, a bit which is on is sought in 64 bits starting at bit 0 of data register D10
designated by device S1.
Since bit 8 of data register D11 is the first point that is on, the offset from the first search point
is 24, and 24 is stored to data register D100 designated by device D1.
