
S
: Encoding source device.
D
: Device that saves the encoding result.
n
: Length of encoding bit.
 Encodes the data of lower “2 n ” bit length from encoding source device S, and
saves the encoding result in D.

If multiple digits of encoding source device are 1, the command will process the
first digit starting from high digit.

This command usually uses pulse execution type command (ENCOP).

When S is the bit device, n = 1–8, when S is the word device, n = 1–4.
 When S is the bit device, the valid range of n is 0< n
≦
8. If n = 0 or n > 8, a fault
will occur.
 When n = 8, the maximum decoding will be 2 8 = 256 points.
 When X0 switches from Off to On, the content of 2 3 digit (M0–M7) is encoded and
saved in the lower 3 digits (b2–b0). The unused digits (b15–b3) in D0 become 0.
 When the command is executed, X0 turns to Off. The data in D is unchanged.

X0
 When S is word device, the valid range of n is 0< n
≦
4. If n = 0 or n > 4, the fault
occurs.
 When n = 4, the maximum decoding will be 2 4 = 16 points.
 When X0 switches from Off to On, 2 3 digit data of D10 (b0–b7) is encoded and
saved in the lower 3 digits (b2–b0) of D20. The unused digits (b15–b3) of D20
become 0. (b8–b15 in D10 are invalid data)
 When the command is executed, X0 turns to Off. The data in D is unchanged.
