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

When X0 switches from Off to On, the content of 2

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.

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

When X0 switches from Off to On, 2

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.

S
: Encoding source device.
n
: Length of encoding bit.
Encodes the data of lower "2
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.
