Operands:

S: Source device to be encoded D: Device for storing the result n: Number of consecutive

bits of S

Explanation:

1. The instruction encodes the lower “2

” bits of source S and stores the result in D.

2. They highest active bit in S has the priority for encoding operation.

3. This instruction is generally used in pulse execution mode (ENCOP).

4. When operand S is a bit device, n=1~8, when operand S is a word device, n=1~4

5. If no bits in S is active (1), M1067, M1068 = ON and D1067 records the error code 0E1A

(hex).

Program Example 1:

1. When S is used as a bit device, n = 1 ~ 8. Errors will occur if n = 0 or n > 8.

2. f n = 8, the decoded data is 2

= 256 bits data.

3. When X0 goes from OFF to ON, the data in (M0 to M7) will be encoded and stored in lower 3

bits of D0 (b2 to b0). The unused bits in D0 (b15 to b3) will be set to 0.

4. After the execution is completed, X0 is turned OFF and the data in D remains unchanged.
