Conversion instructions

Encodes the contents of data specified by s according to the contents of n if the trigger EN is in the

ON-state. The encoded result is stored in the 16-bit area specified by d starting with the specified

bit position. Invalid bits in the area specified for the encoded result are set to 0.

b specifies the starting bit position of destination data d and the number of bits to be encoded using

hexadecimal data:

Bit No. 0 to 3

Bit No. 8 to 11

(The bits No. 4 through No. 7 and No. 12 through No. 15 are invalid.)

 Put at least one bit into the area to be checked to avoid an error message

from the PLC.

 When several bits are set, the uppermost bit is evaluated.

This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which

is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the

"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears

under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming

area to open the list of recently used elements.

The variables s, n and d have to be of the same data type.
