DECO


The DECO instruction decodes the absolute value of n bits saved in the data register S and turns the corresponding bits ON starting from the data register D. All other bits in the data register D are turned OFF.

Ladder Diagram Example


When the contact, M0.0 is ON (1), the instruction decodes 27 bits of the data register, D0, and stores the result in D2.

DECOP


The DECOP one-shot instruction decodes the absolute value of n bits saved in the data register S and turns the corresponding bits ON starting from the data register D. All other bits in the data register D are turned OFF.
Every time this instruction executes, it energizes the output only once.

Ladder Diagram Example


When the contact, M0.1 is ON (1), the instruction decodes 25 bits of the data register, D10, and stores the result in D12.
