How Do I Create A Program To Input 2-Digit BCD Data From A Digital Switch To CIO 0.08 To CIO 0.15 And Then Move The Data To Specified DM Area Words?
Assuming that CIO 0.00 to CIO 0.07 are allocated to other input bits, the following two conditions must be met to create the program.
1.Only the digital switch value from CIO 0.08 to CIO 0.15 is to be extracted from CIO 0.
2.The 8 bits extracted in the previous step must be moved to the lower 8 bits of a word so that they can be used in processing in the next program rung.
What Is a Digit?
A "digit" is a single numeral. In this case, the instruction name MOVE DIGITS comes from the meaning to send a BCD value in digit (4-bit) increments.
