Block Transfer (Mini-PLC-2 and

PLC-2/20 Processors)

Appendix D

D2

Rungs 2 and 3: These output energize instructions (012/01 and 012/02) define

the number of words to be transferred. This is accomplished by setting a binary

bit pattern in the module’s output image table control byte. The binary bit

pattern used (bits 01 and 02 energized) is equivalent to 6 words or channels, and

is expressed as 110 in binary notation.

Rung Summary: Once the block transfer read operation is complete, the

processor automatically sets bit 07 in the input image table status byte and

stores the block length of the data transferred.
