content of DBs. In other words, 1 and the content of DBs are added to DBs to

determine the destination word. The content of DBs is then incremented by 1.

1. DIST(80) will be executed every cycle unless the differentiated form

(@DIST(80)) is used or DIST(80) is used with DIFU(13) or DIFD(14).

2. Be sure to initialize the stack pointer before using DIST(80) as a stack op-

The following example shows how to use DIST(80) to create a stack between

DM 0001 and DM 0005. DM 0000 acts as the stack pointer.

First execution

Stack pointer

The offset or stack length in the control word is not BCD.

Indirectly addressed DM word is non-existent. (Content of *DM word

is not BCD, or the DM area boundary has been exceeded.)

During stack operation, the value of the stack pointer+1 exceeds the

length of the stack.

ON when the content of S is zero; otherwise OFF.

Ladder Symbols

C must be BCD.

DM 6144 to DM 6655 cannot be used for D.

COLL(81) can be used for data collection, an FIFO stack operation, or an

LIFO stack operation depending on the content of the control word, C.
