Operand Data AreasLadder Symbol
When the execution condition is OFF, TCMP(023) is not executed. When the ex-
ecution condition is ON, TCMP(023) compares S to the content of TB, TB+1,
TB+2, ..., and TB+15. If S is equal to the content of any of these words, the corre-
sponding bit in R is turned ON, i.e., if S equals the content of TB, bit 00 is turned
ON, if it equals the content of TB+1, bit 01 is turned ON, etc. The rest of the bits in
R will be turned OFF.
TB cannot be one of the last 15 words in a data area because it designates the
first of 16 words.
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
EQ (A50006): Content of R is zero after execution.
The following example shows the comparisons made and the results provided
for TCMP(023). Here, the comparison is made during each scan when CIO
000000 is ON.
