The following table shows the functions and ranges of the parameter words:
Parameter Function
P1 BCD point #1 (A
P1+1 Hex. point #1 (A
P1+2 BCD point #2 (B
P1+3 Hex. point #2 (B
The following diagram shows the source word, S, converted to D according to
the line defined by points (A

The results can be calculated by first converting all values to BCD and then using
the following formula.
Results = B – [(B
Y
ER: The value in P1+1 equals that in P1+3.
Indirectly addressed DM word is non-existent. (Content of DM word is
not BCD, or the DM area boundary has been exceeded.)
P1 and P1+3 are not in the same data area, or other setting error.
EQ: ON when the result, R, is 0000.
When 00000 is turned ON in the following example, the BCD source data in DM
0100 (#0100) is converted to hexadecimal according to the parameters in DM
0150 to DM 0153. The result (#0512) is then written to DM 0200.
