One or more operands have been set incorrectly.
D and D+N+1 are not in the same data area.
Example In the following example, the content of IR 040 is set to #0000 and then incre-
mented by 1 each cycle. For the first two cycles, AVG(––) moves the content
of IR 040 to DM 1002 and DM 1003. On the third and later cycles AVG(––)
calculates the average value of the contents of DM 1002 to DM 1004 and
writes that average value to DM 1000.
5-23-4 SUM – SUM(––)
Limitations The 3 rightmost digits of C must be BCD between 001 and 999.
DM 6143 to DM 6655 cannot be used for D.
If bit 14 of C is OFF (setting for BCD data), all data within the range R
1
to
R

+N–1 must be BCD.
