Note 1 The ERC indicator on the Unit's front panel will light if an out-of-range setting is made in Set-
ting Parameter Group 1 (Continuously Refreshed Parameters), Setting Parameter Group 2
(Initial Settings Parameters), or the Expansion Setting Parameters.
The offset (the number of words) from the start address to the lowest memory address that
has the range error will be stored in the Address of Data Range Error.
If the lowest memory address that has the range error is an Expansion Setting Parameter, the
offset value shown in the Address of Data Range Error will be 100 or greater. (The value will
be 100 if the first word of the Expansion Setting Parameters is erroneous.)
For the correspondence between range error addresses and setting parameter or expansion
setting parameter addresses, refer to A-3 Correspondence Table of Analog I/O Unit Variables
and CJ-series CPU Addresses. "m" in the table indicates the first word allocated in DM. m =
D20000 + (N × 100) (N: Unit number)
2 When specifying Expansion Setting Parameters, be sure that the area does not overlap with
other areas that are in use.
If areas overlap, the memory may be overwritten and unexpected operation may occur.
