* Setting errors are indicated in IR n+2 (see section 5-3) and the ERR LED will
be flashing to indicate a non-fatal error.

* If the specified number of words would make the area exceed the boundaries of
the available buffer, DM, LR, IR or HR areas, the actual number of transferred
words will be limited as to remain within all of these boundaries. This setting
error is indicated in IR n+2 (see section 5-3) and the ERR LED will be flashing
to indicate a non-fatal error.
Notes • The Unit does not check the validity of the contents of any PLC data area,
from which output data is to be transferred. Any data present in the area
will be transferred to the output buffer of the Unit.
• If multiple fieldbus masters (e.g. PROFIBUS-DP, CompoBus/D, SYSMAC
BUS) are mounted on the same PLC system, only one of them can be
used in default mapping mode. The Unit does not check if the mapped
PLC input area is in use by other Units. If so, this Unit's data may
overwrite another Unit's data, or vice versa.
• If the settings cause two destination areas to overlap, the data of the
higher number area will overwrite the lower. This practice is to be avoided
by the user.
Meaning
Default mapping
C200HS:
Unit input buffer bytes 000 ~ 063 are mapped to
PLC addresses IR350 ~ IR381
C200HE,C200HG,C200HX:
Unit input buffer bytes 000 ~ 099 are mapped to
PLC addresses IR350 ~ IR399
One user-defined data input area
Two user-defined data input areas
Default mapping (see value 0000)
