Explanation
When the equipment connected to IFD9502 is custom equipment, the length of data
downloaded from IFD9502 to the equipment is preset as 2 words at addresses H’2101 and
H’2102. IFD9502 is able to download maximum 4 words. The length of data uploaded to
IFD9502 from the equipment is preset as 2 words at addresses H’2000 and H’2001.
IFD9502 is able to be uploaded maximum 4 words. The I/O mapping can be modified by
changing Class9F.
The length of I/O data to be exchanged and address for mapping can be modified through
changing Class9F as listed below. The modification will be valid after IFD9502 is
re-powered. Maximum 8 words are allowed for I/O data exchange.
If you are to return the I/O mapping to default setting, change Attribute1 of Instance1 of
Class 0x9F into H’0001 and re-power IFD9502. Please note that doing so can only recover
the current I/O data mapping in the custom equipment.

If IFD9502 fails to connect to DeviceNet by explicit messages due to the modification
on the I/O mapping between IFD9502 and the equipment connected to it (e.g. dlen_in,
dlen_out, data_in, data_out, etc), the I/O mapping between IFD9502 and the equipment
connected to it will not be able to return to default setting through explicit messages.
In the custom mode, DNAIFD9502 can still establish EXP/IO connection when there is no
equipment connected to it and the I/O mapping of IFD9502 can be returned to default
