invalid). Before the communication with DTA series temperature controller, you have to set the content of
H'471A as H'0001 to allow the write-in of communication.

Explanation
When the equipment connected to IFD9502 is DTA series temperature controller, the length of
data downloaded from IFD9502 to DTA is preset as 2 words at addresses H'4701 and H'4719.
IFD9502 is able to download maximum 8 words. The length of data uploaded to IFD9502 from
DTA is preset as 2 words at addresses H'4700 and H'4719. IFD9502 is able to be uploaded
maximum 8 words.
Length of I/O data to be exchanged and address for mapping can be modified through changing
Class 0x99 as listed below. The modification will be valid after IFD9502 is re-powered. Maximum
16 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 0x99
