In the multiple Receive (RXD) Commands
processing, the number of the same-time stored
devices which is sum of the number of the stored
device of Device and the number of the index
device of Registering Constant (Character) or
Registering Constant (Hexadecimal) , is over
800 words.
Change settings so that the total
number of devices used for storage
at one time does not exceed 800
