Command Format
Response Format
Parameters Parameter area code (command and response)
Specify the parameter area to write. The parameter area code is designated
in two bytes. The leftmost byte is always 80 (hex) and the rightmost byte spec-
ifies the parameter area.
Beginning word (command and response)
Specify the first word to write. The beginning word address specifies the rela-
tive word address, with the beginning of the designated area as 0000 (hex).
Parameter Areas
The areas that can be written to are shown below, along with their parameter
area codes.
Number of words (command)
Bits 0 to 14 are used to specify the number of words to be written. (Each word
consists of two bytes.) Bit 15 must be ON (1) when data is written to the last
word in the specified parameter area or no data will be written. If the number
of write words is set to 0000, no words will be written and a normal end code
will be returned.
Data (command)
The data to be written. The leftmost bits (bits 15 to 8) of each word must be
specified first, followed by the rightmost bits (bits 7 to 0). The required number
of bytes in total for each write can be calculated as follows:
No. of words x 2 (each word consists of two bytes)
End code (response)
Refer to 5-1-3 End Codes for information on end codes.
