Commands and Responses for C200HX/HG/HE and CQM1H-series PCs
Section 6-6
Response Block
Parameters
Program no. (command and response): Set to 0000 (Hex).
Beginning word (command and response): Set a relative byte address with
00000000 (Hex) as the starting address. The beginning word must be an even
number. The address set in the command will be returned in the response.
No. of bytes (command and response): The command specifies the num-
ber of bytes of data to write. This must be an even number of 07C6 (Hex) or
smaller (1990 or smaller in decimal). The number of bytes actually written will
be returned in the response. The leftmost bit (bit 15) is used to indicate the
completion of the command. It must be turned ON (1) when writing data to the
last address in the program area so that the PC can generate an index*. To
write only an index marker, specify 8000 (Hex) for the number of bytes.
*Generating an index is a process that enables a program to be used by the
PC after it has been written. A program will not run properly if the index has
not been generated.
Data (command): The data to be written.
6-6-8
RUN
