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 PLC 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
PLC after it has been written. A program will not run properly if the index has
not been generated.
Bits 0 to 7 (second byte)
Bits 8 to 15 (first byte)
Data (command): The data to be written.
Changes the PLC to MONITOR or RUN mode, enabling the PLC to execute
