RM: Read Memory
This command is used to read data memory.
* Communication speed is increased when you use the read CHR command to read characters.
Details of read memory
Example:
Read the double-word data “75,000” (DEC) contained in the address $u0020 (0014H).
• Host side
DLE: When the data to be read is not continuous, “DLE” is inserted as a delimiter between the breaks.
There should be no more than 5 DLEs.
Address: Top address of the data memory to be read (HEX ASCII)
Count:
Number of words to be read (HEX ASCII)
• S8 series side
Address and count are omitted and DLE and data are transmitted. The read sequence is the same as the
command sequence (HEX ASCII).
