Note:
Due to the fact that communication speed is increased when you use the read CHR
command to read characters, it is recommended that you use this command.

Read memory command
Example:
Address: Read the double-word data “75,000” (DEC) contained in the address 0020
(0014H).
- Host side
There should be no more than 5 DLEs.
Address:
Top address of the data memory to be read (HEX ASCII)
Count:
Number of characters to be read (HEX ASCII)
* When the data to be read is not continuous, “DLE” is inserted as a delimiter
between the breaks.
- V series side
Address:
Top address of the data memory to be read (HEX ASCII)
Count:
Amount of data memory to be read (HEX ASCII)
The read sequence is the same as the command sequence (HEX ASCII).
