Unprotected Read Block
Use this command to read a block of data from any area of data table
memory in a programmable controller. Use the address (L ADDR) field
to specify the starting logical byte address for where to read. Use the
SIZE field to specify the number of bytes to be read. To specify a number
of words, the L ADDR and SIZE fields should have even values because
controller words are two bytes long.
