• Reads the data of the specified number of bit memory tables, starting from the
specified bit memory table.
• A maximum of 100 tables can be read at one time.
• If number of table entries which is not multiple of 16 is specified, 0 is inserted in
remaining bit (left most bit).
• The number (n) of 4 hexadecimal digits value to be read out is as follows:
n=(number of bit memory tables to be read–1)O16)1
(O indicates the subtraction of the integer.)

The contents of bit memory table are represented as 1 bit data
(OFF=0, ON=1) and 16 entries of bit memory table are read out
as 4 hexadecimal digits value. (Table entries with smaller num-
ber is the rightmost bit.)
The bit memory table data is delimited by commas by each 16
tables.
Check sum (2 hexadecimal digits)
This is always added.
