Discrete Internals (%M)
Genius Global Data (%G)

Length Length of Map Descriptor
Ensure that the length does not exceed the table length
in the PLC. 1 - 1000
Address Starting address of read block / write block
The 1
st element of each Data type Table is referred to
as address one.
1 , 2 , 3
Positive whole numbers
Format Use to override the default format for obtaining data.
Bit tables are by default read by reading whole bytes
at a time (If the Length is 10 then 10 bytes of data are
read and placed in 10 data array locations)
If you wish to read bits instead then use this parameter
. (If the Length is 10 then 10 bits are read and each bit
is stored in its own location.) Bit, Byte
The format for %AI,%AQ and %R
cannot be changed.
