The Do-more CPU module assigns the following memory addresses to this module.
NOTE 1: The data format of the WX addresses is ‘Signed Word’. They store -32768 to 32767 as default.
To read and write 0 to 65535 into these memory addresses, use the casting ‘:U’ (‘:U’ is the casting for
‘Unsigned’ format). For instance, if you selected the voltage input for the first analog input channel and
WX0 is assigned to the channel, use ‘WX0:U’ to access this memory address in the ladder program and
other tools in Do-more Designer.
