16.1
Out-of-group I/O Fetch
The access range to the controlled module is different from that to the non-controlled module. To fetch the data which cannot
be accessed, use the out-of-group I/O fetch function.
Accessing controlled module
The access range to the controlled module of the CPU module is the same as that to the single CPU system, and I/O refresh
for the controlled module and/or reading/writing to buffer memory of the intelligent function module are enabled.
Accessing non-controlled module
Access to the non-controlled module of the CPU module is limited to reading input (DX) and buffer memory of the intelligent
function module. Note that On/Off data of input (X)/output (Y) of the non-controlled module can be fetched using the out-of-
group I/O Fetch function. (
