(3) Output to output modules and intelligent function modules
On/off data cannot be output to non-controlled modules.
Even if turning on or off the output of an output module or intelligent function module
controlled by another CPU is attempted from a C Controller module, no output is
made to the output module or intelligent function module.
(4) Access to the buffer memory of an intelligent function module
(a) Reading from the buffer memory
Buffer memory data of intelligent function modules controlled by other CPUs can
be read by using a bus interface function (QBF_FromBuf).
