Connecting A Got In A Bus Topology; Data Exchange Between Two C Controller Modules - Mitsubishi Electric Q12DCCPU-V User Manual

1
OVERVIEW
(18)The device function allows an access similar to that of a programmable
controller CPU.
A device such as a programmable controller CPU can be created in the work RAM of
the C Controller module.
Access methods from peripheral devices (GOT or MX Component and others) are the
same as those for the programmable controller CPU. Therefore, connectivity is
improved.
Device functions cannot be used for the following C Controller modules.
(a) Communication with a GOT without using any program (connecting a GOT in a
(b) Data exchange between two C Controller modules

ret = mdReceive (Path, stno, devtyp, devno, size, data);
2)
/*Write data to devices of C Controller module (CPU No.1). */
ret = mdSend (Path, stno, devtyp, devno, size, data);
1) Reads devices of C Controller module (CPU No.1) to C Controller
module (CPU No.2).
2) Writes data to devices of C Controller module (CPU No.1) from
C Controller module (CPU No.2).
