14.2.2 Explicit messages
“ Explicit Messages” can transfer parameter data between controllers and the SLC-CPU via the
DeviceNet parameter channel.
Data between the “ SLC5/04-CPU” , DeviceNet scanner “ 1747” and the DeviceNet device is
transferred via “ module files” :
Module file DeviceNet data direction Data path
•
M0 Output data from the CPU to the DeviceNet node via a scanner
•
M1 Input data from the DeviceNet node to the CPU via a scanner
The CPU writes or reads module file data by means of copy commands from the scanner. The data
are organized by the CPU memory of the processary. Further data processing then uses the data
from the processor memory.
