Available Internal Data
See
Appendix A - I/O Signal Descriptions
on page 22
for additional details regarding each input/output.
Unless stated otherwise:
•
In each instance, bytes are stored in little endian
order (most significant to least significant).
•
PROFIBUS and PROFINET data must be mirrored
by the PLC to get the correct data out on the PLC
side. When the data is mirrored, the least significant
byte is inserted into the most significant spot, and
the most significant byte is inserted into the least
significant spot.
Example
:
•
Values sent through the CGM are subject to the
same maximum and minimum restrictions as those
experienced through the ADM. For example, flow
rates cannot be set to a value less than zero.
NOTE:
Automation Outputs can be monitored by the
corresponding Automation Inputs to verify the EFR
received the data correctly.
