Checking the I/O Unit Interface Status
Example:
The following allocations will be used for status when the default allocations
are used for C200HW PROFIBUS-DP Master Unit with one Communication
unit connected.
Output area
4 analog outputs
for Unit #3
Check the I/O Unit
interface status. If
normal, the status
will be as follows:
Input area
Unused
Unused
16 inputs for Unit #0
I/O Unit interface
status
8 analog inputs
for Unit # 2

•
The first two words of the input area is automatically allocated for the I/O
Unit interface status information. This allocation cannot be changed.
•
Words are allocated for the input/output data for each I/O Unit in the order
that the I/O Units are connected (I/O Unit interface addresses 0 to 3) in the
input area (input) and the output area (output).
