Example 2:
Remote I/O system in which the FP0 Control Unit has one FP0
I/O Link Unit. (I/O Link error flag is valid.)

The base word number that the Master Unit
at the left can control is 64.

[X3F is an I/O Link error flag]
The difference from example 1 is that the MSB (most
significant bit) of 2 words input (here X3F) is the I/O Link error
flag. This error flag indicates the communication condition
between this I/O Link Unit and the master unit.
The relationship of Inputs/Outputs between FP3/FP10SH and
FP0 in the above figure is shown below.

As this X3F is allocated as the I/O Link error flag in the FP0 I/O
map, Y67F and Y71F in the FP3/FP10SH I/O map are invalid.
