Input Assembly Instance 103
This assembly reserves a byte (8 bits) for every module on the system — regardless of
whether it has any inputs. The size of the assembly equals the number of modules present
plus five status bytes. This is the default assembly for the 198-DNGmodules when there are
more than six I/O modules. The following is the example data layout. The status and error
codes follow on pages A-15 and A-16.
