6. CONNECTION OF I/O UNITS TO
MACHINE INTERFACE

When the number of DI/DO points is insufficient with one I/O card, two
I/O cards can be used. The sink type and source type I/O cards can be used
in any combination.
The specifications are the same as for one I/O card.
Addresses viewed from the PMC are as follows:

Input (DI) addresses: X1000.0 to X1019.3
Output (DO) addresses: Y1000.0 to Y1014.7
Input (DI) addresses: X1020.0 to X1039.3
Output (DO) addresses: Y1020.0 to Y1034.7
The following figures show addresses assigned to each I/O card
depending on the number of I/O points.
Notes
1. The signals which the NC references directly are stored at
X1004, X1008, and X1009. When using the function for
referencing these signals, do not assign other interface
signals to these addresses.
2. A high–speed receiver (with a delay of 2 ms or less) is used
for manipulating data at X1004, X1013, X1024, and X1033.
