4 -5. Layout of scanner I/O

I/O mapping image at the Gateway (GW ) Unit communication port is shown in examples 1 and 2.

In this product, regardless of the quantity of the I/O equipment, continuous 4 Groups are automatically occupied. ( 1/2 RACK occupation ).

Each communication port occupies all of 16 points in corresponding Group.
