4. I/O Allocation

4.1 I/O allocation and I/O register

The CD332 has the I/O type ‘i X 1W’ for I/O allocation. When the automatic I/O allocation is performed with mounting the CD332, the following I/O allocation table will be created in the T3.

(T-PDS screen example - in the case that CD332 is mounted on Slot 0 of Unit 0)

Then, one input register, XW(n) is assigned to the CD332.

In the above example, XW000 is assigned.

Note that the I/O type has ‘i’ designation. It means that the CD332 has interrupt generation function for the T3, also the T3 will not update the assigned input register in the batch I/O processing. To read data through the input register, the Direct I/O instruction (FUN235) is necessary.
