Change Detect DC Input Module (CD332)
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.
