6. Programming Information

Internally, the T1/T1S has an information called ‘I/O allocation table’ in its memory. This I/O allocation table shows the correspondence between I/O hardware and software, i.e. register/device.

The contents of the I/O allocation table are as follows.

Slot	I/O type
PU

0X+Y 4W

PU slot must be blank

Slot 0 is for basic unit (XW00, XW01, YW02 and YW03 are assigned internally)

Slots 1 to 3 are reserved for option cards

Slots 4 and 5 are reserved for Expansion unit

Slots 4 to 7 are reserved for T2 I/O modules

The T1/T1S operating system automatically sets the I/O type ‘X+Y 4W’ on the slot 0 position when the memory clear is executed for the T1/T1S.

When the T1/T1S program is developed in off-line, the above I/O allocation table should be set before programming. For this operation (called manual I/O allocation), refer to the programming tool manual.
