3.4 Automatic Allocation

3.4.1 Allocation without Using FPWIN GR7

 What is automatic allocation?
In cases where optional allocation or mount registration is not performed using FPWIN GR7,
the system automatically allocates starting word numbers and I/O numbers in order of
attachment of units.
 Allocation method
Numbers are automatically allocated in order of attachment of units when power supply is
turned on.
KEY POINTS

When automatic allocation is used, the system automatically reads the unit
attachment status, and formulates an I/O map, when power supply is turned
on.

If a difference with the actual attachment status is identified during
operation from the status when power supply was turned on, such a
difference is reported as a self-diagnosis error.

Based on the starting word number allocated to each unit, I/O numbers are
allocated.

In cases where optional allocation or mount registration has already been
performed, and the resulting information is registered in the CPU unit, the
system does not perform automatic allocation.

In cases where configuration data are to be set for input/output units and
intelligent units, optional allocation is required.
