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.
