Too Many
I/O Points,
Details
The 6 possible causes of the Too
Many I/O Points Error are listed
below. The 3-digit binary value in
A40713 to A40715 indicates the
cause of the error (values 0 to 5
correspond to causes 1 to 6,
below).
The 13-bit binary value in
A40700 to A40712 indicates the
details: the excessive value or
the duplicated unit number.
CPU Unit operation will stop and
the ERR/ALM indicator on the
front of the CPU Unit will light.
1) The number of I/O points will
be written here when the total
number of I/O points set in the
I/O Table (excluding Slave
Racks) exceed the maximum
allowed for the CPU Unit.
2) The number of interrupt inputs
will be written here when there
are more than 32 interrupt in-
puts.
3) The unit number of the Slave
Unit will be written here when
a unit number is duplicated or
the number of I/O points on a
C500 Slave Unit exceeds 320.
4) The unit number of the I/O
Terminal (excluding Slave
Racks) will be written here
when a unit number is dupli-
cated
5) The unit number of the Master
Unit will be written here when
a unit number is duplicated or
the unit number is outside of
the allowed setting range.
6) The number of Racks will be
written here when the number
of Expansion I/O Racks ex-
ceeds the maximum.

shows the meaning of the value
written to bits A40700 to A40712.
Values of 000 to 101 (0 to 5)
correspond to causes 1 through
