Section 4-4
An Analog Terminal uses 64, 48, 32, or 16 points. For this reason, in 8-point
mode, I/O allocations are as shown in the following table.
If a node number is outside the setting range, the words allocated to the Slave
will extend beyond the input or output area, which will prevent the Slave par-
ticipating in communications. If this happens, the COMM indicator will not
light.
Connector Terminals with 32 inputs or 32 outputs are allocated the words for
four 8-point nodes, i.e., they are allocated two I/O words. Therefore, the fol-
lowing nodes will be used in addition to the set nodes. Connector Terminals
with 16 inputs or 16 outputs will be allocated I/O as Slaves with 16 inputs or
Slaves with 16 outputs for the node number setting.
If a node number is not within the setting range, the words allocated to the
Slave will extend beyond the input or output area, which will prevent the Slave
from participating in communications. If this happens, the COMM indicator will
not light.
