DeviceNet I/O Link Units
Section 7-7
Note
(1) The 32 bits each of I/O data are not always transmitted simultaneously.
In other words, 32 bits of data transmitted from the Master CPU Unit at
the same time will not always reach the CP1L CPU Unit simultaneously,
and 32 bits of data transmitted from the CP1L CPU Unit at the same time
will not always reach the Master CPU Unit simultaneously.
When the 32 bits of input data must be read together, modify the ladder
program in the CPU Unit receiving the data. For example, read the input
data twice in succession and accept the data only when the two values
match.
(2) Unused bits in the DeviceNet I/O Link Unit’s output words can be used as
work bits if they are not used for output from the slave.
(3) Unused bits in input words cannot be used as work bits.
Determining the Node
Number and Making DIP
Switch Settings
Setting Node Numbers
Use rotary switches SW2 and SW3 to set DeviceNet node number. The set-
ting range is from 00 to 63, and 64 to 99 cannot be set. Rotary switch settings
go into effect when the power is turned ON.
Note
The actual range of node numbers that can be set depends on the type of
PLC to which the Master Unit is mounted, and on the Master Unit setting. For
details, refer to the
DeviceNet DRT1-series Slaves Operation Manual
.
