When using an OMRON Master Unit, check the following points and perform the error
processing steps according to the indicator status.
• Register the scan list again.
First clear the scan list, check that all the Slaves have joined the network, and then cre-
ate the scan list.
• Check that the Slave's allocated I/O Area does not overlap with that of another Slave. If
there is an overlap, change the Slave's node address to eliminate the overlap.
• Check that the allocated I/O Area does not exceed the allowable range shown below. If
the I/O Area exceeds this range, change the Slave's node address to correct the prob-
lem.
When using another company's Master Unit, check that the I/O size registered in the Mas-
ter's scan list matches the actual I/O size of the Slave.
The I/O size is recorded in the following attributes of the Connection Object:
Interface 2 (Polled I/O Connection)
Produced Connection Size (input size)
Consumed Connection Size (output size)
OR:
Interface 3 (Bit-strobed I/O Connection)
Produced Connection Size (input size)
Refer to Appendix A DeviceNet Explicit Messages , and register the correct values in the
Master Unit's scan list. Refer to the DeviceNet master operation manual for details on reg-
istering values.
