What is the 1734-ADN(X) Adapter?
2-15
Cycling I/O Mapping
Cycling I/O Mapping is an EDS parameter accessible from the primary
DeviceNet that shows you how data is mapped in the adapter’s
scanlist. The data, as shown below, is listed in order of active modules
in the scanlist.
The data format is NN OBBB:b-BBB:b,IDBBB:b-BBB:b, where:
•
NN = node number
•
O or I = data type (output or input)
•
BBB = byte number
•
b = bit number
•
D = DeviceNet connection (C [COS/cyclic], S [strobe], or P [poll])
Automatic Device Replacement
With Automatic Device Replacement (ADR), the adapter automatically
configures a new replacement module.
IMPORTANT
If an I/O module’s data has multiple mappings, you
must use RSNetWorx for DeviceNet to browse to the
backplane to view the mappings.
IMPORTANT
The replacement module must match the original
module (i.e., same vendor I.D., device type, product
code, major, and minor revision) for ADR to work.
The parameters that must match are those selected in
the electronic keying portion of the scanlist. The user
determines the level of electronic keying.
The backplane configuration parameters (e.g., Auto
Address) should be set to “Do Nothing”.
