2-6 What is the H Series Fieldbus DeviceNet Adapter?
Cycling Node Status
Using the Cycling Node Status parameter, you can easily determine
the status of any H Series Fieldbus I/O modules with which the
adapter is experiencing problems. A corresponding text string
appears, including the MAC ID, and a description of the status code
reported in the Node Status Table. For more information on the Node
Status Table, see page 2-11.
For the connection sizes mentioned below, the I/O connection sizes
on DeviceNet are dependent on the scanlist confi guration on the
backplane.
Poll/COS Connection Consume Size
Poll/COS Connection Consume Size shows the size (number of data
bytes) consumed by the poll/COS (Instance 2) I/O connection on the
primary DeviceNet.
Poll Connection Produce Size
Poll Connection Produce Size shows the size (number of data bytes)
produced by the polled (Instance 2) I/O connection on the primary
DeviceNet.
COS/Cyclic Connection Produce Size
COS Produce Size shows the size (number of data bytes) produced
by the Change of State I/O connection on the primary DeviceNet.
Strobe Connection Produce Size
The Strobe Produce Size shows the size (number of data bytes)
produced by the Strobe I/O connection on the primary DeviceNet.
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])
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.
Automatic Device Replacement
With Automatic Device Replacement (ADR), the adapter
automatically confi gures a new replacement module.
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.
You determine the level of electronic keying.
The backplane confi guration parameters (e.g., Auto Address)
should be set to ‘Do Nothing’.
