The second block of 20 bytes will be made available in a similar manner, except this time the I/O

Input Instance will be selected as 2. Using a different I/O instance for these mappings will enable

the DeviceNet Scanner to access each block of data in a different manner (i.e. polled connection for

input instance 1 and COS connection for instance 2). The actual configuration of what connection

type to establish for each I/O instance is setup via the DeviceNet Scanner configuration (see Scanner

Configuration section below)

The second fieldbus mapping is illustrated above. The I/O Input Instance selected here is 2. Again,

we use a word transfer to link 10 I/O registers (20 bytes) to the fieldbus interface. The I/O Register

selection should correspond to the starting location of 10 I/O Registers in the Radio Interface – these

radio interface registers can be mapped to via appropriate radio I/O or block mappings (see WI-

GTWY-9 User Manual). The Fieldbus Interface I/O Location should be a unique word addressed

block of data within the 512 byte Fieldbus IN Area (Note that once the command type is chosen,

that the software will automatically select the next available fieldbus location to suit the mapping –

accepting this location is recommended).

The three filedbus mappings to suit the example are shown above. Standard I/O or Block Mappings

can be used to link the Radio Interface registers used by the fieldbus mappings with the radio

network (see the WI-GTWY-9 User Manual). The WI-GTWY-9-DE1 should be configured and

connected to the DeviceNet network in preparation for the DeviceNet Scanner configuration.
