Rockwell Automation 1769-ADN Compact I/O 1769-ADN DeviceNet Adapter - Manual (Page 149)

Publication 1769-UM001B-EN-P - October 2002
Application Examples 6-37
Target Device
Message Timeout
Message timeout is specified in seconds. If the target does not respond
within this time period, the message instruction will generate a
specific error (see MSG Instruction Error Codes on page 6-39). The
amount of time that is acceptable should be based on application
requirements and network capacity/loading.
Target Type
You can select either Module or Network Device. If you need to
message to a device on DeviceNet, select Network Device. If you
need to message to a DeviceNet parameter on the scanner, select
Module. This allows the control program access to module
parameters.
TIP
Note, many module parameters are not editable, and
some can only be edited when the module is in Idle
Mode.
