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.
