Table 42 - N-File Descriptions (All N-files are 16-Bit integers)
N-File Description
N42 This N-file lets you read and write some values configuring the port.
N42:3 Time-out (read/write): Time (in seconds) allowed between messages to the N45 file. If the interface does not receive a
message in the specified time, it performs the fault action configured in its [Comm Flt Action] parameter. A valid
setting is 1...32767 seconds (5…20 seconds is recommended).
N42:7 Interface Port Number (read only): Drive port in which the interface resides.
N42:8 Peer interface (read only): Bit field of devices with peer messaging capabilities.
N45 This N-file lets you read and write control I/O messages. You can write control I/O messages only when the following
conditions are true:
The interface is not receiving /O from a controller. For example, there is no controller on the network, the controller is
in idle (program) mode, the controller is faulted, or the interface is not mapped to the controller.
The value of N42:3 is set to a nonzero value.
