Defining the Parameters of a Network Segment To start Network Configuration, open a project folder. On the File menu: A. Click on Open Project to open an existing project, or, B. Click on New Project to start a new project folder. Create a network segment. On the Edit menu: A. Click on New Segment, or, B. Click on Copy to copy a segment. Paste the segment, then change it as needed. If you copy a network segment, its exchange predefinitions are used for the pasted segment. However the exchanges for individual devices are not. The system illustrated below includes 4 network segments (repeaters are “transparent” to the system). Each network segment has its own configuration, which is included in the project folder for the system. So the system illustrated below would include four network configurations in its project folder.Number of TEST_P (test subscriber presence) instructions in the bus arbiter program. The bus arbiter can use TEST_P instructions to test for the presence of critical devices on the network. Using this instruction, it can detect more quickly when remote devices are lost. Since loss of devices is routinely detected during the normal scan, this instruction is most suitable for applications where the scan time is relatively slow.

Locked Network Segment

 A network segment can be locked to protect its configuration. You cannot connect a device to a locked network segment. Also, you cannot modify:
the network segment parameters
the definition of the master device for the locked remote I/O rack
the connection parameters for devices that are correspondents (including master devices) of the locked remote I/O rack
the transport time slots for the locked remote I/O rack
Exchanges for the locked remote I/O rack It is not possible to cut, delete, rename, or change the subscriber number of locked remote racks, devices connected to locked network segments, and certain related devices.Editing the Parameters of the Network Segment The following parameters apply to the entire network segment. The default settings are suitable for most applications. Parameters with an asterisk are used in building the bus arbiter program.
