NET2000 line

The NET2000 line is used to communicate with B&R SG3 and SG4 controllers (System 2000) using the NET2000 protocol.

The following topics are covered in this section:

•NET2000 process objects

•NET2000 access types

•NET2000 event types

•NET2000 communication

NET2000 process objects

A line object, a device object, and a station object are all needed to establish a communication connection to a PLC. However, the connection is only established with the first variable object.

Process objects in the NET2000 line:

Name	Type	Connection	Usage
Line object	Line	"LNNET2"	NET2000 line
Device object	Device	Device parameter	Represents the communication device being used
Station object	Station	Station number	Represents a NET2000 station (PLC) in a network
CPU object	CPU		Can be specified, but not required.
Module object	Modules		Can be specified, but not required.
Task object	Task	PLC task name	Represents a task on the PLC
Variable object	Pvar	PLC variable name	Represents a variable on the PLC

Allowed object structure for NET2000 process objects:

NET2000 access types

The following table shows an overview of all access types which are regulated via a line. All access types not listed here as well as access types to the PVI base object are executed by PVI Manager and therefore work independently of the line being used. The corresponding process object type is listed in the "Type" column.

Access types	Type	Special features
POBJ_ACC_VERSION	Line Device	Line object: Version of the line DLL. Device object: Version of the NET2000 state machine, INA frame DLL, and device DLL
POBJ_ACC_LIST_EXTERN	Line	List of all installed (PVI Setup) NET2000 devices
POBJ_ACC_DATA	Pvar
POBJ_ACC_STATUS		Not supported

NET2000 event types

The following table shows an overview of all event types which can be generated from a line. All event types which are not listed are generated by PVI Manager and therefore work independently of the line being used.

Event types	Special features
POBJ_EVENT_STATUS	Not supported
POBJ_EVENT_PROCEEDING	Not supported
Event type > 255	Not supported
