Detailed Description

A 64-bit integer register node.

Member Function Documentation

◆ create()

cvb.gevserver.Int32RegNode create ( str  name,
Optional[int]  namespace,
Optional[int]  address 
)

Creates a new 64-bit integer register node.

The node can be created using only the name with namespace or using the name only and an extra namespace parameter. You must add this node to a node map before most operations are possible.

Parameters

name : str Node name with or without namespace prefix. If the name does not contain a namespace prefix and no namespace is specified separately, cvb.gevserver.NameSpace.Custom is used.

namespace : Optional[int] Namespace to place the node in if not part of the name (see cvb.gevserver.NameSpace).

address : Optional[int] Address for this register; -1 for auto assignment.

Returns

cvb.gevserver.Int32RegNode The requested node.
