Communication Driver Tags
Communication driver tags are designed to translate data being transmitted to and from specific types of I/O devices, such as PLCs and RTUs. Each brand of I/O device generally requires its own communication driver, depending upon the communication protocol used by the device.
The following communication driver tags are included with VTS:
Allen-Bradley Driver Tags CIP Driver Tags
Data Flow Module Tags Data Flow RTU Driver Tags
Dataradio Diagnostic Driver Tags DDE Driver Tags
MDS Diagnostic Driver Tags Modicon Driver Tags
Omron Host Link Driver Tags OPC Client Driver Tags
Siemens S7 Driver Tags Polling Driver Tags
Note: Please note that Trihedral Engineering Limited has many other communication driver tags available. Please refer to the VTS driver library for further information (see VTS I/O Device Driver Library).
The basic driver tag types allow VTS to provide an interface to:
• Physical I/O devices, such as programmable logic controllers (PLCs), RTUs, and I/O boards; and
• Windows system features, such as Dynamic Data Exchange (DDE).
Most driver tags have 7 variables which can be logged. These are described in the following section.
