|
It is the role of analog control tags to transmit analog data entered by the user to an I/O device. | |
|
The role of analog input tags is to represent incoming analog data values from equipment processes | |
|
It is the role of analog outputs to take analog data from the user or from another tag, and write it to an I/O device. | |
|
It is the role of analog status tags to take analog data from an I/O device. | |
|
The calculation tag type is used to wrap an expression, with the resulting value of the calculation tag being the result of the expression. This new tag type replaces the older function tag type. | |
|
These tags provide an interface between VTS and hardware that uses the CIP and/or ENIP standards for communications. | |
|
Counter tags provide a means to count events such as pump starts or equipment cycles. | |
|
Data Flow module tags enable you to represent the installed modules for a Data Flow RTU. | |
|
Data Flow RTU drivers are used to provide an interface to a Data Flow RTU. | |
|
These tags enable users to read statistics from any given Integra-TR or Integra-H Dataradio unit. | |
|
The DDE driver allows tags to read from and write to a local or network DDE server. | |
|
Deadband control tags monitor the value of any tag with a numeric value and compare the monitored tag's value to a low set point and a high set point. | |
|
Digital control tags transmit digital data entered by the user or from another tag and write it to an I/O device. | |
|
Digital inputs represent incoming digital data values from equipment, and provide drawing methods that change color, appearance, or text to impart the value of the digital input and associated equipment. | |
|
Digital output tags take digital information from the user or from another tag and write it to the I/O device. | |
|
Digital status tags accept incoming digital data from an I/O device. | |
|
The DNP driver is a DNP 3.0 Master that implements all the objects defined in DNP subset level 3, except for the "Frozen Counter" type. | |
|
Driver multiplexer (DriverMUX) tags allow you to set up redundant lines of communication between I/O tags and equipment. | |
|
The font style tag type is used to specify fonts for the drawing tools that employ text. | |
|
The function tag type is used to perform mathematical and logical calculations using numeric values and/or the values of other tags. | |
|
The logger tag type monitors the value of another tag and records that tag's data in RAM as well to a disk file. | |
|
These tags enable users to read statistics from any given MDS radio. | |
|
Modem tags represent a physical modem for your system, and enable outgoing and incoming calls. | |
|
The Modicon driver provides an interface to a Modicon PLC, allowing communication via: | |
|
|
• Serial RTU |
|
|
• Serial ASCII |
|
|
• SA-85 I/O card for ModBus Plus communications |
|
Network status tags enable you to view the connectivity of up to two workstations, allow you to trigger an alarm should a monitored workstation become disconnected, and enable you to log this data to file. | |
|
The notebook tag type enables users to add notes on the Historical Data Viewer page. | |
|
The Omron Host Link driver provides an interface to an Omron PLC via a serial port. | |
|
The OPC Client driver allows VTS to act as an OPC Client to an OPC Server, enabling the exchange of data from a VTS application to an OPC Server. | |
|
Polling driver tags provide controlled communication between drivers and ports. | |
|
Pulse input tags accept incoming analog data from a pulse input device (such as a rain gauge, transducer, or a gas, water, or electric meter). | |
|
Pump status tags accept incoming digital data from pumps. | |
|
The realm display setup tag is used to control what options are available to a VTS Internet Client for managing its own screen parameters and appearance. | |
|
The report tag type is used to track the data of a user-defined group of tags to a user-defined output format at regular intervals. | |
|
Roster tags are designed to work with the VTScada call-out system. Using a roster tag, you may configure contact information for up to 8 operators | |
|
A script tag monitors the value of another tag and allows the execution of a script when the monitored tag's value changes. | |
|
Selector Switch tags provide the means to create three-position switches that can be used (among other things) for implementing Hand-Off-Auto (H-O-A) switches. | |
|
The serial port tag type opens a serial port for use by a driver. | |
|
The Siemens S7 driver provides an interface to Siemens PLCs of the following types: | |
|
|
• S7-200 |
|
|
• S7-300 |
|
|
• S7-400 |
|
SQL Logging allows you to record in an ODBC compatible database, the values from any tag that could normally be logged. | |
|
The SQL Logger tag type allows you to select where data that is to be logged is to come from. | |
|
The TCP/IP port tag type enables you to connect your VTS application to a series of hosts, allowing you to transmit data across a network or over the Internet. | |
|
The totalizer collects the integral of another tag's value over a time period. | |
|
This tag type can be substituted for a TCP/IP port tag for a driver to allow serial drivers to transparently use UDP/IP. | |
|
Workstation status driver tags can be associated with one or more analog input tags to access data that the driver obtains from the Windows Management Instrumentation (an API in the Windows operating system that enables devices and systems in a network to be managed and controlled) |
