Config.ini [SYSTEM] Section Variables for Communication Drivers
The following list of variables belonging to the Config.ini configuration file’s [SYSTEM] section pertain to communication drivers and communications.
(VTScada) Indicates the maximum number of communications display lines to be displayed on the VTScada Communications Data page.
Default: 
DataLines =
100
(VTScada) Indicates the number of consecutive communication errors that need to occur when polling Data Flow RTUs before switching to the first specified backup server.
Default: BackupSwitchCount = 30
(VTScada) Indicates the color displayed when a tag is experiencing bad data quality. The default display color for bad data quality is 8 (dark gray).
Note: You can associate basic I/O tags with each other in such a way that the quality of one tag is based on the value of another (refer to the I/O tag's Quality tab). If the Quality of the associated tag is non-zero, blank, or invalid, the data quality is assumed to be good; otherwise, the data is assumed to be bad.
Default: BadQualityColor = 8
(VTScada) Indicates the color displayed for site symbols, input tags, and in the legend when communications with the site have failed. The default color is 12 (light red).
Note: The available color values are identified in Reserved Color Values.
Default: CommFailColor = 12
(VTScada) Enables you to specify the title for tags representative of installed modules. This title appears in the Tag Browser’s Type drop-down list, and on the title bar of all tag properties folders for this tag type. By default, tags representative of installed modules are titled, "Data Flow Module".
Note: Modification of the title for the Data Flow Module tags does not affect the title of the corresponding table in the tag properties database (Points.mdb). The table for Data Flow Module tags is titled "DFModule".
Default: DataFlowModuleName = Data Flow Module
(VTScada) Enables you to specify the title for Data Flow RTU tags. This title appears in the Tag Browser’s Types drop-down list, and on the title bar of all tag properties folders of this tag type. By default, Data Flow RTU tags are titled, "Data Flow RTU".
Note: Modification of the title for the Data Flow RTU tags does not affect the title of the corresponding table in the tag properties database (Points.mdb). The table for Data Flow Module tags is titled "DataFlow".
Default: DataFlowStationName = Data Flow RTU
(VTScada) Enables you to set your VTScada applications to operate in simulation mode, as though a fully-configured system is in operation. Analog Status tags will update to a random value, once every 60 seconds.
If set to 0 (default), then the simulation mode is turned off.
If set to 1, the simulation mode is switched on.
Note: The DFSimulateOn variable further enables you to enhance the simulation by mocking the transmission and reception of data from Data Flow RTUs to the application.
Default: DemoMode = 0
(VTScada) Enables you to set your VTScada applications to operate in simulation mode, as though data is being transmitted and received from Data Flow RTUs.
If set to 0 (default), then the Data Flow simulation mode is turned off.
If set to 1, the Data Flow simulation mode is switched on.
Note: Your system must consist of at least one Data Flow RTU driver tag whose selected I/O device is a serial port tag in order for the simulation to work. If the simulation is working properly, data should appear to be transmitted and received on the Communications Data page.
Note: The DemoMode variable further enables you to enhance the simulation by mocking data as if a fully-configured system with multiple I/O tags is in operation.
Default: DFSimulateOn = 0
(VTScada) Indicates the color to be displayed for site symbols, input tags, and in the legend when a site is being fast polled. The default color is 9 (light blue).
Note: The available color values are identified in Reserved Color Values.
Default: FastPollCommColor = 9
(VTScada) Indicates the duration (in seconds) for which fast polling will last once a station page has been opened. The default is 5 minutes (300 seconds).
Note: Information on poll modes is provided in the VTScada Operator’s Guide.
Default: FastPollDuration = 300
(VTScada) Indicates the rate (in seconds) at which fast polling occurs.
Note: Information on poll modes is provided in the VTScada Operator’s Guide.
Default: FastPollRate = 2
