Motorola IP Gateway
Not counted towards your tag license limit.
Reference Notes:
In addition to adding an IP Gateway tag, you must also install a Motorola configuration file, named MDLC_TYP.CFG. This lists the possible RTU table configurations. If there are errors in this file, you can expect "type mismatch" error messages.
MDLC_TYP.CFG is a Motorola product. It is not supplied by Trihedral.
The MDLC_TYP.CFG file must be placed in your application folder, and imported to the application using VTScada configuration management. (see: Import File Changes or Manage Files with the File Manifest.)
The Motorola IP Gateway API is made available via a Component Object Module (COM) object, ACEIPGatewayAutomation.exe. This is installed and registered on your system when VTScada is installed.
(C:\Program Files\Trihedral\VTScada Version Folder\ACEIPGatewayAutomation.exe)
The gateway will support 20 concurrent polling requests.
The ID tab of every tag includes the same common elements: Name, Area, Description, and Help ID.
Name:
Uniquely identifies each tag in the application. If the tag is a child of another, the parent names will be displayed in a separate area before the name field.
You may right-click on the tag's name to add or remove a conditional start expression.
Area
The area field is used to group similar tags together. By defining an area, you make it possible to:
- Filter for particular tag groups when searching in the tag browser
- Link dial-out alarm rosters to Alarm tags having a particular area
- Limit the number of tags loaded upon startup.
- Filter the alarm display to show only certain areas.
- Filter tag selection by area when building reports
When working with Parent-Child tag structures, the area property of all child tags will automatically match the configured area of a parent. Naturally, you can change any tag's area as required. In the case of a child tag, the field background will turn yellow to indicate that you have applied an override. (Orange in the case of user-defined types. Refer to Configuration Field Colors)
To use the area field effectively, you might consider setting the same Area for each I/O driver and its related I/O tags to group all the tags representing the equipment processes installed at each I/O device. You might also consider naming the Area property for the physical location of the tag (i.e. a station or name of a landmark near the location of the I/O device). For serial port or Roster tags, you might configure the Area property according to the purpose of each tag, such as System or Communications.
You may define as many areas as you wish and you may leave the area blank for some tags (note that for Modem tags that are to be used with the Alarm Notification System, it is actually required that the area field be left blank).
To define a new area, type the name in the field. It will immediately be added. To use an existing area, use the drop-down list feature. Re-typing an existing area name is not recommended since a typo or misspelling will result in a second area being created.
There is no tool to remove an area name from VTScada since such a tool is unnecessary. An area definition will exist as long as any tag uses it and will stop existing when no tag uses it (following the next re-start).
Description
Tag names tend to be brief. The description field provides a way to give each tag a human-friendly note describing its purpose. While not mandatory, the description is highly recommended.
Tag descriptions are displayed in the tag browser, in the list of tags to be selected for a report and also on-screen when the operator holds the pointer over the tag’s widget. For installations that use the Alarm Notification System, the description will be spoken when identifying the tag that caused the alarm.
The description field will store up to 65,500 characters, but this will exceed the practical limits of what can be displayed on-screen.
This note is relevant only to those with a multilingual user interface:
When editing any textual parameter (description, area, engineering units...) always work in the phrase editor. Any changes made directly to the textual parameter will result in a new phrase being created rather than the existing phrase being changed.
In a unilingual application this makes no difference, but in a multilingual application it is regarded as poor practice.
Help Search Key
Used only by those who have created their own CHM-format context sensitive help files to accompany their application.
Motorola IP Gateway: Settings tab
Use the settings tab to configure the primary gateway and to control the time synchronization feature.
Primary Gateway IP
Provide the gateway's primary address in this field. This must be in IPv4 format, rather than a named address.
Secondary Gateway IP
If using redundant gateways, provide the secondary gateway's address in this field. This must be in IPv4 format, rather than a named address.
System Time Sync
The enable box should be selected if you intend to use the system time synchronization broadcast, which sends the current local time to all devices on the MDLC network.
Use the Broadcast Interval control to select the appropriate timing for your system.
Motorola IP Gateway Tag Widgets
There are no widgets for the Motorola IP Gateway tag.
