Phonebook tag names must be unique within a given device. The Number parameter is used to enter the phone number that will be dialed when the tag is invoked from an OPC client application. A string of up to 64 digits can be entered. The Description parameter is used to attach a comment to this tag.
KEPServerEX5 Help 40 OPC Diagnostic Features The Find Dialog can be used to search for specific text within the diagnostics view. This aids in the debugging of a particular issue by allowing users to search for key information transferred between the client and server. For example, all actions on a particular Item ID or group name can easily be found using the search functionality.
41 KEPServerEX5 Help Each method (such as, GetErrorString) of every OPC Data Access 1.0, 2.0 and 3.0 interface (such as, IOPCCommon) supported by the server is available as a filter. Users can select a method by clicking the checkbox to the left of the method name. Additionally, users can select all methods of an interface by double-clicking the interface name. By default, all methods for all interfaces are selected. Note: Filter changes apply only to new events captured.
KEPServerEX5 Help 42 Since diagnostic information affects memory/file storage, users can decide the maximum number of OPC diagnostic events that should be captured at any specific time by modifying the Maximum number of diagnostics to capture. This value only pertains to the number of events and does not include the number of details, as the detail count for a particular event could be potentially very high. The range for this setting is 1000 to 30000. The default value is 5000.
43 KEPServerEX5 Help ability to set and query a Locale ID which would be in effect for the particular client/server session. That is, the actions of one client do not affect other clients. GetErrorString - Returns the error string for a server specific error code. The expected behavior is that this will include handling of Win32 errors as well (such as RPC errors). GetLocale ID - Returns the default Locale ID for this server/client session.
KEPServerEX5 Help 44 node (e.g. the units in a cell). QueryOrganization - Provides a way to determine if the underlying system is inherently flat or hierarchical and how the server may represent the information of the address space to the client. Flat and hierarchical spaces behave somewhat different. If the result is flat then the client knows that there is no need to pass the Branch or Leaf flags to BrowseOPCItem IDs or to call ChangeBrowsePosition.
45 KEPServerEX5 Help can be obtained from Read cache for those items and whether or not they are included in the IAdvise subscription to the group. Deactivating items will not result in a callback, since by definition callbacks do not occur for inactive items. Activating items will generally result in an IAdvise callback at the next UpdateRate period. SetClientHandles - Changes the client handle for one or more items in a group.
KEPServerEX5 Help 46 'queued' and the function will return immediately so that the client can continue to run. Each operation is treated as a 'transaction' and is associated with a Transaction ID. As the operations are completed, a callback will be made to the IAdvise Sink in the client (if one has been established). The information in the callback will indicate the Transaction ID and the error results. By convention, 0 is an invalid Transaction ID.
47 KEPServerEX5 Help IDataObject connections as in the past. EnumConnectionPoints - Creates an enumerator for the Connection Points supported between the OPC Group and the Client. FindConnectionPoint - Finds a particular connection point between the OPC Group and the Client. IconnectionPoint (Group) - Establishes a call back to the client. Advise - Establishes an advisory connection between the connection point and the caller's sink object.
KEPServerEX5 Help 48 Note: The Diagnostic Window operates in a modeless form that allows it to exist while other dialogs in the server are open.

51 KEPServerEX5 Help identical communication parameters; for example, two serial drivers cannot use COM1. For the correct communication parameters of a particular device, refer to both the manufacturer's and the driver's help documentation. Note: Flow Control settings for serial drivers are primarily used when connecting RS422/485 network devices to the RS232 serial port via a converter.
KEPServerEX5 Help 52 Note: With the server's online full-time operation, these parameters can be changed at any time. This includes changing the channel name in order to prevent clients from registering data with the server. If a client has already acquired an item from the server before the channel name is changed, the items will be unaffected.
53 KEPServerEX5 Help Report Comm. Errors turns the reporting of low level communications errors On or Off. When enabled, lowlevel errors (such as parity, framing and overrun errors) are posted to the event log when they occur. When disabled, these same errors will not be posted even though normal request failures will be. Use Ethernet Encapsulation: Many serial drivers also support Ethernet Encapsulation mode, which uses an Ethernet based serial port gateway instead of the normal PC based serial port.
KEPServerEX5 Help 54 By selecting a specific NIC interface, users will be able to force the driver to send all Ethernet communication through the specified NIC. When a NIC is selected, the normal operating system bind order is completely bypassed. This ensures that users have control over how the network operates and thus eliminates any guesswork.
55 KEPServerEX5 Help For those drivers that support it, the RTS Manual selection enables the setting of three timing parameters. These settings will only appear if the driver in use supports RTS Manual. Raise the RTS line controls how long the RTS line will be high before any data is transmitted from the communications port. The time entered is in milliseconds and has a valid range of 0 to 2550 milliseconds. The default is 10 milliseconds.
KEPServerEX5 Help 56 Note: With the server's online full-time operation, these parameters can be changed at any time. Utilize the User Manager to restrict access rights to server features and prevent operators from changing parameters. Channel Properties - Write Optimizations As with any OPC server, writing data to the device may be the application's most important aspect. The server's objective is to ensure that the data written from the OPC client application gets to the device in a timely fashion.
57 KEPServerEX5 Help 1. Write all values for all tags 'Write all values for all tags' forces the server to attempt to Write every value to the controller. In this mode, the server continues to gather OPC Write requests and add them to the server's internal Write queue. Then, the server processes the Write queue and attempts to empty it by writing data to the device as quickly as possible. This mode ensures that everything written from the OPC client applications will be sent to the target device.
KEPServerEX5 Help 58 enhancements before they are used in a production environment. Channel Properties - Ethernet Encapsulation Ethernet Encapsulation mode has been designed to provide communication with serial devices connected to terminal servers on the Ethernet network. A terminal server is essentially a virtual serial port. The terminal server converts TCP/ IP messages on the Ethernet network to serial data.
59 KEPServerEX5 Help The Network Adapter parameter's drop-down list is used to select the network adapter. The IP Address parameter is used to enter the four-field IP address of the terminal server to which this device is attached. IPs are specified as YYY.YYY.YYY.YYY The YYY designates the IP address: each YYY byte should be in the range of 0 to 255. Each channel will have its own IP address.
KEPServerEX5 Help 60 Adding a Device Devices can be added using the New Device Wizard both at the initial setup and afterwards. To do so, click Edit | New Device. Users will be prompted to enter the Device Name, which is user-defined and should be logical for the device. This will be the browser branch name used in OPC links to access the device's assigned tags. Users will also be prompted to enter a Network ID, which is a number or string that uniquely identifies the device on the device's network.
61 KEPServerEX5 Help Figure 2 - Ethernet Device Properties Device Names Device Names, which are logical user-defined names for the device, can be up to 256 characters long. The same names can be used on multiple channels. While long descriptive names are generally a good idea, some OPC client applications may have a limited display window when browsing the tag space of an OPC server. The device name and channel name will become part of the browse tree information as well.
KEPServerEX5 Help 62 parameter can be used to disable a physical device for servicing. After a device has been disabled, no communications will be attempted. From a client standpoint, the data will be marked as invalid and Write operations will not be accepted. This parameter can be changed at any time either through the menu selection or by accessing the device's System Tags. Simulate Device This parameter is used to place the device into a simulation mode.
63 KEPServerEX5 Help Device-level Ethernet Encapsulation Settings Descriptions of the parameters are as follows. IP Address: This parameter is used to enter the four-field IP address of the terminal server to which the device is attached. IPs are specified as YYY.YYY.YYY.YYY The YYY designates the IP address: each YYY byte should be in the range of 0 to 255.
KEPServerEX5 Help 64 Connection Timeout This parameter, used primarily by Ethernet based drivers, controls the amount of time required to establish a socket connection to a remote device. The device's connection time often takes longer than normal communications requests to that same device. The valid range is 1 to 30 seconds. The default is typically 3 seconds, but can vary depending on the driver's specific nature. If this setting is not supported by the driver, it will be disabled.
65 KEPServerEX5 Help will override the normal polling frequency of tags associated with the device, as well as one-shot Reads and writes. This delay can be useful when dealing with devices with slow turnaround times and in cases where network load is a concern. Configuring a delay for a device will, however, affect communications with all other devices on the channel. Thus, it is recommended that users segregate any device that requires an inter-request delay to a separate channel if possible.
KEPServerEX5 Help 66 be attempted during the off-scan period. The default setting always sends write requests regardless of the demotion period. If users choose to discard writes, the server will automatically fail any write request received from a client and will not post an "Unable to write..." message to the server event log. Note: Users can determine when a device is off-scan by monitoring its demoted state by using the _AutoDemoted System Tag.
67 KEPServerEX5 Help driver being used. To determine how an address should be entered, use the Hints button next to the Address Parameter. The address entered can be up to 128 characters in length. Once an address has been entered, it can be tested by using the Check Address button, which will then attempt to validate the address with the driver. If the driver accepts the address as entered, no message will be displayed. A popup will inform of any error.
KEPServerEX5 Help 68 connect, the server will create a virtual tag for that location and will start scanning for data automatically. To specify an optional data type, append one of the following strings after the '@' symbol: Byte Char Short Word Long DWord Float Double BCD LBCD String If the data type is omitted, the driver will choose a default data type based on the device and address that is being references.
69 KEPServerEX5 Help Note: User-defined tags support scaling. Tag Scaling This server supports Tag Scaling, which allows raw data from the device to be scaled to an appropriate range for the application. To enable Tag Scaling, select either Linear or Square Root. Scaling cannot be enabled if None is checked. The formula for both Tag Scaling types are shown in the table below.
KEPServerEX5 Help 70 data. When this occurs, the scaled value is also forced outside of the established range. To prevent this from occurring, the High and Low Clamps can be used to constrain the scaled value to the range specified. Units The server also allows a unit's string to be assigned to a scaled tag. The units' string can be up to 32 characters long. Negate scaled value This parameter forces the resulting value to be negated before being passed to the client.
71 KEPServerEX5 Help To add a new tag group to the project, right-click on either an existing device or tag group branch and select New Tag Group from the context menu. Alternatively, click on either an existing device or tag group branch and then click the New Tag Group icon on the toolbar.
