| Debug Info for values - enables/disables displaying information about the evaluation of:
| ||||||||||||||||||
| DP ON/OFF | Debug Pipe - shows/hides the course of communication with D2000 KOM (only if the process window is displayed on the desktop). | ||||||||||||||||||
| GETKOMARCDEPTH | Gets the timestamp of the oldest data stored in the KOM Archive. | ||||||||||||||||||
| Reads historical values from a device - StationName station. The values from the specified interval will be read. The parameter EndTime is optional and if is not entered, the current time will be used. Time format ("BeginTime", "EndTime") is "dd-mm-yyyy hh:mi:ss". This feature is supported only by some communication protocols (Datalogger ESC8800, ESC8816, UNIP_TS ...). Warning: This is not a function of KOM Archiv but it is the reading values directly from a device! NORECALC parameter causes the archive to not execute the calculation of calculated archive objects, the values of which are calculated from the values acquired by this calling of a TELL command. For some protocols (OPC DA, OPC HDA, and IEC 870-5-104), a parameter mask "M:" can be used, which is used to read the archive values only for selected I/O tags which match the mask, from the StationName station. | ||||||||||||||||||
| The command allows switching between the primary (OFF or PRIMARY) and backup (ON or BACKUP) devices for the lines of categories "SerialOverUDP Device Redundant", "SerialOverUDP Line Redundant", and "SerialOverUDP System&Line Redundant" line categories, or discovering the active device (QUERY). The active device is used to write UDP packets and packets received from it are processed. Data received from the inactive device is ignored. The third parameter (numbers 1-4) specifies the subline. For a line of category "SerialOverUDP Device Redundant", it need not be specified or can must be equal to 1. For a line of category "SerialOverUDP Line Redundant", it can be equal to 1 (the device on the Primary line is set) or 2 (the device on the Secondary line is set). For a "SerialOverUDP System&Line Redundant" category line, it can be equal to 1 - 4 (the device on the Primary/Secondary line of the system A/B is set). If an active device is detected (QUERY) and the third parameter is not entered, all active devices are listed (1, 2, or 4 depending on the line type). Example Examples of use: | ||||||||||||||||||
| The command can be used only for the lines of Serial (asynchronous serial lines) and RFC2217 Client categories. The command stops the communication (CLOSE) and disconnects the communication port. Then the port can be used by other programs, e.g. diagnostic or configuration tools. Stations on the line are to be in the Communication error state. The communication will be recovered either using the command LNSTAT OPEN or after restarting the whole communication process. | ||||||||||||||||||
| LNTRACE DEC/HEX | Enables the decimal/hexadecimal format of line listening. The default format is hexadecimal. | ||||||||||||||||||
| READKOMARC ["BeginTime"] ["EndTime"] | Reads the values from KOM Archiv. There are transferred all old values from the specified interval. The parameter BeginTime is optional and if it is not entered, the data from all history depth of KOM Archiv will be read there. The parameter EndTime is optional and if it is not entered, the current time will be used. If the parameters BeginTime and EndTime are not defined, there will be sent just the values, which have not been sent. If at least the parameter BeginTime is defined, there will be sent all values within the specified interval. Return codes:
| ||||||||||||||||||
| The command de-configures the object (line or station) and its descendants (stations, I/O tags) and reloads them. The command can be used to apply configuration changes that would otherwise require restarting the KOM process. The command is currently implemented for protocols:
| ||||||||||||||||||
| Resets the statistics of given line / station - the system structured variable SV._System_LinePerformance / SV._System_LinePerformance. It is executed immediately but it will be visible after the process D2000 KOM sends new statistics to the process D2000 Server (periodically every 10 seconds). | ||||||||||||||||||
| Dynamic change of the I/O tag address. The parameter name specifies the I/O tag. It can be entered as the object name (e.g. "M.CoolantTemperature") or the object HOBJ (the syntax requires the character '$' before HOBJ, e.g. "$278"). The parameters address1 and address2 define the new I/O tag address. Change of address will be performed only in internal data structures of the KOM process. It is not sent, in a centralized way, to the server, i.e. changed address is valid until the restart of the KOM process. After this, the value from the initial configuration will be used again. Return codes:
Dynamic change of the I/O tag address is implemented only for a limited group of communication protocols: | ||||||||||||||||||
| SETSTADDR StationName|StationHOBJ "address" | Dynamic change of station address. The first parameter specifies the station. It can be entered as the object name StationName (e.g. "B.Station") or station ID StationHOBJ. The "address" parameter defines its new address. Change of station address will be performed only in internal data structures of the KOM process. It is not sent, in a centralized way, to the server, i.e. changed address is valid until the restart of the KOM process. After this, the value from the initial configuration will be used again. Return codes:
Dynamic change of address is implemented only for a limited group of communication protocols: | ||||||||||||||||||
| SHOW TAG TagName/TagHOBJ SHOW NAN | Enables debug information for the specified I/O tag. The command requires either the name or HOBJ of the I/O tag. The debug information is usable for D2000 System developers. The SHOW NAN command displays all I/O tags whose value (current, last telemetry, or last valid) is NaN (unspecified type). | ||||||||||||||||||
| SHUTDOWN WINNT | Restarts the computer with the D2000 KOM process (the process must be running). | ||||||||||||||||||
| For the Microtel 700 protocol, it explicitly activates (ON) or deactivates (OFF) an alternative communication route for a station named StationName (e.g., "B.Station"). | ||||||||||||||||||
| Starts a data recording into a subdirectory (application directory) with the name dir_name_only. If the directory does not exist, it will be created. If this TELL command is run from the D2000 Server, firstly, the file dodm_values.dat containing the initialization values of DODM objects is recorded and then the D2000 Server will send this command to clients. Data are recorded within the time period <begin_time, end_time>. If <begin_time> is not set, data are recorded immediately. Example: These four data files (it relates to four hourly intervals) are the result of recording: Note: The TELL command uses "dd-mm-rrrr hh:mm:ss" format for the parameters of DateTime type. | ||||||||||||||||||
| Stops a data recording immediately, it is not necessary to wait for end_time. If the recording is not in progress, an error will be returned. Note: It is possible to start up this TELL command from the D2000 Server, as well as directly from the clients (currently only from the D2000 KOM and Gateway Client processes). | ||||||||||||||||||
| Starts a data replaying from a subdirectory (of application directory) with the name dir_name_only. If the directory does not exist, an error will be returned. If the command is run from the D2000 Server - at first, the dodm_values.dat file containing the initialization values of DODM objects will be recorded by the D2000 Server, and then the D2000 Server will send this command to the clients with /NOW parameter. It replays all data (in data files) with the time stamp >= begin_time. The timestamp of data represents a particular time from the recorded time period. The time of data replaying must be from the range of the recorded time period. Example of data replaying:
Note: This TELL command uses the "dd-mm-rrrr hh:mm:ss" format for the parameters of DateTime type. | ||||||||||||||||||
| Stops a data replaying immediately. If the replaying does not work, the error will occur. Note: There is possible to start up this TELL command from the D2000 Server, as well as directly from the clients (currently only from KOM client). | ||||||||||||||||||
| STDOUT output | The command redirects the standard output to a new one. Example: | ||||||||||||||||||
| STOP | Stops the D2000 KOM process. | ||||||||||||||||||
| Enables the communication (the parameter START) or disables the communication (parameter STOP) with the StationName station. The station will get the StON (START) or StOFF (STOP) value. | ||||||||||||||||||
| For protocols based on periodic polling of I/O tags (request-response protocols): the command generates one or several requests for priority reading of all I/O tags on a specified station. The Number parameter defines the number of requests, possible value is within 1...5. If the parameter is not specified, a single request will be generated. For protocols based on sending of changes (change-based protocols): the command generates one or several requests for the reading of all data. The command is implemented for a selected set of communication protocols:
