VAR_INPUT
    NETID       : T_AmsNetId;
    PORT        : T_AmsPort;
    RDINFO      : BOOL;
    TMOUT       : TIME;
END_VAR

NETID : Is a string containing the AMS network identifier of the target device to which the ADS command is directed.

PORT : Contains the port number of the ADS device

RDINFO : The ADS command is triggered by a rising edge at this input.

TMOUT : States the time before the function is cancelled.

VAR_OUTPUT

VAR_OUTPUT
    BUSY        : BOOL;
    ERR         : BOOL;
    ERRID       : UDINT;
    DEVNAME     : STRING(19);
    DEVVER      : UDINT;
END_VAR

BUSY : This output remains TRUE until the block has executed a command, but at the longest for the duration supplied to the ‘Timeout’ input. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.

ERR : This output is switched to TRUE if an error occurs during the execution of a command. The command-specific error code is contained in ‘ErrorId’. If the block has a timeout error, ‘Error’ is TRUE and ‘ErrorId’ is 1861 (hexadecimal 0x745). Is reset to FALSE by the execution of a command at the inputs.

ERRID : Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs.

DEVNAME : Contains the name of the ADS device.

DEVVER : Contains the version number of the ADS device.

Example of calling the block in FBD:

In the example, the device information of the first PLC run-time system (port 801) on computer ‘1.1.1.2.7.1’ is read. As a result the name ‘PLC Server’ and the version number 02.00.7 are received.
