ADSRDDEVINFO

The function block reads the general device information.

Inputs

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

Name	Type	Description
NETID	T_AmsNetId	String containing the AMS network ID of the target device to which the ADS command is addressed (type: T_AmsNetId).
PORT	T_AmsPort	Port number of the ADS device (type: T_AmsPort).
RDINFO	BOOL	The ADS command is triggered by a rising edge at this input.
TMOUT	TIME	Indicates the time before the function is canceled.

Outputs

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

Name	Type	Description
BUSY	BOOL	This output remains TRUE until the function 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. Note that it is not the execution of the service but its acceptance whose time is monitored.
ERR	BOOL	This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in ERRID. If the function block has a timeout error, ERR is TRUE and ERRID is 1861 (hexadecimal 0x745). Is reset to FALSE by the execution of a command at the inputs.
ERRID	UDINT	ADS error code or command-specific error code of the last executed command. Is reset to 0 by the execution of a command at the inputs.
DEV NAME	STRING	Name of the ADS device
DEVVER	UDINT	Version number of the ADS device

Example of calling the block in FBD:

ADSRDDEVINFO 4:

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.
