FB_exit

Syntax

Method FB_exit : BOOL

Variables, which are given at the input of FB_init, could be online changed after this method has been called. Normally this method can be used to dynamically make connections to multiple Q-SYS cores.

Example:

Switch the target server from “192.168.0.110” to “192.168.0.100”:

PROGRAM MAIN
VAR
    fbConnect           : FB_Connect(‘’, ‘192.168.1.110’, T#15S, fbResExtract); 
    fbResExtract        : FB_QRC_ResExtract;
    nStep               : INT; 
    bChangeTarget       : BOOL;
END_VAR

CASE nStep OF 
    0:
        fbConnect.Connect();
        IF NOT fbConnect.bBusy AND NOT fbConnect.bError THEN
            nStep := nStep + 1;
        END_IF
    1:
        IF bChangeTarget THEN
            bChangeTarget := FALSE;
            nStep := nStep + 1;
        ELSE
            nStep := 3;
        END_IF
    2:
        fbConnect.FB_exit(FALSE);
        fbConnect.FB_init(FALSE, FALSE, '', '192.168.0.100', T#15S, fbResExtract);
        nStep := 0;
    3:
