rchAutoConnectSet (Function)

This function controls whether a connection to the RTCU Communication Hub will be opened automatically using the primary server configuration.

The changes will take effect at device reset. (e.g. by using boardReset).

To change the fallback configuration, use rchFallbackSet or SockSetGWParm.

Input:

enable : BOOL (default TRUE)

Enable or disable auto connect.

Returns: INT

Declaration:

FUNCTION rchAutoConnectSet : INT;
VAR_INPUT
  enable : BOOL;
END_VAR;

Example:

INCLUDE rtcu.inc
 
PROGRAM example;
VAR
  parm  : rchConfigGet;
  reset : BOOL := FALSE;
END_VAR;
 
// Check the RTCU Communication Hub settings
parm();
IF NOT rchAutoConnectGet() THEN
  rchAutoConnectSet(enable := ON);
  reset := TRUE;
END_IF;
