VAR_INPUT

sNetId           : T_AmsNetId;
sMLGWClientName  : STRING(80);
bExecute         : BOOL;
tTimeout         : TIME := t#5s;

sNetId: AMS Net ID of the target device on which the TwinCAT Bang & Olufsen Server is operated.

sMLGWClientName: Name of the Masterlink Gateway Client whose connection status is to be read.

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

tTimeout: Indicates the time before the function is cancelled.

sMLGWClientName convention Upper/lower case is ignored Letters and numbers No special characters or umlauts, except “_” (underscore) Minimum length 1 character Maximum length 80 characters

VAR_OUTPUT

bBusy                       : BOOL;
bError                      : BOOL;
udiErrorId                  : UDINT;
eMLGWClientConnectionState  : E_MLGWClientConnectionState;

bBusy: This output remains TRUE until the block has executed a command request, but at the longest for the time period applied at the tTimeout input. No new commands are accepted at the inputs as long as bBusy = TRUE.

bError: This output is switched to TRUE if an error occurs during the execution. The command-specific error code is contained in udiErrorId. If the function block is called again with TRUE on bExecute, then bError is reset to FALSE and udiErrorId to 0.

udiErrorId: 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.

eConnectionState: This output is set to eMLGWClientConnected as soon as the connection is established. If there is no connection the output is set to eMLGWClientDisconnected.
