FC10: AL_MSG - error and operating messages

Function
With block FC10 "AL_MSG", the signals entered in DB2 are evaluated and displayed as
incoming or outgoing error messages and operating messages on the user interface.
The incoming signals (positive edge) are displayed immediately in the case of both error and
operational messages.
Outgoing signals (negative edge) are deleted immediately only for operating messages. In the
event of error messages, the messages that are no longer pending are only deleted with the
parameter "Quit", i.e. errors remain displayed on the user interface until they have been
acknowledged by the user even if the signals are no longer pending.
The "ToUserIF" parameter can be used to transfer the group signals for the feed, read and NC
start disabling signals and feed stop signal to the existing axis, spindle and channel interfaces.
The group signals are transferred to the user interface directly from the status information in
DB2 irrespective of an interrupt acknowledgment.
1. If parameter "ToUserIF" = 0, there is no transfer of the signals to the user interface. In this
case, the user must take measures in his PLC program to ensure that these signals are
influenced in the interface.
2. If parameter "ToUserIF" = 1, all signals listed above are sent to the user interface as a group
signal in each case. The user PLC program can, therefore, influence these signals only via
DB2 in conjunction with a message or interrupt output. The appropriate information is
overwritten in the user interface.
Alternatively to the response described in paragraph 2, the disable and hold signals can be
influenced without a message being output by influencing the interface signals with a disable
or stop signal state after FC10 is called.
The following program illustrates this method:
CALL FC10(
ToUserIF :=
Ackn :=
1010
Start := I 45.7,
ChanNo := 1,
IntNo := 1,
Active := M 204.0,
Done := M204.1,
Error := M 204.4,
StartErr := M 204.5,
Ref := MW 200);
TRUE,
I 6.1);
//Start an asynchronous subprogram
//in channel 1 interrupt number 1
