Y_AX_ControllerAlarm

This function block provides a BOOL output to indicate if there is a controller alarm not related to an axis. It uses the Y_ReadAlarm function block and determines if the AlarmID output is non-zero. This function is useful because the PLCopenPlus function Y_ReadAlarm does not have a Boolean output, just the AlarmID.

Parameters:

*	Parameter	Data Type	Description	Default
VAR_INPUT
B	Enable	BOOL	The function will continue to execute every scan while Enable is held high and there are no errors.	FALSE
VAR_OUTPUT
B	Valid	BOOL	Indicates that the function is operating normally and the outputs of the function are valid.
V	Alarm	BOOL	Indicates if the controller has a non-axis related alarm.
V	AlarmID	UDINT	This output provides the Controller Alarm ID. This output is reset when execute goes low.
B	Error	BOOL	Set high if an error has occurred during the execution of the function block. This output is cleared when 'Execute' or 'Enable' goes low.
E	ErrorID	UINT	If Error is true, this output provides the Error ID. This output is reset when 'Execute' or 'Enable' goes low.

Notes:

As the PLCopen manual displays the AlarmID values in hexadecimal, it is best to view the AlarmID value of this function block in hex.
