Question:

Can Alarm Acknowledgement and Reset operations be done from the PLC?

Answer:

The Alarm Acknowledgement and Reset operations can also be executed by using the Movicon X1 system variables or by using the appropriate Basic Script functions.

The available system variables are:

• _SysVar_:InputAckAlarms = this variable when set at true executes an alarm acknowledgement. After this command has been executed, Movicon will return the variable back to false

• _SysVar_:InputResetAlarms = this variable when set at true executes an alarm reset. After this command has been executed Movicon will return the variable back to false

You can also inverse these operations so that Acknowledgment and Reset commands can be sent to the PLC.  The available System variables are:

• _SysVar_:OutputAckAlarms = this variable is set at true by Movicon when an alarms acknowledgement is executed with the button from the alarms window.  It is the programmer's job to return the variable back to false

• _SysVar_:OutputResetAlarms = this variable is set to true by Movicon when alarms an alarm reset has been executed with the button from the alarms window. It is the programmer's job to return the variable back to false

The available Basic Script functions are as follows:

• AckAllAlarms, PmeDocCmdTarget

• AckSelectedAlarms, AlarmWndCmdTarget

• AckAlarm, AlarmThresholdCmdTarget

• ResetAllAlarms, PmeDocCmdTarget

• ResetSelectedAlarms, AlarmWndCmdTarget

• ResetAlarm, AlarmThresholdCmdTarget
