Alarm Handling

Variable Setting

Automatic handling

vPN_MGMT_OUTPUTS.IOD_MGT_ALARM[device index] = 0

Manual handling

vPN_MGMT_OUTPUTS.IOD_MGT_ALARM[device index] = 1

If automatic handling has been selected for an IO-device, the IO-controller automatically acknowled-

ges each alarm received from the respective IO-device and the alarm indication flags

'vPN_MGMT_INPUTS.IOD_ALARM_IND' are not used. If manual handling has been selected, an

alarm indication is passed to the PLC program by setting the bit with the index of the respective IO-

device in 'vPN_MGMT_INPUTS.IOD_ALARM_IND[device index]'.

Call FB 'Alarm_Request'

The input 'ID' contains the IO-device number '22'. By setting M30 the alarm request is started. M31

indicates that the requested data has been written to the global variable 'Alarm_data1'. This function

block accesses the global variables 'vPN_MGMT_INPUTS' and vPN_MGMT_OUTPUTS.

8.1.6 Function Block 'Alarm_Ack'

This function block sends the 'acknowledge alarm' frame to the IO-device.
