Accessing F-PRO Event Information
All F-PRO detector event messages displayed in the Event Log are available via Modbus. The following
controls are available.
Refresh Event List (Function Code 6, address 40513): Fetches the latest events from the
F-PRO's event log and makes them available for Modbus access. The
most recent event becomes the current event available for reading.
Acknowledge Current
Event and Get Next Event (Function Code 6, address 40514): Clears the current event from
the read registers and places the next event into them. An
acknowledged event is no longer available for reading.
Get Next Event (Function Code 6, address 40515): Places the next event in the
read registers without acknowledging the current event. The
current event will reappear in the list when Refresh Event List is
used.
Size of Current Event
Message
(Function Code 3, address 40516): Indicates the number of 16 bit
registers used to contain the current event. Event data is stored with
two characters per register. A reading of zero indicates that there are
no unacknowledged events available in the current set.
(Note: The Refresh Event List function can be used to check for
new events that have occurred since the last Refresh Event List.)
Read Event Message (Function Code 3, addresses 40517 - 40576): Contains the current
event message.
Two ASCII characters are packed into each 16 bit register. All
unused registers in the set are set to 0.
