2. Last 32 Event Messages Log: Programmed events that occur within the MP96 or on the controlled
machine are stored in a standard, last 32 event datalog. This composite log is capable of storing up to 32
entries. These entries are maintained on a FIFO basis. The log stores such pre-defined events as
mainline contactors (1-6) turning ‘ON/OFF’, power up neutral messages, OPR (Operate Relay) activity,
and much more.
3. Last Transmitted Digital Messages Log: The last transmitted digital messages log stores the most
recent 90 change messages received from the transmitter. This log shows all of the most recent operator
commands in the sequence in which they were sent. A change message refers to a change in message
data from the controller of the MP96, e.g., Parking brake released, Bridge forward, etc. This log can be
frozen by special event programming.
4. Snapshot Log: The snapshot log stores controller-transmitted data bits and the INPUT and OUTPUT
states of the decoder solid state relays to create a log. The snapshot log is activated by a triggering
event. Once this event occurs, a log is created that shows the data that was received from the
transmitting unit and the states of the inputs and the outputs of the decoder at that moment. The
triggering event for this log is defined by Cattron engineers, based on customer needs. Eight
different snapshot logs can be stored by the MP96. These logs are also FIFO-based storage. Each
snapshot contains 32 snapshot events. Some common examples of Snapshot Logs are:
• Pitch activated
• Tilt activated
• Emergency brake activated
5. Totalizer Logs: The totalizers are divided into three types of stored data. One type of log can be
generated based on the accumulative TIME an operation or state is in effect. This is useful for recording
of run times and total hours of operation of specific equipment. Some common examples of TIME
Totalizers include the following:
• Operator ‘A’ in Control
• Operator ‘B’ in Control
• Magnet Power ON
Another log can be generated based on the number of counts an output or function goes from ‘OFF’ to
‘ON’. Some common examples of ‘ON’ Totalizers include:
• Emergency switch activated
• Brake applied
• Tilt activated
The third type logs the number of counts an output or function goes from ‘ON’ to ‘OFF’. Common
examples of ‘OFF’ Totalizers include:
• Alerter timed out
• Emergency braking command
6. Equipment Specific Engineered Log (Custom Events): This custom-engineered log is defined by
Cattron engineers based on specific information provided by the user. This log will store data (using
customer terminology) and specialized states based on user needs. Up to ten of these logs can be
identified for creation by the Cattron engineer based on customer needs. For example: MAGNET POWER
ON time greater than 20 minutes, 32 events deep. Some examples of Custom Events are as follows:
