Buffer Settings

BMX CRA 312 10 buffer parameters are set on the Modicon X80 drop. Double-click the EIO Modicon X80 drop in the remote drop and click the Time Stamping tab:

The BMX CRA 312 10 Time Stamping settings are as follows:

Parameter

Value

Comment

On buffer full

Stop the recording

(Default value)

Stop the recording when the events buffer is full.

Overwrite buffer

The oldest events are overwritten when new events occur and the events buffer is full.

On power on

Reset the local buffer

The events buffer is cleared.

Nothing

(Default value)

New events are added to the existing events buffer if the application is the same. If the time stamping application is different, the buffer is cleared.

On STOP to RUN

Reset the local buffer

The events buffer is cleared.

Nothing

(Default value)

New events are added to the existing events buffer if the application is the same. If the time stamping application is different, the buffer is cleared.

Time Stamping Variables

Each input and output of discrete modules located on a Modicon X80 drop with a BMX CRA 312 10 can be time stamped.

To select a discrete module for time stamping, proceed as follows:

  1. double-click the discrete module in the remote drop

  2. select the Device DDT tab (the implicit device DDT name attributed by default to the device is mentioned in this tab)

  3. click Goto details command button, the Data Editor window opens

To set a channel time stamping parameter for the discrete module chosen, proceed as follows:

  1. in the Data Editor , click the + beside the implicit device DDT name that corresponds to the discrete module you want to set in order to display the module elements

  2. click the + beside DIS_CH_IN or DIS_CH_OUT elements to display each channel parameters.

  3. click the + beside the channel to be set

  4. in the VALUE parameter line, double-click in the Time stamping cell to set the event detection edge. Selecting the edge enables the channel for time stamping.

Variables Mapping

As the module is located in a Modicon X80 drop, mapping is provided by device DDT. The I/O time stamped module location is used (for example \2.1\0.1 means: bus 2 (RIO), drop 1, rack 0, slot 1).

An alias can also be associated with a time stamped variable in device DDT.
