Buffer Settings

BMX ERT 1604 T buffer behavior settings can not be adjusted and they are set as follows:

  • on buffer full: The BMX ERT 1604 T module stops the recording when the events buffer is full (stop the recording).

  • on power on: New events are added to the existing events buffer if the application is the same.

    NOTE: If the application is not the same, on power on the event buffer is cleared.

  • on STOP to RUN: New events are added to the existing events buffer.

Time Stamping Variables

To select the variables to time stamp, double-click the BMX ERT 1604 T module in the drop.

BMX ERT 1604 T configuration screen:

The 16 discrete inputs are logically grouped in 4 channels (4 inputs per channel group):

Channel 0:

Time stamping function is mandatory for this channel.
Channel 4:

Time stamping function is user defined in the Function drop-down list box for this channel.
Channel 8:

Time stamping function is user defined in the Function drop-down list box for this channel.
Channel 12:

Time stamping function is user defined in the Function drop-down list box for this channel.

Each channel group needs the following parameters to be set:

  • Debounce filter type

  • Dechatter filter

For each of the 16 discrete channel, set:

  • Channel x used (Channel use is enabled or disabled)

  • Channel x debounce time

NOTE: For time stamping function channel edge event detection is set on Both edges for each BMX ERT 1604 T discrete input and can not be modified.
NOTE: More details on BMX ERT 1604 T variables settings are provided in the BMX ERT 1604 T M340 ERT Module User Manual. The variables are automatically created in the Data Editor with an ID associated.

Variables Mapping

For a BMX ERT 1604 T module, 2 cases are considered:

  • The module is located in the PLC local rack: mapping is the topological address of the BMX ERT 1604 T input time stamped.

  • 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.
