The example ladder logic defines a 5-element array of the MVI69103M_Event
objects to hold the data received in a single 9903 block. Ladder logic to handle a
9903 block is shown in the following figure:
This simple logic does not use the message count parameter in the block and will
not work for most applications. It is only provided as an example to display how
to move the 9903 data to a user controller tag. If the message pass-through
feature is utilized, more logic is required to store the messages received. This
feature is most commonly utilized to pass events from the controlled device to an
event logger connected to the processor.
3.1.7 Data Object (MVI69103M_Clock)
This type is used to copy the date and time information between the MVI and the
processor through optional block 9970 and 9971. Please refer to the sample
ladder logic (on the ProSoft Solutions CD) for further information about this
feature.
