|Question:||Is it possible to achieve more consistent I/O updates for high speed applications with the Mechatrolink Phoenix Bus Coupler and the MP2000 series products? |
|Answer:||There may be a delay in the in IO response when using the Phoenix bus coupler over the Mechatrolink. This could be caused by a large amount of IO being used and the time it takes for the Mechatrolink to update the IO status.|
As a result we recommend a phased approach to improve the IO responsiveness with the following steps:
1. I/O connected to the main body of the coupler will be faster than the additional slice I/O because of the additional time required by the backplane for processing of the remote I/O. Use main body I/O where possible for the most critical I/O.
2. Update the module's update rate to sync with the High speed scan program being used. If using an MP2000iec controller, be sure the I/O driver is set to update at an appropriate interval (synchronize with a task that corresponds to the desired I/O refresh rate.)
3. Move the critical I/O to an LIO card on the MP2000 series controller.
4. Move the critical output to the COIN connection on the LIO or CNTR-01 card. This is also referred to as the High Speed Output function on MP2000iec controllers. This is a hardware level function that can operate the output within 13 uSec of the encoder on the LIO card meeting an exact position value.
