Re: Smaract MCS2 position polling issue

[Jeffrey Gamsby via Tech-talk <tech-talk at aps.anl.gov>]

It seems as if the threshold is 5 axis, 

MCS2CreateController("MCS2", "MCS2_ETH", 5, 100, 100)

this works fine, but as soon as I go to 6 or above, I have delay problems.

I have tried setting the SCAN value to .1 second, I have tried changing the active and idle poll periods, but so far no luck.

Hi,

This is my first post and I'm relatively new to EPICS. 

I am trying to use an MCS2 Smaract Controller with 9 axes, the issue I am having right now is the performance on the position information. 

The relevant config file seems to be the smaractmcs2.iocsh and this is what I'm using:

# PORT, MCS_PORT, number of axes, active poll period (ms), idle poll period (ms)

MCS2CreateController("MCS2", "MCS2_ETH", 9, 100, 100)

It's taking more than 30 seconds for moves to complete (using DMOV), even for repeat moves that should not go anywhere.

Ideally I would want position updates for each axis in the ms range, how can I troubleshoot and solve this problem?

Thanks,

Jeff
