H0-ECOM100 and DL05 trouble

[ksmith]

I have been having some trouble with the ECOM100 and DL05.  Occasionally when I try and update the program via the ECOM, I will get an error message.  Sometimes cycling the power on the DL05 will fix the problem, other times it will not.  I saw in a previous post that this is a known problem, and one of the work around this problem is to manually put the DL05 in the program mode-load the program-then manually put it back in the run mode.  This works most of the time, but not all of the time.  I still get this error, just 2 out of 5 times.  Both have current firmware and boot files. 

When looking at the problem, I can use NetEdit and still see the ECOM, but it will fail in trying to test CPU access.

One way I get the problem resolved is to power down, remove the ECOM, power up, power down again, reinstall the ECOM, and then power up.  That works most of the time, but what a pain.

Looking a solution to this as this is going to be a standard hardware set-up for us with our new product line....and I can't have this potential error looming.

Any suggestions on a fix, better work around, or even a firmware fix (if that is the problem)?

Help....

Yes, ksmith, this is a known issue with DL05/H0-ECOM100 combination. In our tests:

(1) DL05, RUN mode, H0-ECOM100, Download ladder change: Fails about 10% of the time.
(2) DL05, PROGRAM mode, H0-ECOM100, Download ladder change: <1% (never duplicated here, but could happen)
(3) DL05, RUN mode, H0-ECOM, Download ladder change: <1% (never duplicated here, but could happen)
(4) DL05, PROGRAM mode, H0-ECOM, Download ladder change: <1% (never duplicated here, but could happen)

As you can see from our tests, the obvious "work-around" is (2), (3) or (4) until a fix can be determined. The H0-ECOM is less likely to fail.

Also, notice that when ladder changes are not being downloaded, all is stable. So you should only encounter this type of problem during development stages, and never in production (when changes are not being made).

Currently, our testing indicates a problem with the DL05 firmware. We are working with our partners, Koyo, for a fix.

Thanks for the response.  I have tried 1 and 2 in your list.  I seem to have a lower success rate than your numbers show.  I'll keep my eyes open for a firmware update.

If anyone else has another work around, please post.

Has anyone tried downgrading the firmware to 5.1 or 5.2 to see of this problem goes away?  I am using 5.3 and this is really frustrating me.  I have to deal with this problem quite a bit, even by manually putting it in the program mode.

That probably will not help, ksmith, because it is a backplane issue of which DirectSOFT has nothing to do with.

Going back to an earlier firmware did not help.

Here is my new concern....last night before I left the office, I had a 260 and (2) 05's networked and working fine via ECOM100s.  I shut the power off.  This morning when I powered the system back up, I had a problem with one of the ECOM100s and an 05-same problem that started this thread.  It appears this problem can happen just by turning the power on....that does not offer me any comfort at all---what if this happens in the field just by the customer turning on the power.  How can I help escalate this issue with Koyo and Host Eng to get a fix??  Is the ball in Koyo's court?  I need to get this resolved pretty quick as we are going to production in the next few weeks....HELP !!

For the benefit of those on the forum, we're working with ksmith on this one directly. For a work-around, we are recommending he temporarily swap out his H0-ECOM100s for H0-ECOMs to see if his problem goes away.

Any update on a firmware update to solve this problem??

Excellent timing ksmith! 

Actually, last week, I just tested new firmware for the DL05 (v5.31) and it passes the tests I did on it. I can no longer duplicate the lockup in the manner in which you experienced it. I will e-mail you the DL05 firmware v5.31 for you to test. If it works for you, let me know, and I'll inform Koyo (they are very interested in field tests), and they will release it as DL05 v5.40 firmware very soon.
