<pdoEntry idx="60FD" subIdx="2" bitLen="32" halType="complex">

does control the enable - or at least whatever that line in the object dictionary refers to.

I have no problem sending values to the drive, and can change the value by changing the bits and 'padding' in xml file.

What I don't know is which bit(s) - what value - the drive requires to turn the outputs on. As I mentioned earlier I've mapped bits 1 & 2 to both sub-index 1 and sub-index 2 and turned both 'on.' Tried the same thing for bits 16 & 17.

I guess I could just brute-force it and try ALL the 32 bits for botrh sub-indexes.

oops should be

          <pdoEntry idx="60FD" subIdx="1" bitLen="32" halType="complex">

Also
<pdoEntry idx="60FD" subIdx="2" bitLen="32" halType="complex"> seems like it will control whether the IO is enabled or not

To test output , connect one output to your coolant in hal and see if it triggers.

ok, seems its like

<syncManager idx="3" dir="in">
        <pdo idx="1a00">
        .......
          <pdoEntry idx="60FD" subIdx="0" bitLen="32" halType="complex">
            <complexEntry bitLen="1" halPin="CW-limit" halType="bit"/>
            <complexEntry bitLen="1" halPin="CCW-limit" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-home" halType="bit"/>
            <complexEntry bitLen="13"/>
            <complexEntry bitLen="1" halPin="in-1" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-2" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-3" halType="bit"/>

            <complexEntry bitLen="1" halPin="in-5" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-6" halType="bit"/>
            <complexEntry bitLen="10"/>
          </pdoEntry>          
        </pdo>

Keep the rest of the entries there. Things like status words are important
Also make sure the total bits adds up to 32, pad out unused ones

What does:

sudo chrt 99 ping -i .001 -q -c 60000 [card_ip_address]

report? (it will run 1 minute then print statistics)

[card_ip_address] is either 10.10.10.10 or 192.168.1.121 depending on 7I76e jumpering

type:
ethercat pdos > pdos.txt
ethercat sdos > sdos.txt
and share the output here.

Probably something like

<pdoEntry idx="60FE" subIdx="1" bitLen="16" halType="complex">
<complexEntry bitLen="1" halPin="out-1" halType="bit"/>
<complexEntry bitLen="1" halPin="out-2" halType="bit"/>
<complexEntry bitLen="14"/>
</pdoEntry>


also adapted from my GitHub example

Thanks Rod, I found another example - which pointed me to your GH example. I've now got the XML and HAL configured like your example, and evern figured out how to use the "sub-index" stuff.

Remaining problem is that the manual is missing the bit values for digital outputs.

There's no corresponding chart or description for index 60FE like there is for the inputs.

I can 'talk' to the 60FEh address and write values - and see them change in the tuning software - but I've no idea what values turn on/off the outputs.

Based on the two output-related sub-indexes I'm also wondering if there's some requirement to first enable the outputs, then activate them.

I checked the OEM servo manufacturer's manual and no luck (JSS servos - JSS715N).

I tried bits 1 & 2, as well as bits 16 & 17 - based on the now-obsolete T7/leadshine servos. Wild chance, but no dice.

Also tried turning both sub-indexes on, still no joy.

I've emailed Stepperonline, no response yet.

Anyone have a suggestion?

You don't need bitslice, just do it in the xml

<pdoEntry idx="60FD" subIdx="0" bitLen="32" halType="complex">
            <complexEntry bitLen="1" halPin="CW-limit" halType="bit"/>
            <complexEntry bitLen="1" halPin="CCW-limit" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-home" halType="bit"/>
            <complexEntry bitLen="13"/>
            <complexEntry bitLen="1" halPin="in-1" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-2" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-3" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-4" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-5" halType="bit"/>
            <complexEntry bitLen="1" halPin="in-6" halType="bit"/>
            <complexEntry bitLen="10"/>
          </pdoEntry>

NOte there are some unused bits in this example

I don’t think it is Plasma/EMI related. My plasma cutter was not connected or turned on.
