Re: [etherlab-users] Master0 dead

2017-04-18 Thread Gavin Lambert

The "waiting for devices" state means that no network devices are available for 
EtherCAT yet.

You need to check your configuration file (if you're using SysV 
/etc/init.d/ethercat then the file is /etc/sysconfig/ethercat; if you're using 
SystemD ethercat.service then the file is /etc/ethercat.conf).  You need to 
define both the driver module to use (which one depends on what network 
interface you have) and also define the MAC addresses of each interface that 
should be used for EtherCAT communication.

Re: [etherlab-users] experience with CU1128 | EtherCAT junction

2017-04-18 Thread Gavin Lambert

I have one in a test system (though not using it in production) and it works
fine.  As Graeme said it basically just works without configuration, though
if you're specifying devices by network position then you need to be careful
about the ordering, since it will appear at three different places in the
network.

There's two aspects to Hot Connect.  One is the hardware auto-link and
network rescan that the slaves and the master do automatically.  The other
is configuring your application and network model accordingly.  If you want
to take advantage of it, you really should have at least the first slave in
each hot-connectable group have an alias address rather than a
position-based address and you should use separate domain groups for each
hot-connect group.  (Or alternatively don't rely on the domain WC state and
instead use some per-slave process data to determine if it's online or not.)

Re: [etherlab-users] experience with CU1128 | EtherCAT junction

2017-04-18 Thread Graeme Foot

Never used them, but just had a quick look at the doco (just cos I was curious).

- It mentions the ability to Hot Connect any of the ports, but there's no 
configuration behind this, just the usual hardware support.
- It is detected as three ESC's (as that's what it has internally), each one 
being identified by a different RevisionNumber (but same product code)
- Primary ESC 1:  ProductCode="#x04685432" 
RevisionNo="#x0001"
- Sub ESC 2:  ProductCode="#x04685432" RevisionNo="#x00010001"
- Sub ESC 3:  ProductCode="#x04685432" RevisionNo="#x00010002"
- It can be used as a distributed clock reference clock
- There's no PDO or CoE data / configuration

So I would expect you just need to set up three slaves as above, then the 
master can report on the status of their ports (via reg information).

One thing to note is that TwinCat knows that the sub ESC's are sub devices but 
I don't think the EtherLab master supports this, so you may need to place Sub 
ESC 2 and Sub ESC 3 further down your list of slaves.  (i.e. Sub ESC 2 after 
the devices connected to port 3, and Sub ESC 3 after the devices connected to 
port 5.)  See page 12 for a diagram on how the ports relates to the the three 
ESC's.

It seemingly looks like a dumb device, but the documentation hints at

[etherlab-users] experience with CU1128 | EtherCAT junction

2017-04-18 Thread Matthieu Bec

Hi,

Has anyone had experience using a "CU1128 | EtherCAT junction" from Beckhoff 
(*) with the etherlab master?

It seemingly looks like a dumb device, but the documentation hints at 
particular steps to set it up with TwinCAT:

```
Topological configuration
With the CU1128, special attention should be paid to the sequence of the 
EtherCAT slaves. Since the CU1128 has 7 junction ports, drop lines connected to 
ports must and can be clearly identified in practice. If incorrect information 
is provided in the configuration (TwinCAT System Manager file *.tsm), the 
system cannot start.
```
