How can we create a persistent, writable folder on the PPMAC to save some variables? We want them to be saved through power cycle and written to frequently.
We don't want to expose the OS to rewritable.
We want to use space somewhere on the internal memory (no USB,CF)
We have it working with a mounted cifs share but now want to move it to local to PPMAC.
Thoughts?

Also if you check the properties of the project (where you change IP and password and M,P,Q start variables) you will see the FTP user is ftp and password is ftp and there is no way to change even the password in the IDE.

Hi,
We noticed that the ftp server, specifically the vsftpd was running on our PPMAC.
We stopped the daemon
/etc/init.d/vsftpd stop
and checked that we could still upload files to the PPMAC. I also checked that we could gather and plot data.
Could you please tell me if this is a server that we still need to have running on the PPMAC and if there is some feature on the IDE which requires this server?
Thank you

Or typing something with an "r" like "rabbit" and it runs whatever program is loaded. Seems like the noshort should be the default for safety?

Thats unfortunate as many of competitor controllers come with built in web interfaces.
I am disappointed in the lack of support for the web interface (saying it's Linux and the end user should write their own is not OK), the Power PMAC is a nice product but lacking some of these high level polished refinements.

We are dealng with the same problem where commands that dont return anything are hard to queue and dequeue. We also used the trick of adding P0 to each command to force a return from ppmac.
-
Last time i tries to build the web project from the source on the ppmac it turned out it was missing files and not buildable. I think it doesnt work in version 1.5.8 and newer. I also get the name on the title bar but no page data.

newer firmware allows the rotary buffer to stall gracefully without giving runtime errors.

Hello
We are trying to all work on one machine with one PPMAC device. We are all able to connect the IDE via the same IP address on our network however after about 3-4 connections, additional attempts to connect fail. How many simultaneous connections can there be to a PPMAC on the IDE and/or Asynch connection?
Is there a way to increase this count in the PPMAC if it is a limit?
Thanks
-
didnt think you could define both of these?
#define _EnumMode_
#define _PPScriptMode_

Does this need the extra ethernet card because the ethernet chipset on the PMAC460CPU is not compatible with the EtherCAT library and the external one is compatible, or is there actually Beckhoff chip hardware on the external ethernet card?
Will future PMAC cards eventually have the ethercat built into the main ports:?

Hello
I want to be able to use the PeWin32Pro to compile the PLCs and create the download file but 1)not actually download (I see this option in the IDE) and 2)not have a real PMAC actually connected.
This allows us to compile and create released versions at a desk rather than at a machine. I had heard there was a registry setting that would allow this to be done?
How can we manage this operation?
Thanks

Can you elaborate on how you setup your Eclipse IDE to compile for PPMAC and automatically download? It would be very helpful to us.
Thanks
pmurcutt - If you're looking for a C++ capable IDE, I've had good success using Eclipse CDT for both C and C++ on the Power PMAC. You can even use the Remote Systems plugin to automatically download your executables after a build, so it's pretty seamless. YMMV.
-
And have you had a chance to "convert it to a background C program." We would be very interested in that program. :-)

hbausley We need to add an IP Route to our device and I cannot seem to be able to save it. I can manually type it at the command prompt as follows ip route add 192.168.0.2 via 192.168.0.10 and I can confirm it took by typing "route" and viewing. I cannot figure out where it needs to get put so that on reboot it runs the command each time. I've tried adding it to the end of the /etc/interfaces file but that doesnt seem to work. Is there a script somewhere I need place this command?
-
I put them on the same network and updated the route table and it works now, with the exception that the route table doesnt seem to be saved after reboot. How do I permanently save the route table?
Thanks everyone for your help.
-
how do you save the route table from reboot to reboot? I've made changes to add a static route but when I reboot they are lost.

I followed the instructions on the link hbausley sent me and ended up bricking my PPMAC for a short while. I found in another thread to mount the flash as windows drive with a USB and that worked. Now both interfaces eth0 and eth1 come up but I still cannot get the eth1 to connect to the WAGO modbus module.
Here is my configuration.
eth0 set to ip 172.16.150.200
eth1 set to ip 172.16.150.251
Wago set to ip 172.16.150.250
All are set to static IP's. the gateway on all is set to 172.16.150.1 and the masks are 255.255.255.0
I can login to both eth0 and eth1 from anywhere on the network but once into PPMAC a ping to the WAGO fails unreachable. Also if I unplug eth1 and only have eth0 plugged into the network from anywhere on the network I can ping eth1 @ 172.16.150.251 successfully even though its not plugged in physically??
Thoughts?

It comes with the standard IDE install. Its in the sample projects folder.
Modbuslib example and PowerPMACModbus example
Neither one compiles for me, but then neither does a blank new project so its probably not the Modbus example.
Where is this "demo Modbus example"?

Sina
Thanks, I changed the IP address of the WAGO to be on the subnet with the PPMAC and changed the PPMAC IP address to be on our server and the two seem to be playing nice.
I have a new problem now where I cannot seem to compile the demo Modbus example. It gives me errors about gplib.h. I even tried creating a default project solution and compiling and it also complains about gplib.h.
Thanks
MClement,
I tried a similar setup to yours and I can ping the ip 172,16.100.254 from my Power PMAC with static IP of 192.168.0.200 on eth0.
Since you also mentioned that you can ping 172.16.100.65, I would assume we have to look for the problem somewhere else.
How about if you change your Power PMAC IP address to the same subnet as your other devices?
Check this post for help on how to change the IP address: http://forums.deltatau.com/showthread.php?tid=572

Should the Modbus be put on the second ethernet jack on the PowerPMAC or does it matter if its physically plugged into a network remotely? Im not sure if it makes a difference but should the WAGO unit be setup with an local to the PPMAC IP address with crossover cable (ie 192.168.0.201) or can it be on a real network with an actual IP?

Hello
We are trying to use a WAGO Modbus TCP module with our PowerPMAC. We currently have the following setup:
PowerPMAC setup with eth0 (first jack) at 192.168.0.200 on our server (172.16.100.XXX) via a hub. We can telnet or IDE from any computer on our network at 192.168.0.200 and connect to PPMAC fine.
Wago 750-352 Modubus TCP module setup on static IP 172.16.100.254 on the same hub. The Wago can be pinged, connected from any computer on our network.
When telneted into the PowerPMAC as root a command of "ping 172.16.100.254" fails. A "ping 172.16.100.65" command is successful (this IP is another computer on our network).
I also noticed that a command of "ifconfig" doesnt list the eth1 port at all, just the eth0 and lo.
Thoughts????

Thanks for taking the time to work with Axis. We certainly appreciate Delta Tau's assistance.
Thanks

We are using the PHMI with the Pcommserver.exe system and have noticed that if/when the Pcommserver crashes or is manually killed from the task manager, the PHMI memory useage runs away up to around 2GB. PEWin32pro does not exhibit this behavior.
What is going on under the hood when the handle to pcommserver dies that causes PHMI to ramp up the memory like that? Is there no mechanism that causes PHMI to restart pcommserver or to halt when it loses connection?
Thanks

Email sent....Thanks Monica
Our current lead time is 6 to 8 weeks, not including our holiday shut down the week of December 25th. Please let me know who you are working with at Axis, so I can work with them to try and improve delivery. You can reach me via email: monica@deltatau.com. Hope to hear from you!
How to create a writable mount point??
in Power PMAC

And how are you doing the sync?
We definitely want it to persist. We are writing to it maybe once every handful of seconds.
