Technical support / FRAM-RTC memory addressing
« on: February 25, 2011, 01:03:31 PM »
I am using a Nano-10 in a data logging application
with FRAM-RTC installed
Memory addresses above 1024 do not seem to work.
SAVE_EEP and LOAD_EEP return 0 rather than attempted stored value.
Also EEP utility in latest TRIlogy version limits access above 1024
Is 11K words FRAM contiguous? Start address? End Address?
Please advise.

Technical support / Nano10 Network Services via COM1
« on: January 26, 2011, 12:49:49 PM »
I have a Nano10 working nicely logging events and storing files
using the Ethernet connection.
In some locations where this application would fit the nearest
jack is too far away and the wiring cost makes the project too expensive to justify.
I have found a reasonable wireless link solution: RS485 to a wireless adapter to a wireless adapter to USB to a PC where TLServer could run. This is amounts to a serial link from the Nano10 to TLServer.
Will this work? I need to store files, sync time, and possibly send e-mail

Technical support / Nano10 Remote File Services
« on: October 24, 2010, 10:25:05 PM »
When using the Remote File Services from a Nano10 to TLServer running on a PC on a LAN, it is taking over ten seconds to append a modest amount of data to a file (25 events: "door open, door closed, etc". plus hour and minute time stamps.
During this time, no scanning of inputs can take place, since the data transfer happens within a loop in a special function similar to your examples in TestEthernet.PC6.
The Timer Interrupt would appear to be a solution but it doesn't seem to work during these data transfers.
Am I missing something?
Are interrupts disabled during this time?
Is there some block transfer capability which would reduce overhead and speed up data transfer?

Technical support / API comm Library
« on: October 05, 2010, 10:08:28 AM »
I would like to develop my own GUI, starting with the well documented sample applet which you have provided.
Where can I download a copy of PLCmon.jar?

Technical support / Cursor commands on Nano10 Virtual LCD
« on: September 24, 2010, 08:07:08 PM »
The "Virtual LCD" on the web page in the Nano10 is a great feature. I'm using it to allow modification of operating parameters remotely. Effectively, it is a zero cost HMI.
It seems to work just like the real LCD, but the cursor commands are not working for me. Is this a supported feature?

Technical support / Nano10 SMTP issues
« on: September 23, 2010, 06:56:34 PM »
I have a  Nano10 doing most everything it was promised:
file services, Internet Time Server polling, even emails.
My problem is the lack of authentification when using the embedded FServer.
I have tried a number of SMTP servers, including Yahoo as in your example, with no success.
When I go through TLServer with the proper authentication
either with the older polling method or the new "tags" approach
(much more useful in my opinion) on Port#1 everything works fine (but not with on line monitoring).
A stand alone PLC without the need for an (always on) PC is an easier sell in an energy conscious "green" environment.
I'm not sure unauthenticated email is such a good thing anyway.
Are there any plans to add this feature?
Can you point me to an SMPT server which does not require authentification?
Please Note: I'm doing development and testing in a typical Linksys WRT100 environment, not using Outlook or Thunderbird
clients.

Technical support / XServer comm problems
« on: March 18, 2009, 09:48:47 AM »
When attempting to monitor a fairly complex program running on an MD100-888 after connecting to XServer I get "No Response from Node1" after initial success.

On-Line Monitoring works fine, although very sluggish, when using TLServer.

Similar problem (commexception A0, no response from PLC) when running JAVA applet xhmi1.

Tried changing baud rate to 9600...same result.

Monitoring a very simple program (continuously sampling and displaying all eight ADC inputs) seems to work fine.

Technical support / Download of Java applet for XServer
« on: March 06, 2009, 05:25:35 AM »
My Xserver, purchased in December, 2008, did not ship with any software. Rather, I was given imstructions and a password to download some utilities, which I did.
With your prompt support and my abandonment of Vista as a platform, the XServer is working nicely on my small LAN.

I now wish to try out this nifty Java applet.
Please provide download instructions.

Also, how do I reconfigure Xserver for a different LAN?
It does not seem to want to go back into config mode once it is configured.

My password for download no longer works.

Technical support / XServerConfig.exe crashes
« on: January 17, 2009, 03:45:51 PM »
Hello,

I installed XserverConfig.exe on Vista and on XP.  The program crashes on both OS when I try to run it.  I have the Xserver connected properly with the shipped cable and the Dip switch set to config mode.  I receive a Windows error: system.invalidoperationexception error.  Has anyone seen this behavior?  I have tried disabling antivirus, firewall etc.
