Technical support / Windows CE & Java Runtime environment
« on: December 15, 2011, 12:45:25 PM »
Has anyone had any experience with running the TLServer and TriLogi 6.3 under Windows CE?
Is it even possible to install Java Runtime environment on this operating system?
Any help appreciated - thanks

Technical support / ADC Over voltage
« on: July 19, 2011, 08:16:24 PM »
Am I likely to get away with exposing three ADC channels on a MD888+ to  +5.5 volts for 10 minutes out of every 15?

Technical support / Communicating with proprietary UART protocol
« on: November 10, 2010, 01:43:58 PM »
I am having a few challenges getting my T100MD+ to communicate with an airconditioner control board.

The control board uses a proprietary RS485 protocol which is described as 'half duplex, each byte has 11 or 12 bits: 1 start bit, 8 data bits, 1 even parity check bit, 1 or 2 stop bits. Baud rate is 4800. Each message has 12 bytes: 1 header, 2 address, 2 command, 6 data & 1 check sum'

I  use the following commands to set  com port 3 at first scan

SETBAUD 3,42   (set RS485 to 8,1,e)
SETPROTOCOL 3,10   (No protocol)

and then use a series of OUTCOMM statements to transmit the required command strings

eg OUTCOMM 3,&H55   (send header 55H to airconditioner)
eg OUTCOMM 3,&H00   (send high address)
eg OUTCOMM 3,&H02   (send low address)
etc....

So far I have not been able to communicate with the control card. When I put an oscilliscope (PO Scope basic) on the RS485 I can decode all of the message except for the header which is being misinterpreted eg 80H instead of 55H
Am I missing the initial start bit because I am in 'no protocol'. Not sure of the implication of '1 or 2 stop bits' in the protocol

Any suggestions welcomed

Technical support / XServer file service commands
« on: February 21, 2010, 12:18:45 PM »
Can you please clarify the format & syntax of file service commands.
I have a T100MD+ connected to a XServer via Com1. The Xserver is connected to a VPN Router that has a 3G wireless card.
The PLC logs inputs from sensors (temperature, air flow, current) and records the data in a DM[] array. Periodically the plc powers up the Xserver and router, waits intill the connection is made with our LAN and then appends the data in the DM[] array to a text file on my pc. The whole unit runs on batteries so the data is collected for 6 hours before the router is fired up to conserve battery power.
Once the VPN router has connected with the LAN I can ping the XServer - no problem there. I can get ExcelLink to run and collect data from the unit in real time but I can not use this set up because of battery power restraints
Is one option is to have our LAN server 'port forward' the VPN connection to my PC?
I found a description of Remote file services in the Xserver manual that would 'point' the PLC vis the Xserver to my PC by using its IP address but I am confused about the actual syntax required. Should I be using <CONNECT> or <REMOTE> to do this? Please give an example or point me to better documentation. Thanks.

Technical support / Tri-ExcelLink error
« on: August 31, 2009, 01:45:56 PM »
Hi,
I am using Tri_excelLink 1.02 to monitor a T100MD-888+ that is collecting temperature data.

Tri-ExcelLink is collecting the data from DM[1] to DM[8] every 30 seconds. This runs fine for a while until I get the following message in Tri-excelLink:

java.lang.ArrayIndexOutOfBoundsException: 16 in S3
Access to S3suspended for 1 minute

If I stop Tri_excelLink, clear the data from the excel spreadsheet then restart the collection it will run again. So far I have had two sessions that ran for 3 to 8 hours before the error reappeared. Any tips on what is causing the error?

Technical support / Communication flow control
« on: July 09, 2007, 03:23:07 PM »
Can anyone tell me what flow control the PLC will expect from a PC that it is communicating with:
None, Xon/Xoff or hardware?

Technical support / USB to Serial port
« on: June 27, 2007, 11:01:32 PM »
The laptop I used for PLC programming and monitoring recently died. The replacement laptop does not have any serial ports but does have 4 USB ports.
I got a USB-Serial converter and can get TLServer to see the PLC, can transfer programs to the PLC but not having much success with the on-line monitoring. The link fails and TLServer reports 'poor network conditions'. The guy who sold me the converter said that it only works in about 75% of cases.

Has anyone had similar problems or any success with PCMCIA Type 2 cards that offer a serial port

Any suggestions appreciated...apart from  get another laptop with a serial port!!
I guess this also points to an issue with serial ports being phased out ....how are we going to communicate with TRI PLC's in the future

Technical support / No PLC communication with TLServer
« on: September 27, 2006, 09:31:17 PM »
Can anyone give some suggestions....

I have a MD888+ master PLC handling communications between a network of MD888+'s and the companies computer network.
The majority of the work is appending data to text files and it works just fine.

However when I use TLServer 3.0 to communicate with the master PLC I get no response eg IR* gives (Warning: No Response from PLC !). Have closed and reopened the ports - no change

When I connect using Trilogi 6.1 I can do on-line monitoring, transfer programs - the full works - communications look fine.

Any suggestions welcomed

Technical support / Trouble with 1.5.1 Java and TLserver
« on: August 01, 2006, 09:19:16 PM »
Can anyone offer some advice....

I am not able to get TLserver to run on machines that have JRE 1.5.1
Get the following error ...

C:\TRILOGI\TL5>java -jar TLSERVER21.JAR
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.5', but '1.3' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.

Unfortunately the JRE was updated to accommodate a new piece of accounting software so I cant go back even if its possible to revert versions.
Any suggestion on how to get a copy of TLserver to co-exist with Java 1.5?

Technical support / File service on PLC network
« on: July 12, 2006, 02:30:00 PM »
I am in the process of planning to network four T100MD+ PLC's that are running product test stations.
The aim is to have the PLC's report their test results back to the intranet and have results saved in a file on the network.

If I connect the PLC's together on a RS485 connection and then use a X-Server module to connect to the intranet  then the PLC's can be accessed by TLServer on the intranet - so far, so good.

The next bit I'm unsure of.
To collect information from the PLC"s I think there are two options that I'm aware of:

1 - Use Tri-Excel link to query the PLC's and read variables from them. However I only want the information to be collected once the PLC has completed a test, Tri-Excel link only appears to collect information on a timed basis (eg every XX seconds). How do I make the information collection conditional on completion of test? Would this condition have to be tested in Excel via a macro? eg collect info every 10 sec and look for a test complete flag, if flag is up then paste last data collected into spreadsheet, otherwise ignore

2 - Use  file service requests from the PLC to append data to a text file. This looks like a good solution but I am concerned that the manuals do not give an example of file services going out thru port #3 (RS485). Can I use file service requests on the RS485 network via the X-server to append files on the intranet?  

Or is there another way?

Technical support / Increasing current avaliable from analogue power supply
« on: September 27, 2005, 03:55:45 PM »
I am looking to power a sensor from the 5V reference voltage output of my MD888+.
Problem is that the sensor requires 20mA and the analogue reference voltage is limited to 10mA.

The installation manual for the PLC mentions that the 10 ohm resistor RA3 can replaced with a lower value to increase current ....what value should it be to deliver 20mA?

Thanks

Technical support / Printing from Com 1
« on: August 30, 2005, 11:56:36 PM »
Has anyone had any experience with getting a T100MD to interface with a serial printer (Canon BJC-265SP) via the COM 1 port?
Some potential problems areas are:
1- what baud rate should I be using?
2- should the serial cable be straight thru or 'null modem'


Any other pointers would be appreciated
Thanks
