Here's a suggestion to myself - Read the FAQs first.

Technical support / Java Version Compatibility
« on: October 17, 2004, 08:28:19 AM »
Have been using TLserver 2.0 with JAVA RTE as recommenced by TRI-PLC.
Corporate IT dept upgraded all users to JAVA 2.x RTE (we have no choice) and now TLserver 2.0 will not run.
Is TLserver compatible with the newer JAVA RTE versions?
Any suggestions?

Technical support / Re:rs-485 burnt
« on: July 29, 2004, 06:09:50 AM »
I have fried two PLCs in the manner you describe. I attribute this to a ground loop differential between comm1 and comm3.
I am now using an opto-isolated RS485 controller on comm1 to control digital devices and a similar opto-isolated RS485 on the PLC comm3 line to my PC's RS232 port.
At the same time I received a shock from my IBM thinkpad chassis (which was connected to PLC comm3 via an un-isolated 485 convertor)
Since switching to the opto-isolated converters I have had no problems. I got then from www.rs485.com for about $70.00
Good luck!

Technical support / Re:Setting PLCID using Tbasic
« on: July 09, 2004, 05:44:14 AM »
OK, I'll work around it.
My plan was to use a dip switch to set the address in a multidrop system but I can do it with the server.

Technical support / Setting PLCID using Tbasic

Is there a way to set the PLC ID using Tbasic? If no TBASIC command that does this directly is there an eprom address that can be modified?
If so please provide an example.
many thanks.

Thanks Joel,
I had come to the same conclusion re: the editor.

I may not be educated enough to understand your reply so I'll re-phrase my question.
If I:
Define a custom function (dcusfunct)
Insert a ladder circuit
insert a n.o. contact
associate the new contact with the cusf name
insert an output (eg out8) so that the output activates when the cusf contact closes.
How do I get the cusf contact to close so that out8 will activate?
I can send a PC5 file if needed.

Technical support / Custom Function as ladder contact?
« on: January 29, 2004, 11:19:18 AM »
I can add a ladder contact and assign it to a custom function....
but I cannot find any TBASIC reference that explains how to change the logic state of the contact.
Is the N.O. contact shut while the function is executing?
I think my VB6 experience is causing a conceptual problem.
