Did you run the SETPROTOCOL command in the PLC? Or did you change the PLC's baud rate settings using SETBAUD command? Both the HMI and the PLC must be set to the same baud rate, data bit, stop bit and parity configuration.
Yes SETPROTOCOL is used but it is set to 0 (auto sensing) and SETBAUD = 6 (38400).  The HMI is transmitting MODBUS ASCII, @ 38400 BAUD.

If you run the SETPROTOCOL make sure that it is set to the same protocol as your HMI. Modbus ASCII and Modbus RTU are very different and if you set it to one type of protocol it will not be able communicate properly.
I am able to use Lamp displays and watch relays and outputs fire, but can not get anything from timers, counter, or DMs.

Thank you for the help with the input condition.  

I am now having trouble reading data from the PLC using the MODBUS protocol.  I have tried setting a numeric display that is populated by a direct call to the MODBUS address as well as using a macro to get the data and then populate the display with no luck on either attempt.

Technical support / Nematron touch screen
« on: March 12, 2010, 10:48:03 AM »
I am working with a Nematron MT8070iH touch screen HMI.  I have set the PLC up as MODBUS ASCII with RS-232 communication (38400,N,8,1).  I am able to read output status from the plc but cannot write to Inputs.

If I understand correctly, no special configuration needs to be done in my code on the PLC for MODBUS communication.  And since I seem to be able to read outputs with a MODBUS address from the HMI it looks like I am correct in that thought process.

I am not sure what is going on.  I have tried different timeout settings on the HMI with no luck.

Any help will be appriciated.

I was running on JRE 1.6_xx.  After removing JRE 1.6 and in stalling the JRE 1.4-xx rev. I have successfully programed a model T100MD-2424 twice now.

I am not sure how to disable the Java auto update on this windows machine as I realy only work with MS Win at work.  Gotta Love Linux.  Some help in this regard would be cool.

Thank you very much

Technical support / RS232 PLC programming [FIXED]
« on: March 11, 2010, 08:39:17 AM »
I am having allot of trouble getting programs onto any plc using serial comm.  

I have tried to program T100MD-2424, T100MD-888+ and F2424 models from this PC.  I am running WinXP on this PC and am completely unable to successfully complete a programing cycle.   Each time I try it gets through some number of lines (not the same each time) and then the download freezes.

I have had success using my boss's laptop (also running WinXP), He is out of the office for the next week with his laptop.  If I can get this fixed It would be great I have allot of work to do.

Thank you :'(
