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.

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 :'(
