I can probably help you. Contact me at [email protected].

Dan Michael

 

Prosoft publishes a very well documented example program for the MVI56-MCM module. I think it even comes on disk with the module itself.

http://www.prosoft-technology.com/content/view/full/2717

This example program covers both receive and transmit functions of the module. I usually reduce it's functionality to fit my particular application.

 

Hello,

Equustek build external Modbus to DH+, DH-485, or Serial DF1 converters. Eliminating the need for in rack converters with complex programming. http://www.equustek.com
DL3500-Modbus/DH+ or DH-485.
DL4000-DMX.

Regards,
Andrew

 

Mr. Andrew
I have some problems using an external Modbus RS485 to DH+ converters (Equustek DL3500-Modbus/DH+ or DH-485). http://www.equustek.com
Have you ever use this device?
I'm trying to get communication (read data) from a Modbus RS-485 2-wire device (Multitrend Plus V5) to a ControlLogix 1756 through 1756-DHRIO, using MSG Instructions.

I read your reply in www.control.com, So you can probably help me on this.

I'd really appreciate your help as soon as possible.

Regards.
