The MARC Multii-Port can make this translation for you. Click this link for a datasheet http://www.miille.com/din366-10p.pdf

Thank you,

What PLC?

If the PLC supports Modbus RTU for sure it supports Modbus ASCII too.

You need just to configure the communication port in the right way.

So what PLC is it?

Please look at our options for converting Modbus ASCII to Modbus RTU: You could use our Multii-Port module
http://www.miille.com/din366-10p.pdf

or our Omnii-Comm
http://www.miille.com/din266-p00.pdf

There are some trade-offs between the modules but both will do what you need to do; convert Modbus ASCII to Modbus RTU. Please contact me at jmiille at miille. Com if you have additional questions or visit us at http://www.miille.com

Thanks,

Jerry Miille
