Modbus Application Note/Paper


Karl Oct 30, 2009 08:51 PM

We have supported the Modbus protocol for quite a few years, and the use of this protocol in our dataloggers seems to be increasing. Therefore, as many of you who use the Modbus protocol already know, we need to compile an application note that will answer most of the common and some not so common questions customers have when implementing Modbus.

I would like to know of the questions you would like answered that are not discussed in the datalogger manuals. I look forward to your suggestions.

Regards,

He encontrado este comentario, y como usuaria poco experimentada en el tema Modbus y tambien trabajando con datalogger principalmente, me gustaria que ampliaran las instruciones de conexion desde crbasic a un ejemplo de software que se encuentre en el mercado, por ejemplo en https://s.campbellsci.com/documents/us/technical-papers/dataloggers-as-modbus-slave-devices.pdf encontramos en la pagina 5 un ejemplo de comunicacion Modbus de un cr1000 con Modbus poll, pero no sugiere instrucciones para la comunicacion, por lo tanto seria bueno que cuando se den este tipo de emplos se pudiera agregar mas instrucciones especificas, para quienes somos nuevos en el tema. gracias por leerme.
