2.7.- CVM-NET COMMUNICATIONS

One or several CVM-NET analyzers can be connected to a computer or PLC. This system

makes it possible to centralise the data in a single record point, in addition to the normal

operation of each of them (PowerStudio® System). The CVM-NET has an RS-485 serial

communication output. If more than one analyzer is connected to a serial communication bus

(RS-485), each analyzer must be assigned a peripheral number or address (from 01 to 255),

with a maximum of 32 units per communication bus, so that the central computer sends the

queries from the various records measured or calculated to these addresses.

The CVM-NET power analyzer communicates using the MODBUS RTU© protocol (Pulling

Question / Answer).
