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).
