CVM-1D communication
One or several -CVM-1D analyzers can be connected to a controller or PLC. Using this system you can operate each of the analyzers as usual as well as centralize the data in a single
location. CVM-1D incorporates an RS-485 type communications output. If more than one analyzer is connected to an RS-485 serial bus, each of them must be assigned a peripheral
number or address so that the communications master can send the queries regarding the different measured or calculated records to those addresses.the RS-485 connection is carried out
via the shielded twisted pair communication cable, with a minimum of two wires and with a maximum distance between the communications master and the last unit of 1,200 metros. The
device uses an RS-485 communications line that can support a maximum of 32 units in series per bus.
The CVM-1D type power analyzer communicates via a Modbus/RTU© protocol (Question / answer polling).
