Explanation of the Functions
Describes an outline of the communication functions of the MV.
Modbus slave
•
By using the Modbus protocol, measured/computed data written to the MV’s input
register can be read by the PC and communication input data can be written/read
from the MV’s hold register.
•
For the Modbus function codes that are supported by the MV, see section 4.1.
•
This function can be used only when communicating via the serial interface (option).
•
For the settings required to use the functions, see section 4.4.

Serial communication
MV
Modbus master
•
Loads the measured data of other instruments using the Modbus protocol. The
loaded data can be handled as communication input data of the computation function
(/M1 option) on the computation channel.
•
Function for writing data to other instruments is not supported.
•
For details on the Modbus function codes that are supported, see section 4.1.
•
This function can be used only when communicating via the serial interface (option).
•
For the settings required in using this function, see section 4.4 and 4.5.
