5.9 Table of Modbus Variables
Each device connected to the same RS485 bus must have its own address, otherwise there will be conflicts in
transmission/reception that prevent serial communication.
The write registers are password-protected. By entering the password in the appropriate
register, authorization to write the variables will be provided for 15 minutes. There is a specific variable that
indicates whether or not the device is currently locked.
