  • Page 20: Modbus

    3 Modbus 3.1 Introduction The L-STAT operates as a Modbus slave in Modbus RTU mode. The default baudrate is set to 57600, the default parity is set to ‘none’ and the default address is set to 1. The communication with a Modbus master device will work with Modbus function code 0x03 (Read Holding Registers).
