Arduino RS485 RTU slave communication

I need device based on Arduino Nano ([login to view URL]) and max485 module ([login to view URL]) Device should communicate on rs485 rtu as slave (19200 N 1). Communication between Nano and Max485 thrue SoftwareSerial. Registers should be then reported to Serial (communication with pc) data structure: Register address: 7000 Function: write multiple registers typedef __packed struct{ uint8_t inf1= 1; uint8_t inf2; uint16_t inf3; uint16_t inf4; uint32_t inf5; txRegistryDeviceState device_state; } xQCReport_t; typedef __packed struct { unsigned short bool1 :1, bool2 :1, bool3 :1, bool4 :1, bool5 :1, bool6 :1, bool7 :1, bool8 :1; }txRegistryDeviceState; Register address: 8000 Function: read multiple registers Data length: 4 registers (8Byt)
