- Working temperature: -30℃ to 75℃
- Working humidity: 5% - 95% non-condensing
- Protection level: IP20
- Station type: ModbusRTU slave
- Communication method: ModbusRTU
- Communication interface: RS485, 1200-115200, 8bit data bit, parity check, 1/2
- Maximum bus length: 1200m
- Configuration method: ModbusRTU protocol
Indicator Description:
- PWR: indicate power status, normally on
- SY1: system light, normally on when the program runs
- SY2: meaningless
- P0: flashing after successful communication with the master station indicates normal communication between the core board and IO module
Top Terminal Description:
- V+: positive power input
- V-: negative power input
- PE: grounding
- NC: reserved, do not connect
- A/B: RS485 communication port
Default Value after DAP Module Restart:
- RS485: 9600/N/8/1
- Slave station address: 1
- Timeout offline: 0 (how long does it take to receive instructions from the master station and determine it as offline)
- IO module number: 0
Reset Button:
- The reset button under the ModbusRTU core board is used to restore factory settings. When the user forgets the current Modbus parameters and cannot communicate or configure, long press the RST button until the SY1 light keeps flashing. The DAP module restarts and runs with default parameters.
