Configuration manual
Basic information
AMB-8I-4O is an I/O expander operating over Modbus RTU and IEC60870-5-101 protocol. The first DIP switch is used to switch between Modbus RTU and IEC modes. If it is in position 0, then the AMB is operating in Modbus RTU mode. If it is in position 1, then it works in the IEC protocol. As the two protocols have different functions, the DIP switch is also different. In IEC mode, the last DIP switch is used to change the operating mode from balanced/unbalanced. To save the DIP switch settings in the internal memory, the SAVE button must be pressed.
Configuration
DIP switch configuration
This is DIP switch functions diagram for Modbus RTU configuration. For enable Modbus RTU protocol 1 switch should be in OFF position.
This is DIP switch function diagram for IEC protocol. For enable IEC protocol 1 switch should be in ON position.
