Basic FIOD Operations | |
Function The FIOD series products add digital capability to PLC / SCADA. Models are available that offer upto 16 digital inputs and upto 16 digital outputs. The digital inputs and outputs are isolated from the host device. FIOD has one RS 485 (2 Wire) communication port to connect to host device. Communication settings like baud rate, parity and station ID can be set by DIP Switch. Communication with Host FIOD module supports Modbus RTU (Slave) Protocol. The communication can be done with Host through 2 wire RS 485 Network. In case of communication failure with Host, all the outputs are switched OFF. Modbus Registers Mapping There are 128 Modbus registers supported in FIOD. Out of which, 64 are input registers (1 to 64) which are mapped to input coils 1 to 1024. FIOD has 64 output registers (65 to 128) which are mapped to output coils 1025 to 2048. First 16 coils from 1 to 16 are assigned for FIOD inputs (1 to 16). Coils from 1025 to 1040 are assigned for FIOD outputs (1 to 16). Modbus Mapping of Registers and Coils are mentioned below : Sr.    Register         Range            Modbus               Modbus No.   /Coil                                      Mapping              Tag Length 1.    Input Register     1-64               40001-40064        2 -bytes |
