Technical Specification:

1. Protocol conversion between PROFINET and Modbus.

2. Supports standard PROFINET I/O RT protocol;

3. PROFINET: supports up to 32 slots, input/output data buffer is up to 384 bytes (the length uses can use is limited to specific PLC and PDU size of communication module), the length of input/output bytes can be set by STEP7;

4. The protocol type serial ports support: Modbus master, Modbus slave, simple-defined protocol;

5. With 2 serial ports, serial I support RS-232,serial II support RS-485,Two serial ports can be used as communication ports, and they can communicate at the same time. 

6. Serial port parameters:

    Operation mode: half duplex;

    Baud rate: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200bps;

    Data bits:7, 8;

    Check bit: none, odd, even, mark and space optional;

    Stop bits: 1 bit, 2 bits.

7. Modbus master:

    Function code: 01H, 02H, 03H, 04H, 05H, 06H, 0FH and 10H;

    Format: RTU and ASCII;

    Function: Cycle output, forbidden output and change of value output of write command;

    Each master can configure up to 48 Modbus commands;

8. Modbus slave:

    Function code: 03H, 04H, 06H and 10H;
