MODBUS to PROFIBUS gateway technical indicators:

(1) The gateway has two functions on the MODBUS side: the gateway of the MM function is a slave station on the PROFIBUS-DP side, and the MODBUS master station on the MODBUS side; the gateway of the MS function is a slave station on the PROFIBUS-DP side, The MODBUS side is a MODBUS slave station; the interface realizes data transparent communication between PROFIBUS and MODBUS through data mapping of the PROFIBUS communication data area and the MODBUS data area;

(2) MODBUS 01H, 02H, 03H, 04H, 05H, 06H, 0FH, 10H functions are supported regardless of whether the MODBUS master station or the slave station is used;

(3) PROFIBUS-DP protocol, in accordance with; JB/T 10308.3-2001: Measurement and control of digital data communication - Fieldbus for industrial control systems - Part 3: PROFIBUS specification;

(4) Standard PROFIBUS-DP drive interface, baud rate adaptive, maximum baud rate 12M;

(5) The number of inputs/outputs on the PROFIBUS side can be freely set by the user in the following three ranges:

1Input Bytes + Output Bytes ≤ 232 Bytes;

2 Max Input Bytes ≤ 224 Bytes;

3 Max Output Bytes ≤ 224 Bytes.

(6) Standard RS-232/485 interface, half-duplex, baud rate is optional at 2400, 4800, 9600, 19.2K, 38.4K, 57.6K; check digits (even, odd, none) are optional;
