18 4 Working Principle 4.1 Modbus Master The data conversion between Modbus and PROFIBUS of GT200-DP-RS is established by mapping. GT200-DP-RS has two data buffers, one is PROFIBUS network input buffer; the other is PROFIBUS network output buffer. Command ID 1, 2, 3 and 4 of Modbus puts the data read from Modbus slave station into network input buffer for reading by PROFIBUS network; Command ID 5, 6, 15 and 16 of Modbus write the data from network output buffer into Modbus slave station. Input buffer Output buffer Modbus Device 1 Modbus Device 3 Modbus Device 2 Modbus Device 4 Support 01H, 02H, 03H, 04H, 05H, 06H, 0FH, 10H function codes, when using DP Hardware Configuration, users can configure 48 Modbus commands Module. When using Software Configuration, users can configure at most 100 Modbus commands in the software SST-MPG-CFG. 4.2 Modbus Slave The data conversion between Modbus of GT200-DP-RS Modbus Slave and PROFIBUS is established by mapping relation. GT200-DP-RS has two data buffers, one is PROFIBUS network input buffer, and the other is PROFIBUS network output buffer. Network input and output buffers are relative to PROFIBUS. Modbus write-register commands write data 18

19 into network input buffer for PROFIBUS network reading. Modbus read-register commands data from network output buffer, and transmit to Modbus master device through response messages. PROFIBUS PROFIBUS Input buffer Output buffer Modbus write commands: 06H 4xxxx (40001) 3xxxx (30001) Modbus read and 10H (40002) (30002) commands: 04H Modbus read commands: 03H (40003) (30003) Modbus write commands: 05H 0xxxx (00001) 1xxxx (10001) Modbus read and 0FH (00002) (10002) commands: 02H Modbus read commands: 01H (00003) (10003) Support Modbus register address area 3 (3xxxx), area 4 (4xxxx), area 0 (0xxxx) and area 1 (1xxxx); and area 3 supports 04H function code; area 4 supports 03H, 06H, and 10H function codes; area 0 supports 01H, 05H, and 0FH function codes; 1 area supports 02H function code. PROFIBUS DP input buffer being relative to Modbus side is Modbus master output, mapping to Modbus holding registers 4xxxx (10H and 06H commands are used to write data, 03H command is used to read back data) and loops 0xxxx (0FH and 05H commands are used to write data, 01H command is used to read back data).
