MODBUS TCP/IP

[ryszard 0]

I would like use connect OMRON-YASKAWA inverter CIM-F7Z41P5 PRG 4010 with communication card CM090 ( ModbusTCP/IP) with CJ11M-CPU13 with ethernet unit CJ1W-ETN21. At the beginning I want read-out registers 0001h from PC via Multiway V6.7.1 software and inverter not respond (S3 input in inverter was connect). Frame MBAP header 00A10000 Length 0006 Request 010300010001 Respond 00A1000000050103020000 Next stage : I write PLC programm using socket service respond was this same. When I want read-out some registers 0040h and next via 03h command all is OK. WHY!!! What are you thinking about inverter firmware (PRG 4010)
