Hi to everyone, i need to set up the modbus TCP/IP connection by the integrate PN of a CPU 315 2PN/DP. My connection are one where the CPU is SERVER and then publish datas end the other the CPU must be a client to read data fro another device (different from connection 1) I've set up the connection parameters (using wizard) and the connection like SERVER is working fine. the problem is with the second connection that if I set ip like SERVER its work, but i need like client. I've to read from modbus starting address from 45001 to 45120 and from 46001 to 46120. How I've to configure the param_db for this connection? i've set up this: [code1] OUCW_1.server_client BOOL FALSE OUCW_1.single_write BOOL FALSE OUCW_1.connect_at_startup BOOL TRUE OUCW_1.reserved BYTE B#16#0 OUCW_1.data_type_1 BYTE B#16#3 OUCW_1.db_1 WORD W#16#10 OUCW_1.start_1 WORD W#16#1389 OUCW_1.end_1 WORD W#16#1400 OUCW_1.data_type_2 BYTE B#16#3 OUCW_1.db_2 WORD W#16#10 OUCW_1.start_2 WORD W#16#1771 OUCW_1.end_2 WORD W#16#17E8 OUCW_1.data_type_3 BYTE B#16#0 OUCW_1.db_3 WORD W#16#C OUCW_1.start_3 WORD W#16#0 OUCW_1.end_3 WORD W#16#64 OUCW_1.data_type_4 BYTE B#16#0 OUCW_1.db_4 WORD W#16#D OUCW_1.start_4 WORD W#16#0 OUCW_1.end_4 WORD W#16#64 OUCW_1.data_type_5 BYTE B#16#0 [/code1] and on the OB1 I set [code2] see attach[/code2] any suggestion to how I can Setup this connection?

Hello Nickt, why do you want to access address 0 when you set start_1 to 5000? Regards, Kaulquappe |

Hello Nickt, when you want to access address 0, you must set start_1 to 0 too. Regards, Kaulquappe |
