Hi, I have a problem with my communication, i have a PLC M340 with a communication module NOE0100. I used commands like Read_Var and Write_Var to read and write in registers. The communication works well, but my only problem is when i put the power off and then i restart the system again, the communication is not working, and i have to push the reset button wich is situated in the front of the NOE0100 communication module, then i get my communication like before. I used a timout parameter and i used a cold-start procedure (as i know) but any of them are not working. Any one can give me a simple solution or perhaps the main problem is specifically the card is not working well (the hardware)... Thanks

I can't read and write the same device (in the same line in the Tab), i must split the tasks of read and write into three lines with the same IP address I use I/O scaning with an ADAM6050 to: Read Digital inputs and Read/Write digital outputs. The device has an IP address: 192.168.1.97. Write task of digital outputs : Device 1: IP: 192.168.1.97 unit ID = 1, Health timeout =1500, Repetitive rate=60, RD Master Object=%MW0, RD ref slave = 0, RD length = 0, WR Master Object=%MW100, WR ref slave =302, WR length = 1 Read task of digital outputs: Device 2: IP: 192.168.1.97 unit ID = 1, Health timeout =1500, Repetitive rate=60, RD Master Object=%MW0, RD ref slave = 302, RD length = 1, WR Master Object=%MW101, WR ref slave = 0, WR length = 0 Read task of digital inputs: Device 3: IP: 192.168.1.97 unit ID = 1, Health timeout =1500, Repetitive rate=60, RD Master Object=%MW1, RD ref slave = 300, RD length = 1, WR Master Object=%MW101, WR ref slave = 0, WR length = 0 With these configuration, sometimes the read task does'nt work properly or in asynchronous mode. Thank you in advance if you have the solution of my I/O scan problem, Best regards,

Hello, i have a Modicon M340 BMX1000 processor and NOE0100 communication module. Can i use the standard functions: READ_VAR and WRITE_VAR to communicate with devices rather than I/O scan function of NOE0100, as a consequence of the problem of reading and writing with the same device with I/O scan tool. Thanks

i got the answer: i have to put a 4x address because IO scanning uses juste 4x addresses and the DO address of the ADAM is 40303 and if you put 303 it doesn't work, we have to put 302 (303-1), and of course not 40302 but specifically 302. Thanks

Hello, I want to communicate between MODICON M340 equipped with NOE0100 module and a remote IO ADAM-6050 but it does'nt work. This is my configuration of IO scanning: IP:192.168.1.97, ID:1, Health Timeout: 1500, Repetitive rate: 60, RD Master Object: %MW0, RD Slave index: 0, RD length: 0, Last Value: Hold last, WR Master Object: %MW100, WR Slave Index: 23, WR length:1 IP:192.168.1.97, ID:1, Health Timeout: 1500, Repetitive rate: 60, RD Master Object: %MW0, RD Slave index: 23, RD length: 1, Last Value: Hold last, WR Master Object: %MW101, WR Slave Index: 0, WR length:0 Slave index: 23, is the address of the register in the ADAM6050. From the user manual: 0x00017 ch0 DO R/W . I don't know if the parameter 23 (7+16) is correct or not for the IO scanning. Thanks
