Modbus settings on TWIDOSUITE

[trespaser5 0]

Hi, I'm trying to set up a TWIDO PLC with a NQ5 HMI, I have set up the HMI with a TWIDO protocol and I can get connection however the data comes up as ???? and it won't change the value in the register. I also can't get a configuration window up in Twidosuite. What am I doing wrong ? I'm very tired.

What type of communication are you using? Using the programming port? Twido do not support beeing asked for an adress not in use. And HMI's block their telegrams. So it is smart to use a word with high numer in program. Then all words up to this adress is defined. You can write %MW200:=0 some place in your program. In describe in Twidosuit you configure the modbusport.

Hi, Sorry my message didn't make sense, It was very late. I hadn't set up the master slave on the 'describe' page of twido suite but I have now and have managed to write/read some addresses,so hopefully we'll be ok. Thanks for the reply
