Re: How to save a component

Hi Stefan.

I have been looking at those development kits also.
Are you using the humidity - what's the accuracy like ?

Got a idea lurking for a data logger for our binder climate chamber

Re: Modbus Master Speed

Hi Seokgi, I am not around much next week. you said in your original post "HMI : Serial_3 : Modbus RTU via RS-232(1ea)(Slave)" and that it does not work on the HMI. are you using RS232 for this ? - i have no experience using modbus over RS232, as far as i have seen they are either RS484, LON or TCP/...

Re: Modbus Master Speed

Hi Seokgi, Testing every slave individually results in very slow reads. Two slaves cannot be read. If I read it with another computer program (Modbus Poll), a Time Out error occurs at the 7th Device, but the value is read.

Re: Modbus Master Speed

Hi Seokgi, i Would try the following: do an update on your flowcode, make sure that you are using the latest component's. (just in case) Have you tried the 1 second flasher, to check if your clock settings are correct ? Double check your slave addresses make sure you don't have any duplicated addres...

Re: Modbus Master Speed

Hi Seokgi,

Can you supply more detailed connection information and your flowchart so we can assist you further.
It is difficult with the information you have provided

Re: Modbus Master Speed

Hi Seokgi,

Device : Serial_1 : Modbus RTU via RS-485(7ea)(Master)
Device : Serial_2 : Modbus RTU via RS-485(5ea)(Master)
HMI : Serial_3 : Modbus RTU via RS-232(1ea)(Slave)

you cannot have 2 masters on the network, is this a typo or do you have 2 masters ?
