Go To Topic Listing Omron. Does anyone have an idea how to manage 3.

Since I haven’t found workaround for the problem it seems that it is impossible to define memory area for 0x0F function.

However this would require the master to query my slave with certain time delays cj11w-scu41-v1. No need – you have to define your work areas for Modbus slave in the card setup and it works easily.


Posted 8 Mar And since Cj1w-su41-v1 cannot use CIO area for the coils and have to use write multiple coils during communication, I have to implement my own protocol. At first I thought that Ccj1w-scu41-v1 found a bug, until I came across a description on the page of above-mentioned manual, i.

In general I could continuously check the receive buffer every cycle and verify if it doesn’t change in consecutive cycles and on that basis decide whether a transmission is over. Or define time value in [ms] for the same purpose to check if transmission is over.

That’s a little bit of nonsense to me, what is the point in it? Edited 7 Mar by Eradicated. I cannot understand why you do not want to use CIO – it is a huge mud map and I would be surprised if you ever use it up. Sign In Sign Up. So now I would like to ask someone who had to deal with this issue in the past: Posted 7 Mar edited.

Posted 7 Mar I know I can make these both function write in the CIO area, but that’s not possible in my case. Edited 25 Feb by Eradicated. Share this post Link to post Share on other sites. But is there any way to detect this 3.

So this is doable. Go to IO Table and Unit Setup – open the serial card – select which areas you wish to use for cils area, input registers and holding registers – you can define them to wherever you wish. Posted 6 Mar It seems to me that someone at Omron didn’t have the time to do the work the way it should be done. That’s right, I can select the work area for the Modbus coils area: And that would be enough if I wouldn’t have to use 0x0F write multiple coils function.

Now I would like to focus on coils in Modbus, as I’ve encountered a little problem here.
