Posted 8 Mar Go To Topic Listing Omron. I know I can make these both function write in the CIO area, but that’s not possible in my case. Or define time value in [ms] for the same purpose to check if transmission is over. So even though I have selected the W area for the coils, this function will always write to CIO area. I am asking, as even the Modbus Slave protocol macro waits for defined number of characters and not relies on this delay time.

Does anyone have an idea how to manage 3. Create an account or sign in to comment You need to be a member in order to leave a comment Create an account Sign up for a new account in our community. At first I thought that I’ve found a bug, until I came across a description on the page of above-mentioned manual, i.

Register a new account. I would be grateful for any advice. And since I cannot use CIO area for the coils and have to use write multiple coils during communication, I have to implement my own protocol. Share this post Link to post Share on other sites.

In general I could continuously check the receive buffer every cycle and verify if it doesn’t change in consecutive cycles and cj1-scu41-v1 that basis decide whether a transmission is over. But is there any way to detect this 3. So this is doable. That’s right, I can select the work area for the Modbus coils area: Cj11w-scu41-v1 in Already have an account?

And that would be enough if I wouldn’t have to use 0x0F write multiple coils function. Posted 6 Mar You need to be a member in order to leave a comment.

So now I would like to ask someone who had to deal with this issue in the past: Edited 7 Mar by Eradicated. Yet I have encountered another problem. Sign In Sign Up. Edited 25 Feb by Eradicated. I cannot understand why you do not want to manuql CIO – it is a huge mud map and I would be surprised if you ever use it up.

Posted 25 Feb edited. Allocated cj1w-xcu41-v1 is in the CIO Area fixed. No need – you have to define your work areas for Modbus slave in the card setup and it works easily.

Go to IO Table and Unit Setup – open the serial card – select which areas you wish to use for cils mabual, input registers and holding registers – you can define them to wherever you wish. Posted 7 Mar That’s a little bit of nonsense to me, what is the point in it? Does anyone have an idea?

Though, according to the manual WE, page when it comes to write multiple coils Modbus function the area is fixed i. Now I would like to focus on coils in Modbus, as I’ve encountered a little problem here. Manuall I haven’t found workaround for the problem it seems that it is impossible to define memory area for 0x0F function.

It seems to me that someone at Omron didn’t have the time to do the work the way it should be done. However this would require the master to query my slave with certain time delays e. That’s great, as due to some limitations Manua have to use Work area in this case and that’s how the cj1w-dcu41-v1 port has been setup.
