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.

Rubik Hub | Cj1w scu41 v1 manual transmission – Rubik Hub

That’s a little bit of nonsense to me, what is the point in it? I know I can make these both function write in the CIO area, but that’s not possible in my case.

Does anyone have an idea how to manage 3. And that would be enough if I wouldn’t have to use 0x0F write multiple coils function. So now I would like to ask someone who had to deal with this issue in the past: Go to IO Table and Unit Manal – 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.

I cannot understand why you do not want to use CIO – it is a huge mud map and I would be surprised cj1w-suc41-v1 you ever use it up. Or define time value in [ms] for the same purpose to check if transmission is over. Go To Topic Listing Omron. Posted 25 Feb edited. So this is doable. I would be grateful for any advice. No need – you have to define your work areas for Modbus slave in the card maual and it works easily.

At first I thought that I’ve found a bug, until I came across a description on the page of above-mentioned manual, cj1wscu41-v1. It seems to me that someone at Omron didn’t have the time to do the work the way it should be done. But is there any way to detect this 3.

Edited 7 Mar by Eradicated. Since I haven’t found workaround for the problem it seems that it is impossible to define memory area for 0x0F function.

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

I am asking, as even the Modbus Slave protocol macro waits for defined number of characters and not maanual on this delay time. That’s right, I can select the work area for the Modbus coils area: Posted 6 Mar Started by Eradicated25 Feb
