However this would require the master to query my slave with certain cj1s-scu41-v1 delays e. Does anyone have an idea? That’s a little bit of nonsense to me, what is the point in it?
Register a new account. At first I thought that I’ve 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.
Posted 25 Feb edited. But is there any way to detect this 3.
Edited 25 Feb by Eradicated. Yet I have encountered another problem.
(SCUV1) Modbus Slave – area mappings – Omron –
I know I can make these both function write in the CIO area, but that’s not possible in my case. Sign in Already have an account? 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 cj1w-scy41-v1 define them to wherever you wish.

So now I would like to ask someone who had to deal with this issue in the manal So even though I have selected the W area for the coils, this function will always write to CIO area.

Posted 7 Mar edited. 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. Edited 7 Mar by Eradicated. That’s great, as due to cj1w-scu411-v1 limitations I have to use Work area in this case and that’s how the comm port has been setup.

Posted 6 Mar Posted 7 Mar 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.

And that would be enough if I wouldn’t have to use 0x0F write multiple coils function. It seems to me that someone at Omron didn’t have the time to do the work the way it should maual done. I am asking, as even the Modbus Slave protocol macro waits for defined number of characters and not relies on this delay time. Since I haven’t found workaround for the problem it seems that it is impossible to define memory area for 0x0F function.
No need – you have to define your work areas for Modbus slave in the card setup and it works easily.
