есть проектик где CJ1M управляет через SCU41 инверторами V7, могу поделится.
Поделись пжл, а вот что написал техн офис омрона (я думаю в этом есть что-то новенькое)
The easy way is to use function blocks in CJ CPU. In this case the SCU31 must be in serial gateway mode. You can find info about the available function blocks for inverters in the attached file which also comes with CX-One. You won't see V1000 in the list but you can use the function blocks as if the inverter was 3G3MV series. Unfortunately, these function blocks use a lot of program memory, approx. 5 ksteps. That is why the CPU in the configuration with SCU31 was CJ1M-CPU12. After the function block you still have around 5 ksteps for your program. CPU11 is not sufficient at all.
Another way is using the SCU31 in protocol macro mode, and either creating your own protocol according to the V1000 comm. details or adapting a macro used before in other projects.
Finally, the new and easiest way: connecting inverters to NS terminal
. We have this functionality in CX-One v3.0 and NS system version 7.0. We did not have this by the time I first sent you the configuration. I think that's why I did not offer this. All you need is an NS-AL002, RS232 - RS485 converter for NS terminal. You may forget about SCU31. The only consideration would be the speed of communication, while you can connect 13 inverters to one port on SCU and 14 ports to the other, you will have to connect all of them to one port on NS.
