I have 2 LOGO 230 RCEo, from the first one I control the lights and from the second one I control shutter movement. LWE with the app is uploaded to the SD card on the first PLC which controls the lights. I can control the lights, but when I'm trying to control shutters i have a problem - none of the relays doesn't respond to the command. To communicate between PLC I have created Network project and connected two PLC with flags (attachment 1.png). Everything works fine, except shutters which don't work on the app. For shutter control on LWE l have used Push button, mouse mode HOLD and the block type M with corresponding flag number.
