Hi @jagz, unfortunately it doesn't work. The power supply accepts only specified functions, i.e. FC1, FC3, FC5, FC6, FC16 as you can see on the screenshot above.

Hello community, I've got Modbus TCP App v.1.20.2 installed and trying remotely control power supply. There are multiple read/write holding registers for voltage/current reading, which works fine. But then there is single coil access, which I absolutely need to switch power supply to remote control. I was not able to read single coil with FC1 and FC5 for writing single coil doesn't even exist. I tried the communication with Modbus Master tool and everything works as expected. FC1 read succesful, FC5 write successful: What can do with that? Is there some configuration or workaround I can set or use? The FC5 single coil write command doesn't really exist on Modbus TCP app? Without that, I'm not even able to set power supply to listen remote command... Many thanks

OK, so with FW RC7 is no workaround needed anymore... There is new checkbox in Webstation URL entry dialog: Update. When you check it, you enter reqiured reconnect interval and OK. After restart, the Webstation tries periodically connect to entered URL. 👍

Is there some limit for delay value? My ctrlX Core X3 starts more than 100 seconds. The solution with delay of 30s works for me, but is useless, because after 30s is the PLC still booting. When I tried to increase delay to 90s, the Webstation waited requested time, but then displays only completely blank screen. It is not frozen, Webstation runs, I can exit from it properly. Recommended FW update to RC7 didn't help and moreover, now it is not possible to edit URL in Kiosk app... dialog shows: Invalid URL. Thanks for any hints.

OK, but then I can save the files directly to active configuration (perhaps the SD card couId be used to extend disk space). Initially, I wanted to avoid frequent file writing to active configuration (every minute, 24/7), to save system flash memory lifetime. I expected the system flash memory chips still do have limited R/W cycles. Or is this not a problem anymore and I can write to active configuration memory space without negative impact on service life?
