Re: (CODESYS) Issue on mapping DI/DO bits to exist global boolean variables for each

Hello dirk, thank you for your repry.

I see it has been specified behavior for now.
Is it going to be improved in future release?
I think bit access is still available on some other CODESYS native IO devices i.e. Modbus TCP Slave.

(CODESYS) Issue on mapping DI/DO bits to exist global boolean variables for each

Hello, I'm using RevPi Connect S & RevPi DIO module with CODESYS. I mapped DI_CH1-14 and DO_CH1-14 to existing global boolean valiables as following picture. 画像.png However, the DIO module didn't worked as I expected. (I mean that forcing the global DO variables to TRUE didn't trigger any output...

Re: Can we use CODESYS BACnet SL with RS485 interface on RevPi?

OK, I wanted some idea whether I can use MS/TP on RevPi.
Thank you anyway.

Can we use CODESYS BACnet SL with RS485 interface on RevPi?

Hello,

I am considering to import the CODESYS BACnet SL to my project.
I think BACnet IP is available with RevPi Connect, but how about BACnet MS/TP using RS485 port on the device?

Thank you for your cooperation.

Re: Cannot reset the hardware watchdog timer

Hello, u.biakoup,

>>I suspect, simultaneous reading the RevPiLED and then writing cannot be be done in current codesys library.

Are you sure about this?
If yes, is that only about RevPiLED or also about other variables?

Cannot reset the hardware watchdog timer

Hi, I am working with RevPi Connect+ and CODESYS. Recently, I activated the hardware watchdog on my device, and made a FBD to reset it. ss1.png The FBD is set to run every 100ms. I don't know why, but it doesn't work as I expected. Actually, I can make blinking the LEDs A1-A3 with similar diagrams. ...
