CONNECTING FACTORY IO WITH CODESYS MODBUS

Below are the variables I used when connecting Factory IO with CODESYS
//STATION INPUTS
I0 AT %IX0.0:BOOL; // START
I1 AT %IX0.1:BOOL; // STOP
I2 AT %IX0.2:BOOL; // POINT A

// STATION OUTPUTS
Q0 AT %QX0.0:BOOL; // CB1 FORWARD

The bit toggling like that is a good indication that you have a register enabled, check your driver configuration and make sure registers is set to 0. Is toggling because the register overrides the bit on each scan.

Great video I learned a lot. As for the flickering 'STOP' button problem, I found out just by switching the address to for example 'IX0.7' fix the problem. Don't really know the details, but sometimes it happened
