Wazzzzupppppppp!
Just need to know if anyone knows of an instruction on an A1S plc that will allow me to look for the condition of a specific bit in a data register and move it to a specific destination?
Here is what I'm trying to do. I have a Hakko touch screen hooked up to an A1S Mitsubishi plc. The touch screen has a read and write area in its system memory. The read area is assigned a register and this is where the touch screen is looking for any bits that might be on. Example I used D900 for n, D901 for n+1, and D902 for n+2. Each bit in the registers are allocated to do certain things depending on which bit is turned on. For example, D900 has several functions, 16 to be exact. Bit 0 is allocated to overlap 1. Overlap is just a pop-up display area that sits on the screen currently being displayed. I can call up this overlap several ways, but the way I need to pop-up is when the Plc tells it to. No problem, I use the instruction [BSET D900 KO] in the plc, this works fine.
The problem I'm having is I want to tell the plc if the overlap is actually on. Kind of like the honor system mentioned on a previous post. The touch screen has a write area also that can be set up to reflect the status of the touch screen. Example, D910 bit 0 will turn on if I call up overlap 0 with the plc. What I need to do is use this on condition of bit 0 in D910 to let the plc know that overlap 0 is actually being shown on the screen. The problem is the other 15 bits in D910 may be on or off at times and I can't just say that if D910 = 1 the overlap must be displayed. For instance, in the same data register D910 bit 4 may be assigned to the backlighting. If backlight on the touch screen is on then bit 4 is on, now D910 = 16.
I now in the FX series there is an instruction called BON. I believe it goes something like this> [BON D910 K0 M100] This instruction will look at a specific register and a specific bit within that register and move its condition to an internal relay "M100". So, if the overlap 0 was on it would move B0 state to M100, then I can use the on condition of M100 as a good indicator that overlap 0 is on.
My problem, I cannot find an instruction to do this on the A1S plc.
Any ideas?
