My client wants to recieve every data on my system through Modbus TCP for their SCADA, for that I need the addresses but I didn't define them in the first place. So I'm just trying to locate them instead of defining 500 variables again.

Thanks for the reply. I've seen that part, it only shows the hardware IO declaration. What I'm asking is if I could see the empty moemory blocks or where my unaddressed variables go in the memory.

I've read all of these in the past , sadly there's no answer to my questions in these documents.

I'm new to programming, so my question is when I define a variable like this, Variable_A: REAL; and don't add the "AT" to pick an address for it. What happens to this variable? Where can I see the assigned address after I compile the program? Is there a place where I can see the avaible addresses? Btw I'm using ABB's automation builder.

So I'm writing a basic modbus rtu program. I have defined a structure. It's like this, **TYPE DataArray : STRUCT Refperc:INT; KW:UINT; HZ:UINT; Freqperc:UINT; Volt:UINT; Speedperc:INT; END_STRUCT END_TYPE** When applying this to the modbus data input. I have defined an array which is, INSERTDATA: ARRAY [1..6] OF DataArray; To change the variables while reading ad writing I've made a slave counter and used in it. When I apply it, it looks like this, INSERTDATA[slavecounter].refperc So I want to be...

http://www.weintekusa.com/globalw/download/datasheets/Weintek%20HMI%20to%20ABB%20AC500-eCO-CPU%20PLC.pdf I've done everything in this guide. But I just can't communicate with the PLC. Also my HMI doesn't show up when I IP search on my PLC. But I can ping it. Is there anyone experienced with these stuff that can help me?

I am a newly graduated mechatronics engineer and I've got assigned for this job, they were supposed to train me but things went south and now they're expecting me to learn this on my own. I just don't wanna lose my job so here I am asking for help. I have ABB PM-564-eth PLC and a Danfoss FC51 inverter. I'm done with connections and I've created a program using the examples. But I need some help about, -Writing correct values to read/write to VFD -Run multiple motors at the same time with different...
