ProWorx 32 addressing

So I'm a bit new to programming and a little stumped. I'm editing an already built program that has tags already addressed to I/O's... Here's where I'm stuck. Some of the I/O's have like port numbers I guess you could say (I don't know the technical term) but it looks like this: 40021:4 etc. What do I need to do to program that specific I/O and not the broad 40021. Thanks!

Not sure I completely understand your question.

40021 is a 16 bit integer. 40021:4 is the address of fifth bit in that integer.

40021:0 (bit 0)
40021:1 (bit 1)
40021:2 (bit 3)
40021:3 (bit 4)
40021:4 (bit 5)
and so on...

Use the SENS, MBIT, RBIT, and SBIT instructions to read, conditionally modify, reset, or set, an individual bit in a 4:XXXXX word.


0:XXXXX addresses are output bit addresses for discrete output cards.
1:XXXXX addresses are input bit addresses for discrete input cards.
3:XXXXX addresses are input word addresses for analog input cards.
4:XXXXX addresses are internal word addresses and when mapped by the traffic cop to an analog output card can be analog output words.

Download the Modicon Library Block User manuals - google knows where they are.

My condolences to you about you being stuck using that rubbish known as Proworx32.

Using the example you gave...
How would I tell 40021:2 to do something without telling the other 15 bits to do something? If that makes sense.
Example: I am using a BLKM to move 10001 to 40021 ...How to I tell the rest of the bits in the address what to do?

So I can use SENS, MBIT, RBIT and SBIT to modify individual bit assignments?

Yes, that is how you read or change the state of an individual bit.

Yes thank you, I'll let you know how it turns out. Appreciate the help from all!!

Careful. Address 10001 is a single bit. Are you moving 16 consecutive inputs to 40021? Test this. I think you have to use MBIT and a pointer to stuff 10001 through 10016 into one 4:xxxxx word. I don't think a block move works in this case, I think you'll end up one bit in each word 40021 through 40037.

Disclaimer, I don't touch Modicon 984s anymore so I'm going from memory, someone correct me if I'm remembering wrong.

Here's a better example:
40270 needs to get mapped to 40021:15
