Hi all,
I have a compactlogix and a 1769-SDN scanner connected to ABB robots with devicenet.
After mapping etc I have 64bits Input and 64 bits Output per Robot I think this is the robot limitattion ie 8bytesIn and 8 bytes out.
I need to send some bits no problem. I used group input/output on the robot to send bytes and words. Problem is on the PLC side DINT/Dout=32bit. I used bits 0-3 for one mould ID (no more than 7)In/Out and bits 16-31 for counts ie a word(65535)In/Out.
What is the easiest way to tell RSlogix to group certain bits together to form a byte or word input and output.
Inother words bits 0-3 will be word 1 and bits 16-31 will be word 2. I need to get this IN and send it Out.
The robot is all done and was a breeze. I know the PLC can do it. Do I,do it the old fashion way and move each specific bit into a specific place in a new word or is there a neat way. Help very much appreciated.
