What is the most efficient way to link I/O in Control Logix?
The reason for this post is that on a system we recently built using Ethernet IP, the robot was set up as a slave to the controller and a master to an I/O block. Due to an error in the robot software, it is not able to be a master and a slave at the same time, without com errors happening on occasion.
To fix this, the controller is now the master of the I/O block and passing I/O on to the robot witch is now only set up as a slave. The pass on was done with a "MOV" statement, and is only done once each scan.
Is there a way to link an input word to an output word, in the background, so that there is not done during the scan and will have no "scan" delay.
