I am trying to read a tag from ControlLogix 5550 which has a size greater than the buffer size of the PLC(511 bytes). Im using the CIP protocol for doing the read. Is there any method by which i can read the tag in one single instruction ? If i need to read the tag using multiple reads, can we do the same via CIP ? As far as i know, we can read a particular element of an array tag using CIP, but i did not find any documentation that says that i can read a range of elements in an array tag using a single read command. I certainly appreciate any pointers in this regard.
