I am puzzeled about something. I have a floating point value in a PLC 5/60 but when I view this value in my control logix 5000 it is a different value. My program is moving several words using the message instruction over the either-net com.
In the Logix 5000 the word is part of a large array but the address is correct. In the PLC 5 they are taking the Interger and moving it into a Floating point. N:? move F:?. The F:? is then sent by a message instruction to an Array in the Logix5000. Is there something I am missing here. I am trying to interface with a 1396 Servo Drive and this is a mess when it comes to understanding how this is working.The 1396 wants all its data transfered by R/I/O. This is the reason for the array. I am removing the PLC5 out of the system and replacing it with an Logix 5000.Looking for some feedback or location I can get info about communicating with the 1396 Servo over R/I/O with Logix 5000.
