msg block

I'm having problems with a msg block. I'm trying to send data from a control logix processor to a plc5. The error in the msg block configuration menu states that the configuration data size is to short. error code 16#0013. I have the number of elements at 1. I have tried 4,16,32. They all come back with the same result. In the help file it states the number of elements is the number of bytes in the the source. The source is a real number and i'm trying to write it to a f:## in the plc 5. Any ideas to how many elements i need to put in? Or what could be causing this error?

Are you connecting over EtherNet/IP, DF1, DH+, or ControlNet ?

The Length value in the MSG instruction in the ControlLogix should be the number of destination elements. If you are sending just one REAL tag to one Fx:y element, then your number of elements is 1.

If your source element is part of an array tag, be sure to specify the array element "floatdata[x]" instead of just the array tag "floatdata"
