I have chosen instance 9 and 12. They have 9 and 11 bytes respectively. I am mapping into a compactlogix scanner. I have broken it up into 4 bytes in word 0, 3 bytes in word 1 and 4 bytes in word 2, these are all dint words. My question is there any read only I have to account for. RSNetworx Ver 5.11 allowed me to do this.

Any help would be appreciated....

My documentation shows instance 9 has 11 bytes and 12 has 9 bytes. I understand how you mapped it but not your question. Could you be more specific?
