AB PLC talks with EtherNet\IP on Ethernet Networks..
PLC5, MLX Series PLC uses DF1 Protocol for Serial RS232 Communication.
Lower End AB PLC's/Net-ENI Modules uses DF1 Protocol encapsulated with EtherNet\IP CIP Services for cummunication.
Latest AB PLCs uses EtherNet\IP(Pure CIP Services) for communication. Check, http:\\www.odva.org for more details into these protocols. With NI-OPC Servers, Lower End AB PLCs such as MLX Series, PLC5 Series can be integrated with LabVIEW. however., NI OPC Server doesnot supports Control Logix and Compact Logix PLCs.
If you are looking for some low cost solution to integrate All kind of AB PLCs with LabVIEW Software, Check this link, http://forums.lavag.org/Industrial-EtherNet-EtherNet-IP-t9041.html&p=35563#entry35563
