Micrologix 1200 communication

What communication option do I have with Micrologix 1200 (to connect it to a network)? I will talk to my customer tomorrow about the controller, not sure if the customer has a set standard already but I would like to discuss the options..

Are there communications modules available that tag on to the PLC? Just like a siemens S7-200 internet or profibus module.. I am fairly new to Allen Bradley.. Any help would be greatly appreciated..
