The 1756-L63 is a Programmable Automation Controller (PAC) from Allen-Bradley. This controller is part of the earlier Logix controller version which is specifically part of the 5560 product series. This controller comes with an RS232 Serial communication interface as the primary communication port, however, this controller supports other communication protocols such as EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, SynchLink and other 3rd party communication protols by installing Allen-Bradley communication adapters and encompass partner modules.
