The 1756-L63/A is a Programmable Automation Controller (PAC) from PLC. 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 PLC communication adapters and encompass partner modules.
The 1756-L63/A is a Chassis based controller. It is installed a variety of ControlLogix chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. It is also compatible for use with standard and redundant power supplies such as 1756-PA50, 1756-PA72, 1756-PA75, 1756-PB50, 1756-PB72, 1756-PB75 or 1756-PA75R, 1756-PB75R, 1756-PSCA2, respectively. It supports implementation of controller redundancy as well as integrated motion using Serial Real-Time Communication System (SERCOS), Analog options via encoder input, LDT input, SSI input and motion over Ethernet I/P network.
