Usage method and principle
Hardware installation: Allen Bradley 1756-L8SP installed through the 1756 backplane, supporting 4, 7, 10, 13 or 17 slot racks. Dual controller modules must be installed for redundant configuration, and data synchronization is achieved through the 1756-SRM synchronization module.
Power and communication connection: Allen Bradley 1756-L8SP supports redundant power supply and requires a 24V DC power supply (±10% fluctuation range). The Ethernet port supports ring or star topology and can be connected through Studio 5000 configures IP address and network parameters.
Programming and configuration: Use Studio 5000 Logix Designer software for programming, supporting ladder logic, structured text (ST) and function block (FBD) languages. Supports online editing and downloading, and can update programs without stopping.
