SIMATIC S7-1200 G2: CB 1241 communication board, interface: RS485, with push-in terminal block. SIMATIC S7-1200 G2 Basic Controller - The Basic Controllers are the first choice for flexibly and efficiently solving automation tasks in the lower and medium performance range. The central modules are scaled in their performance, available for different input voltages, and come with transistor or relay outputs. Safety variants are also available. In addition to the already integrated inputs and outputs, the compact CPUs can be expanded directly on the device or with various signal and communication modules to precisely meet your requirements. HMI devices can also be connected via the integrated Ethernet interface. The CPU memory can be expanded using a memory card, and the PLC is programmed with the STEP 7 Basic software in the TIA Portal. The S7-1200 G2 offers a variety of networking options through different communication standards with integrated functions like PROFINET, providing maximum flexibility in network and topology setup. The application areas for the S7-1200 are very diverse due to its compact design, ranging from simple packaging machines to heating systems and even as a subordinate system in large plants. Compact design, modular structure, and integrated I/Os help save space in the control cabinet. The project planning software STEP 7 is integrated into the TIA Portal, allowing access to a common data repository, a unified operating concept, and consistent communication services for all components of a system. This results in reduced project planning effort and faster commissioning.
