The Siemens SIMATIC T1505 Model 545 (more commonly known as the TI545 within the SIMATIC 505 series) is a legacy programmable logic controller (PLC) system. Originally a Texas Instruments (TI) product, it became part of the Siemens automation family when Siemens acquired TI's PLC division.
Key Details
Product Status: The SIMATIC TI505 product family has been discontinued. Siemens announced its end-of-life, with the product discontinuation status becoming effective on January 4, 2016, and the end of all technical and service support in subsequent years.
Function: It is used for industrial automation, controlling machinery and plant processes. The system uses various modules, including CPU processors (e.g., the 545-1101, 545-1104 models), input/output (I/O) modules, and power supplies, which fit into a rack/chassis.
Legacy Support: Because the system is obsolete, "new" parts are no longer available through official Siemens channels. Users generally rely on surplus markets (like eBay), third-party repair specialists (like EIC Repair), and specialized support companies for spare parts and repairs.
Software & Documentation: Programming for the system was often done using software like TISOFT or PLC WorkShop for Siemens 505. System manuals and technical descriptions are available for reference through the Siemens support site.
