TI 505/555

Siemens TI 505 / TI 555 (previously known as Texas Instruments) systems are rack based, medium to large size PLC Systems. Most of the TI 505 applications are found in process industries, but these systems were also used in other applications. TI 505 was originally developed by Texas Instrumentation and after the acquisition, continued by Siemens.
3rd party units have been developed for the TI platform by the company called CTI.
