Control system SIMATIC TDC - Modules

SIMATIC TDC is a modular multi-processor system comprised of one or more racks. The racks are equipped with CPUs, I/O modules and communication modules

Components of TDC
Rack UR5213		The electromagnetically shielded 19" rack UR5213 allows scalable expansion of hardware with large reserves of power. It is suitable for wall and cubicle mounting and has an integral power supply with active cooling and internal monitoring. The performance can be increased by plugging in up to 20 CPUs or by connecting up to 44 racks together.
Central processing CPU551		The central processing unit CPU551 is suitable for open and closed-loop control tasks with very high computing requirements. The CPU ensures strictly cyclic processing with adjustable scanning intervals
I/O module SM500		The SM500 I/O module offers numerous options for connecting the digital and analog I/O. In addition, incremental position encoders and absolute encoders can be connected.
Communication modules CP50M0, CP51M1		The communications modules CP50M0 and CP51M1 provide high-performance communication for - Commissioning - Process control - HMI They handle the powerful protocols - MPI - PROFIBUS DP - Fast Ethernet with TCP/IP and/or UDP
Global Data Memory GDM		By means of a Global Data Memory (GDM), a number of racks with CP52x0 can communicate with one another for an almost unlimited expansion of the computing power. Up to 44 racks can be networked by means of fiber optic cables and a shared memory. Apart from the communication between several racks, the GDM also allows synchronization (scanning time, clock time) and alarm functions. The update time is set at < 1 ms.
