TIM 4R / 4RD

The TIM 4R is the predecessor of the TIM 4R-IE and also has 2 combined RS232/RS485 interfaces. Instead of RJ45 ports, the TIM has an MPI terminal through which it can be connected to a PC in the control center or to a CPU in an S7-400 station. The TIM is also available with an optional DCF77 radio clock receiver (TIM 4RD).

The TIM handles the SINAUT communication for one or more S7-400 controllers or control center PCs (SINAUT ST7cc or ST7sc) as a stand-alone device (stand-alone operation without S7-300 CPU); the connection in this case is via the MPI interface of the TIM.
As a communications processor (CP) in an S7-300 or C7.

Flexible connection options

It has two combined RS232/RS485 interfaces for connection to standard WANs such as dedicated line, wireless or dial-up network. The two transmission paths can be different and operated independently or in redundant combination.

Reliable storage of important data

Storage of data message frames (approx. 10,000) including time stamp on TIM if the communication path is faulty or a partner has failed, and to reduce connection costs for the dial-up network.

Accurate time source

The TIM 4RD comes with an additional installed DCF77 radio clock receiver

For supplying all SINAUT nodes (PCs, TIMs, CPUs) connected locally over MPI with the date/time-of-day, and to synchronize all SINAUT nodes in the WAN.
For the precise control of data traffic in a wireless network with time slot procedure.
