1.3.9 Design of the TIM 4 variants
The TIM 4 types have all the advantages of the SIMATIC S7-300 system design:
● Compact design; double standard width of the SM modules of the SIMATIC S7-300
● 2 WAN interfaces via 9-pin D-sub connector with a combined RS-232/RS-485 port for
connection of an external modem or other data transmission device.
● MPI interface (9-pin SUB D socket) for connecting the TIM as a standalone device to one
or more S7 CPUs or control center PCs
● 4-pin terminal block for connecting the external power supply of 24 V DC
● LEDs on the front panel with SF, TXD, RXD, and MPI/K indicators and, on the TIM 4RD
with radio clock receiver, DCF77 indicator (the TIM-BUS LED is unassigned on the TIM 4
types).
● The DCF77 adapter cable supplied with the TIM 4RD has a BNC connector for
connecting the antenna cable.
● Simple installation; the TIM 4 is mounted on an S7-300 rail. If it is installed in an S7-300
as a CP, it is connected to adjacent modules by means of the bus module connectors. As
a standalone device, it is connected to the S7 CPU(s) or control center PC(s) via its MPI
interface.
● The TIM 4 types can operate without fans. No backup battery or memory module is
required.
