Introduction to the SINAUT ST7 system
2.3 SINAUT TIM communication modules
● MPI interface (9-pin SUB D socket) for connecting the TIM as a standalone device to one
● 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 4
● The DCF77 adapter cable supplied with the TIM 4 types with radio clock receiver has a
● Simple installation; the TIM 4 is mounted on an S7-300 rail. If it is installed in an S7-300
● The TIM 4 types can operate without fans. No backup battery or memory module is
