The MPI ports of the S7-300-CPU can be used with the following CPU types:
All variants of the CPU 312, CPU 312C, CPU 314 and CPU 314C;
the CPU 315-2 DP and the CPU 315F-2 DP
1.3.8 The TIM 4 variants
There are two variants of the TIM 4, the TIM 4R and TIM 4RD.
They do not have an integrated modem but have two combined RS-232/RS-485 ports to
connect to a WAN. The TIM 4RD has a DCF77 radio clock receiver.
These communications processors share the following properties:
● S7-300 housing, double width
● Has an MPI interface
● Compact unit that can be used in a wide variety of situations:
– as a communications processor (CP) in an S7-300
– as a standalone device combined with one or more S7-400s, S7-300s or control
center PCs (SINAUT ST7cc or ST7sc) over their MPI interface
