TIM 4R / TIM 4RD
Local communication in the rack of an S7-300
• Over backplane bus with the S7-300-CPU
• Over backplane bus with other TIMs in the
rack
• Over MPI port of the S7-300-CPU
2)
with other
CPUs, TIMs, and/or PCs
• Possible using TD7onCPU
1)
• Possible
• Possible over TD7onCPU (for S7-300 and
S7-400) and S7 communication (for
ST7cc/ST7sc and TIMs)
Local communication in standalone mode
• Over MPI port of the CPU with CPUs, other
TIMs and/or PCs
• Possible over TD7onCPU (for S7-300 and
S7-400) and S7 communication (for
ST7cc/ST7sc and TIMs)
Work memory required on the S7 CPU At least 20 KB; actual requirements depend on
the amounts of data and range of functions
Message memory on TIM
• Number of messages
• Buffered
• Approx. 10,000 messages
• no
