26 System Manual, 07/2009, C79000-G8976-C178-07
TIM 4R-IE
Local communication
• Over Ethernet interface with CPUs, PCs and
other TIMs
When used in an S7-300 controller
• 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
1)
with other
CPUs, TIMs, and/or PCs
• Possible over TD7onCPU (for S7-400) and S7
communication (for ST7cc/ST7sc
and TIMs)
• Possible over TD7onCPU and
TD7onTIM
• Possible
• Possible over TD7onCPU (for S7-300 and
S7-400) and S7 communication (for
ST7cc/ST7sc and TIMs)
Local communication
• Over backplane bus with local CPU
• Over backplane bus with other
local TIMs
• Over MPI port of the local CPU with other
CPUs and/or PCs
• Possible over TD7onCPU
1)
and
TD7onTIM
• Possible
• Possible using TD7onCPU
Work memory required on the S7 CPU
• SINAUT TD7 on CPU (TD7onCPU)
• SINAUT TD7 on TIM (TD7onTIM)
