TIM 44 / TIM 44D
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
