Communication Between the CPU and the IP 266 IP 266
7.2 Input Frame (IP 266 PLC CPU)
The allocation of the bytes in the input frame depends on the slot used for the
IP 266 in the programmable controller. Like Table 7-2 for the output frame,
Table 7-7 shows the allocation of the input bytes (IB) to the current slot numbers.
