6.2 Extension Backboard
The extension backboard can only install IO module. E.g. LK117 for example, as shown in Figure 6-6,
Slot 1 is the communication module slot, installed with a LK-dedicated communication module. Slots
2~11 are I/O module slot, installed with an I/O module of the DP bus interface. Each terminal block
corresponds to an I/O module, directly connecting to the field signal via an I/O cable.
