ControlNet Interface

The ControlNet PLC Module (Figure 2-59) connects to the ControlNet network via a tap and drop
cable from the original trunk cable. The option supports one connection or two (for redundancy).
Channel A is the normal connection and Channel B (redundant with Channel A) can be used if
ControlNet detects no signal on Channel A. Note that the module's address is set in software, and
the MAC ID switches indicated in Figure 2-59 are not used.
ControlNet network connections are made by using taps and drop cables from the main trunk line.
Figure 2-60 shows examples of two different ControlNet tap and drop cables. Note that the
connector may be straight or right-angled, as seen here. This drop cable is not supplied by
METTLER TOLEDO.
