Analog Output Option
The analog output option board (Figure 2-107) is installed in position 3 (Figure 2-94) on the main
board. It provides either a 0-10 VDC or a 4-20mA (but not both at the same time) analog signal
proportional to the weight applied to the scale.
2.4.6.5.
ControlNet PLC Option
The ControlNet PLC option board (Figure 2-108) is installed in position 3 (Figure 2-94) on the
main board.
The ControlNet option 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 2-108 are not used.
