4.4 System Operation with LFC-6CIO-PC
4.4.1 Standard Operation with PLC Interface
Table 11 for the analog outputs and Table 12 for the digital in/outputs shows the standard configuration of
the electrical interface (PLC). For other configurations the Levitronix
®
Service Software has to be used (see
reference on title page of this manual). The hardware configuration is the same as for the PLC of the LFC-
1C-PC . Therefore, the same typical setup applies as described in Section 4.2.2 .
4.4.2 Operation with RS485
Standard operation with LFC-6CIO-PC is done with the RS485 interface. The according MODBUS protocol
can be requested at Levitronix

.
4.4.3 Standalone Operation with Display
The LFC-6CIO-PC can be used as standalone device, where the flow values can be read on the display. The
channel to be read can be chosen with the channel selection potentiometer on the display (see Figure 14 ).
The 6-channel converter LFC-6CIO-PC displays basically the same messages as the single channel
converter LFC-1C-PC (see Section 4.2.1 ).
Additionally, LFC-6CIO-PC shows on the display on the right side six LEDs (see Figure 14 ). These LEDs
indicate which channel has measurement error active (when channel selection is set to a specific channel 1-
6) or indicates, which flow is shown in display (when channel selection is set to 0).
