1.5 Working Mechanism
Figure 1-9: PLC-505 working mechanism
PLC-505 has RJ45 Ethernet interface and RS232/RS485 serial
interface, so it can connect with PLCs that have Ethernet interface or
serial interface, and Ethernet and serial interfaces can be used at the
same time.
1. Usage of Ethernet interface
PLC-505 connects with PLC via Ethernet cross cable, and after
power on, it dials up into 3G/4G network (or, via cable/WIFI
network) and access Internet, then establishes connection with
cloud platform and mServer. Use browser at the host computer to
access IoT cloud platform, and monitor PLC‟s data in real time. At
the same time Virhub software is run at the host computer and
connects to mServer as well. Then with Virhub functionality PLC and
the host computer are in the same virtual LAN, and user software at
the host computer can then access PLC, to download or update
program.
PLC-505 has two RJ45 interfaces, and can be WIFI AP. So it allows
multiple PLCs (or other devices) that have Ethernet interface to
connect with it. And with PLC-505‟s virtual channels, one PLC-505
can serve at most nine PLCs to perform remote data acquisition and
