1.1 Brief Introduction
PLC-505 is an industrially designed product, and is especially used
with PLCs. PLC-505 provides program download and data acquisition
functionalities for PLCs that have RJ-45 Ethernet interface, or
RS232/RS485 serial interfaces. It supports PLCs from Siemens,
Mitsubishi, Omron, Panasonic, Delta, Fatek, etc. PLC-505 connects
with 4G network, and with PLC programming tools or SCADA software
to implement remote program download and data acquisition.
PLC-505 integrates functionalities of all other PLC LianWangBao
products. It not only supports all network modes from China‟s three
mobile operators, but also has two RJ-45 Ethernet interfaces, one of
which (LAN1) can be used as WAN as well, one RS232 and one RS485
serial interfaces. Ethernet interfaces and serial interfaces can be used
at the same time. It breaks through network limits, so that it not only
supports 4G network, but also 3G: TD-SCDMA/WCDMA/EVDO or 2G:
GPRS/EDGE/GSM/CDMA networks, and can automatically switch
between different networks. In case there is no 4G network or SIM
card does not support 4G, PLC-505 can automatically switch to 3G or
2G networks.
PLC-505 has WIFI functionality as well, and supports 802.11b/g/n
protocol. In theory the highest speed can be 150Mbps. Either mobile
phones, PCs or other devices that has WIFI functionality, can bind

PLC-505 User Manual

PLC-505‟s WIFI access point and share Internet access via PLC-505.
This greatly extends the number of devices that can connect with
PLC-505 at the same time.
PLC-505 can use WAN or WIFI network: in case cable network is
available, WAN (LAN1) port can be used to access cable network; and
in case WIFI is available, PLC-505 can be configured to access internet
via WIFI. 4G, WAN and WIFI are all supported by PLC-505, this greatly
facilitates customer‟s project deployment that customers do not have
to choose different devices from different suppliers because of
different network access at the spot. This can not only save
procurement cost, but also reduce maintenance effort for the projects.
GPS model can be embedded into PLC-505, to implement device
location. Set time interval of transmitting GPS location data, then after
PLC-505 connects to data center, it will transmit location data to data
center with the predefined time interval. Data center can also ask for
GPS location data at any time by sending commands. Besides, the
device connecting PLC-505 can also send AT command via
RS232/RS485 serial port to ask for location information.
PLC-505 is easy to use, and is plug-n-play without any configuration.
Together with eTung‟s eYun platform and Virhub/Vircom software, it
can be easy to integrate with PLC programming software, and there is
no extra integration effort. PLC-505 is stable and easy-to-use, thus
greatly facilitates project deployment.

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

program update.
2. Usage of serial interface
PLC-505 connects PLC with RS232 (or RS485) serial port. After power
on it dials up into 3G/4G network (or, via cable/WIFI) 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 Vircom
is run at the host computer and connects to mServer as well, then user
software at the host computer can use the virtual serial port from
Vircom to implement bi-directional communication with PLC.
PLC-505 has one RS232 ad one RS4845 serial port, and support
virtual channels on RS485 serial port. One PLC-505 can serve at most
five PLCs (or other devices) with RS485 serial port to perform remote
data acquisition and program update.

It is clear to see each configuration item in the router
configuration interface. To change some parameter, click it,
modify and then save it, then reboot the router.
To use Ethernet functionality, click “ConnBOX”-> “Ethernet”.
By default, cloud platform domain and port are
dsc.thinglinx.com and 20001, mServer domain and port are
3g.etungtech.com and 8080, and normally keep the default
settings. Then configure PLC with Ethernet interface. PLC-505
supports multiple channels; each channel can be assigned to
one PLC (or other device). PLC-505 supports at most ten
channels, and each channel has a channel ID. The channel ID is
derived from PLC-505‟s IMEI labeled on its shell. For example,
PC-505‟s IMEI is 240305001234567, then Ethernet channel‟s
ID is 2403050X1234567, and X can be 0~9. The first channel‟s
ID is 240305001234567, and this channel is fixed to connect
mServer only and not to connect cloud platform, and enable
virhub functionality. This channel is designed only for PLC
program update, and it can also be used to perform PLC-505‟s
remote configuration. The other nine channels are used to
connect PLC or other device with Ethernet interfaces.
Customers can choose the channels flexibly. For each channel,
configure PLC IP as the device‟s Ethernet IP, and PLC port as the
device‟s listening port, then tick “Enable”, press Save and
reboot PLC-505.
