2.1 Brief Introduction of PCS-Studio

The PCS-Studio is the configuration and debugging software of PCS S series devices It provides

the following configuration functions:

 Device information configuration

Viewing and editing project name, user configuration file version, file modification time, etc

 Global function configuration

MOT selection, system configuration, function object activation/deactivation, etc

 Human-machine interface configuration

Single Line Diagram (SLD) drawing for LCD display, definition of LED indicators, shortcut keys,

user-level waveform recording, etc

 Communication configuration

Support of multiple communication protocols, including IEC 61850 (Edition 1 & Edition 2), IEC

60870-5-103, DNP3.0, Modbus, etc

 IO signal configuration

Binary inputs, binary outputs, AC and DC analogue inputs, etc

 User-defined logic programming

Complete and rich symbol library for user-defined logic programming

On the front panel of the device, there is a multiplex RJ45 port which is the debugging port for

connection to a portable computer Meanwhile, the CPU plug-in module is equipped with several

Ethernet interfaces which may also be used to communicate with debugging computer

2.2.1 Via Front RJ45 Port

By default, the IP address of front debugging port is “100.100.100.100” with the subnet mask

“255.255.255.000” If this address conflicts with any other Ethernet port on CPU module Through

the device front human-machine interface, please call up the modification menu by pressing the

key combination "◄ ＋ ◄ － ENT" under the default LCD display screen and change the default

address

2.2.2 Via Ethernet Interface on CPU Module

Firstly, a connection between the device and the computer must be established by setting the IP address and subnet mask of the corresponding interfaces Configure the IP address and the subnet

mask of corresponding Ethernet interface through MainMenu → Settings → Global Settings →

Comm Settings → General Comm Settings

The IP addresses and the subnet masks of device PC should be in the same network segment Take the second Ethernet interface (LAN2) on CPU module as an example:

LAN enabling setting [En_LAN2] = Enabled

“XXX” can be any value from 0 to 255 except 102

2.3 Validation of Configuration

To take effect of all kinds of offline configuration work through PCS-Studio, it is necessary to regenerate the device configuration file (*.devs) and download it to the device A reboot of device

is obligatory after the download for the validation of any modification

3

 Double click on the “Function” column to select an associated function from the drop-down

box

 Unlatched signal (500ms pulse, programmable)

 Latched signal (flip-flop mechanism, programmable)

The above two kinds of signals are configurable through programmable logics which are usually realized in a customized logic

user-configuration page created under the path: Project Node → Device Node

→ Program → Function_Logic → Customized Page Name

Drag a LCD signal under the path: "Variable DB → Source → CPU →

Page:PPC → Component:LCD", and drag a variable under the path

"Variable DB → Destination → Function_Logic → Page:**" Connect the source and the destination signals with "Link line" to create a customized

logic

to remove it

 In the “LED Colour” column, configure the LED light in three colours: green, yellow and red

 Each function key is equipped with a LED indicator Associate a source signal in the column

“LED Associated Signal” to control the ON/OFF status of this LED A source signal could be

a binary output of device function If the source signal is configured, the LED ON/OFF depends

on the signal state Otherwise, if the “LED Associated Signal” field is empty, the LED ON/OFF

status depends on the configured function
