2.1 Ordering Code

PCS S series device can select the hardware configuration and software functions of the device

through the auxiliary tool “PCS-Torch”, and a corresponding MOT (Market Ordering Table) serial

code will be generated

The MOT serial code consists of 9 parts, including:

 Device type: indicates the device type

 U field: indicates application scenario

 A field: indicates firmware type, which can be standard version or regional version

 R field: indicates firmware version

 S field: indicates software functions

 C field: indicates chassis structure and installation

 PWR field: indicates the voltage level of power supply plug-in module

 H field: indicates plug-in module configuration

 MOT version: indicates MOT version

The display format is shown as below:

H field

MOT version

Click the button "Default", all options will be chosen as default value directly Click the button

"Import", an existing MOT file (*.xls) can be directly imported into the corresponding device type of

PCS-Torch

After selecting the specific function, click the button “Complete” to display the currently selected

configuration information, is shown as below:

Click the button "Copy", MOT (Market Ordering Table) serial code based on selected information will be copy to the clipboard Click the button "Export", MOT and hardware configuration can be

exported as a file (*.xls)

2.2 Selection Information

A MOT serial code consists of several bits, and the specific meaning of each bit is as below

2.2.1 Device Type

For a specific device, the device type is fixed, such as PCS-902S, so it is not need to be chosen

2.2.2 Application Scenario (U Field)

The corresponding application scenarios are selected according to the actual protected objects by

the device Only one kind of application is available, so it is chosen as "2 terminal line" fixedly

2.2.3 Firmware Type (A Field)

The firmware type is used to select between the standard version program and the regional

version program Only the standard version program is available, so it is chosen as "Standard"

fixedly

2.2.4 Firmware Version (R Field)

The firmware version is used to select required program version If there is no special version

requirement, the latest version can be chosen, i.e., “Latest version” Otherwise, the specified

version can be chosen

2.2.5 Software Functions (S Field)

The software functions are determined by four parts: "Software", "Language", "Protocol" and

"Sampling mode"

1 Software

The option is used to select the required protection functions, which is used in conjunction with the

application scenario option

Different options correspond with different combinations of protection functions, which can be

viewed through the button "Software Functions" in PCS-Torch
