2 Software Maintenance

Each LNC-520i serial controller will be accompanied with an INSTALL DISK which will help user during
program installation and maintenance.

2.1 LNC-M520i Installation Description

CNCMINST full-function installation/maintenance program provides system installation, program upgrade
and system restore functions for LNC-520i series.

2.1.1 Installation Program Guide

Executing g.bat file and the below screen will appear：

Pressing any key and the below menu will occur：

LNC Technology Co., Ltd. 3

LNC-M520 Series

Software Maintenance

Following is the introduction about the timing of these parameter（before executing，please refer to HOW2）：

1. First fully（Total）installation
This function is used for the first time fully installation and/or harddisk recovery. Generally speaking,
LNC-520i is already installed into every LNC-520i series controller before going in the market. Therefore,
unless the harddisk is “FORMATE”, there is no need to use this function.

Note1：To prepare a BOOTABLE H.D as C:DRIVE, please refer to the following:

a. Preparing a FORMATED HardDisk
b. Setting the BOOT SWQUENCE FOR the IPC BIOS As A: DRIVE first.
c. Putting the O.S UTILIT floppy disk into A: DRIVE (IBM PC DOS V7.0）
d. Press CTRL+ALT+DEL or RESET to reboot the IPC from A: DRIVE
e. Please follow the instruction and execute [1] QUICK MAKE AN BOOTABLE H.D（C）
f. When the above are completed, please reboot the IPC and restore the PC BOOT SEQUENCE

as C ONLY.

Note2：The present DOS is IBM PC DOS 2000

2. Maintenance
User have 3 choices here:

1. PCScan：Check out if there are viruses in the disk.

2. DISK Doctor：Scan the disk and check the disk has been destroyed or not.

3. DEFRAG：Defrag the disk.

4. Quit
Exit Installation windows and return to DOS system.

2.1.2 System Software Maintenance and Upgrade

For software update, users only need to follow the instruction to replace specific files with the newest files in
the installation disk. Please make a copy of the prior version installation disk. Then, run [Gbat] to choose the
correspondent function.

3.2 I/O card SIO 1520

Besides to 20 Input/16 Output, I/O module of this system can be extended to 128 Input/128 Output at most.
Connecting chart shows as below:

Slave I/O board provides Jumper selection for two output signal methods. One is Source type and the other
one is Sink type. The output voltage is 24V and every point’s maximum pushing function is 80mA. To
determine input signal, the determination for High (1) is 15 ~ 28V, the determination for Low (0) is 0 ~ 4V and
the input voltage is 10mA. The JPI on the SLAVE mothor board will connect DC24V power from outside.

3.2.1 I/O Card Specification

To reduce IO cable, we can complete I/O transmission by motion control card with I/O card. An I/O card can
be divided to SIO 1520 master board（or S1O 1540 master board）and SIO 1530 slave board.

One SIO card can offer 40 input and 32 output, and SIO 1530 extension cardcan offer 24 input and 32 output;
in the other word, 1 set of I/O master board and slave board can offfer 64 input and 64 output totally. LNC
600 can string up 2 set of SIO master board +SIO slave board by using RIO connecter, so it can offer 128
input and 128 output at most.

3.6.1 Double CF Cards

Using double CF card to handle the data backup job. The following introduces functions of double CF cards.

3.6.1.1 Auto Back Up

Dobule CF cards will auto backup files in the following two timings:

1. After entering into the system, the CF card will auto backup files under “machine” menu.

2. Auto backup internet setting files when executing internet function（C:\NET\2NET.BAT）.

3.6.1.2 Soultion when Not Able to Enter into System

Please using any of the following methods to enter into the system:

1. If not able to enter the system, please key-in res8 after C:\> and exit the system. Then, should be able
to enter the system. Please do NOT take the second CF card out of IPC.

2. If not able to start the system, pleae take the first CF card out of IPC. The second CF card will enable
the system after rebooting.

3. Pleae contact our service person. Pou Yuen will mail a brand new CF card for user to replace the old
one. But, please do NOT take the second CF card out of IPC.

C Bit 000 CYCLE START

In MEM or MDI mode, to set C000 from OFF to ON actuates the system

START status. At the same time, the system sets S000 to ON to notify
cycle start light. If the system is in FEED HOLD or BLOCK STOP status, the system will set
S000 to OFF to notify the ladder to turn off the feed hold light first. However, C000 is not
accepted by the system in the following conditions:
a. When the system is not in MEM or MDI mode.
b. When the system is already in “NC NOT READY or “CYCLE START status.
c. When the system is having an alarm.

C Bit 001 FEED HOLD

In MEM or MDI mode and also in CYCLE START status, to set C001 from OFF to ON actuates

the system to enter FEED HOLD status. At the same time, the system sets S000 to O
notify the ladder to turn off the cycle start light, and also sets S001 to ON

Attention：

1. For read only items, if Ladder sets C64 to 1, NC will ignore it. Using the same principle for the writing
items, if Ladder sets C64 to 0, NC will ignore it.

2. Macro variables belong to DOUBLE type. But the present Ladder can only take care of the value in INT
type. So if Ladder reads macro global variables via PLC Window, NC will check whether or not the
macro global variable value is between -32768 ~ 32767. If yes, the macro global variables will change
to INT type and then enter into the corresponding R register. If no, then the alarm【OP 1019 DESIRED
MACRO VARIABLES OVER RANGE】will occur.

3. Using R61 and R62, Ladder can read/write multiple macro global variables (maximum 8 variables)
continuously. Example: set R60 to 3, R61 to 200 and R62 to 5. When C64 is OFF, it means the total
current value of the designated reading/writing @200 ~ @204, total 5 macro global variables. But, if
(R61 + R62 – 1) > 500, then alarm message【OP 1018 DESIRED MACRO GLOBAL VARIABLES NOT
EXISTED】will occur.

4. Macro local variables not able to execute read and write via PLC Window.

5. The reading parameter value must be an integrate number (INT) or long integrate number (LONG). But
the present Ladder can only take care of the values in INT type. So if Ladder reads parameter value via
PLC Window, NC will check whether or not that parameter value is between -32768 ~ 32767. If yes, the
parameter will change to INT type, and then enter into the corresponding R register. If not, the alarm
message 【OP 1022 DESIRED PARAMETER VARIABLES OVER RANGE】 will occur.

6. Using R61 and R62, Ladder can read/write multiple parameter variables (maximum 8 variables)
continuously. Example: set R60 to 3, R61 to 200 and R62 to 5. When C64 is OFF, it means the total
value of the reading parameter variables 0200 ~ 0204, total 5 parameter variables. If it is over the valid
parameter range, the alarm message【OP 1023 DESIRED PARAMETER VARIABLES NOT EXISTED】
will occur.
Valid parameter variable range： 0 ~ 220，300 ~ 899，1000 ~ 1200。

7. Parameter is not able to execute setting via PLC Window.

1. OP 1018：DESIRED MACRO GLOBAL VARIABLES NOT EXISTED.

Bit0：1 means 1 in 1, 2, 4, 8, 16, 32 and so on
Bit1：1 means 2 in 1, 2, 4, 8, 16, 32 and so on；
Bit2：1 means 4 in 1, 2, 4, 8, 16, 32 and so on；
Bit3：1 means 8 in 1, 2, 4, 8, 16, 32 and so on；
Bit4：1 means 12 in 1, 2, 4, 8, 16, 32 and so on；
So, if want to set a certain Bit to 1, only need to adding up the corresponding value into the parameter.
For example, if want to set both Bit1 and Bit3 to 1, the setting value of this parameter is 10（2 + 8）.
