5.3.5.5 Storage
Use this page to view details of the control unit's memory state. The most important information for you will be the
flash memory state (green highlight) and the state of the external SD card (blue highlight), if any.
You will find the one or several USB memory sticks connected (via a hub if several) in column "/media/usbx". The
x marks the order in which the sticks have been mounted (i.e. 1 if one stick is connected).

5.3.5.6 System Dump
This page allows you to create an image of the control unit's entire diagnostics realm. Use this function to analyse
errors occurring in an application or the control unit. We recommend creating the image file immediately after the
error occurred, i.e. without restarting the control unit first. It may take several minutes to create the image file. Once
it is available, the browser will provide it for download. Save this file and send it to Parker for analysis.
5.3.6 Logout
Find the logout link in the bottom right corner of the screen.

Description
/flash
Unit's internal flash memory
/flash/plc
CODESYS V3 root directory. Also mounted at /home/plc.
/flash/plc/applications
Location of the CODESYS V3 application
/flash/plc/applications/fonts
Location of some fonts which needs to be created once if you intend to use your own fonts.

uploaded via FTP.
/media/sd
External flash memory (SD card); only available if a SD card is used.
/media/usb1
External USB memory; only available if a storage medium has been plugged in.
File System and Folder Tree
Most of the control unit's file system folders and files can either not be accessed or just read by the user. To be able
to use certain control unit functions, however, there are some directories that end users have write and use access to.
5.4.2 Service Mode
Service mode differs from normal operation in the following points:
• CODESYS V3 Runtime will not run, i.e. no control program will be running.
• The factory defaults will be loaded when configuring the network to ensure that every control unit can be ad-
dressed by a unique IP address. Refer to section 5.3.2.1 to learn more about this kind of network configura-
tion.
• Underneath the name of the control unit, the web interface will display "(maintenance)" instead of "(plcactive)".
Service mode is enabled by turning off PAC120. Now press and hold the button to restart PAC120. Keep pressing
the button until Run/Stop lights up yellow every 2 seconds.
5.4.3 Installing more Fonts
By default, DejaVu series fonts are installed. If you wish to use other fonts such as Windows fonts for your Web-
Visu or TargetVisu visualisations, you may copy any set of Truetype fonts (*.ttf) to folder "/flash/plc/applications/
fonts/" and use them afterwards.
If you have not used any own fonts yet, you will have to create this folder once. We recommend running the con-
trol unit's FTP server application and downloading the fonts into the control unit via FTP.
Attention: For system reasons, you will have to use lowercase letters for the font file extension because the system
will otherwise fail to recognize the file and you may have to rename the file. For example, be sure Arial unicode font
file is called "ARIALUNI.ttf". The control unit will not recognize "ARIALUNI.TTF" or "ARIALUNI.Ttf".
Attention: You can choose to use the on-board or additional fonts. To make parallel use of your own and the on-
board DejaVu fonts, first of all download the DejaVu fonts from directory "/var/lib/fonts" or via the web interface
and upload them to folder "/flash/plc/applications/fonts/" together with your own fonts.
Note
Many fonts you may know from daily PC use are subject to a license! Arial, for example, is a Microsoft font covered by your
Windows license. Before using alternative fonts, please verify that they non-licensed freeware or that you own the license.
5.4 System Functions
5.4.1 FTP-Server
Run the FTP server of PAC120 to allow an FTP client to access the controller. Refer to section 5.3.2.5 menu Item
"FTP server". FTP lets you exchange recipe data with the control unit, for example.
