Transferring Application Files with
Chapter 5
User PROMs
5-7
You can download and store PanelBuilder application files in the optional
EEPROM. The EEPROMs can then be installed into PanelView 1200
terminals on the factory floor.
Series C and earlier PanelView 1200 terminals contain two sockets for
EEPROMs. Series D, E, and F terminals have only one socket for one
EEPROM.
Whether you can use the EEPROMs to back up your application file
depends on your terminal version and the application’s user memory limit:
In Series E and earlier terminals, you can use the user EEPROM for
application backup or to increase the memory available for the
application from 64K to 128K. An EEPROM that is used for application
memory can’t be used to back up the application.
Also, your application file’s user memory limit must be defined as
59,904 bytes or 62,976 bytes. For details on choosing memory limits,
refer to the PanelBuilder Development Software User Manual or the
PanelBuilder 1200 Configuration Software for Windows User Manual.
In Series F terminals, the EEPROM is no longer used for extended
memory, since standard available memory is 128K. Thus, even if the
application file has been created with one of the larger memory limits,
you can still program the EEPROM, if the EEPROM size is 128K.
Programming Methods
You can program an EEPROM in two ways:
Via downloading—If an EEPROM is installed in the empty socket in
the PanelView 1200 terminal, an application will automatically be
copied into the EEPROM when it is downloaded to the terminal. This
method does not require a PROM burner.
The download can be via Upload/Download cable, Pass-Through
Download over Data Highway Plus, or PCMCIA memory card (Series F
terminals only). Refer to the appropriate chapters in this manual for
detailed instructions on downloading.
Important A Series F PanelView 1200 terminal accepts either a 64K or
128K EEPROM. The 128K chip accepts an application of any size. The
64K chip accepts only applications with a memory limit of less than
64K. If the application is too large for the EEPROM, the EEPROM is
invalidated. This ensures that, if an old application is present in the
EEPROM, it cannot overwrite the application just loaded into memory.
