PCMCIAmemory extension cards are used to extend the internal RAM capacity of
Premium processors.
Some of the cards can also be used on Modicon Micro and Modicon Quantum
processors. Depending on the model, these cards are designed to hold:
b
The application program, symbols and constants
b
Additional application data
b
Or both
PCMCIAmemory extension cards
All the cards are inserted into PCMCIA slot no. 0, which is the upper slot on Premium
processors.
Two of these SRAM data storage memory cards can also be inserted into slot no. 1,
which is the lower slot on Premium processors.
These cards support three types of storage:
b
Application storage: program, symbols and constants in a common area of
(128
Kb to 7168 Kb, depending on the card model):
v
TSX MRP P
ppp
K
for SRAM memories
v
TSX MFP P
ppp
K/M
for Flash EPROM memories
b
Storage of the application and additional data, comprising an application area
configurable from 192 Kb to 7 Mb and an additional data storage area which
therefore varies from 7 Mb to 0 Kb. The configurable cards are:
v
TSX MRP C

K/M
for Flash EPROM and SRAM memories
b

memory cards.
These cards use two technologies:
b
Battery-backed SRAM
Used in particular in the application program design and debugging phases. These
cards allow:
v
all of the application's transfer and modification services in online mode
v
Additional data storage
The memory is protected by a removable battery built into the PCMCIA card. A
second, auxiliary battery, provides backup so that the main battery can be replaced
without data being lost.
b
Flash EPROM
.
Used when debugging of the application program is complete. It enables:
v
Backup battery life restrictions to be overcome
v
Aglobal application transfer to be performed
If it is used, the application cannot be modified in online mode.
Programmodification in online mode
Only extension cards on which the program is stored in SRAMmemory (TSX MRP
P
ppp
K/M and TSX MRP C
ppp
K/M) support online program modification
Users of processors fitted with memory extension cards who wish to modify or add
program data in online mode must follow the two recommendations below:
b
Structure the application program in in several, reasonably-sized sections
b
Where possible, select one of the two extension cards recommended in the table
