General points
CAUTION
MODULE DESTRUCTION
If there is no PCMCIA memory extension card inserted in the Premium PLC, do put in place the front panel protective cover.
Failure to follow these instructions can result in injury or equipment damage.
TSX P57 1•4 to 4•4 PLCs
Memory cards located in slot A (top)
The extraction (or absence) of the cover or memory card and clip causes the PLC to stop without saving the application context. Module outputs switch to fallback mode.
Inserting the cover or memory card with clip will cause the PLC to perform a cold start.
WARNING
UNEXPECTED BEHAVIOUR OF APPLICATION
Ensure that the right user application is contained in the memory card before inserting it into the PLC.
If the program contained in the PCMCIA memory card includes the RUN AUTO option, the processor will automatically restart in RUN after the card is inserted.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Memory cards located in slot B (bottom)
The Type 3 PCMCIA memory card should be inserted into slot B of the processor while the PLC power is off. Ignoring this warning could cause the processor to malfunction.
WARNING
UNEXPECTED APPLICATION BEHAVIOR - PCMCIA CARD PROTECTION
It is essential that any modification of the position of the PCMCIA card write protection switch be performed when the controller is powered down.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Memory cards located in slot A (top)
The extraction (or absence) of the cover or data or file-type memory card (*) and caddy has no effect on the operating modes of the PLC.
(*) in this case, the read/write functions of the memory card indicate an error if the application is in RUN.
The extraction of the memory card containing the application with its caddy causes the PLC to stop without saving the application context. Module outputs switch to fallback mode.
Inserting the memory card containing the application with its caddy will cause the PLC to perform a cold start.
