2. Function description
Program memory sub-modules MS5/51 and MS55 are used to store the processor program.
The program memory sub-modules are inserted at slot X50 of the PM3, PT31, PT32,PM4,PM5 and
PM6 processor modules in the front panel recess.
The MS5/51 memory sub-module has a 2/4 Mbyte flash memory to store the engineering information
and 8 kbyte EEPROM for operating parameters which can be modified.
The flash memory is a non-volatile flash memory which can be erased and programmed electrically.
The MS55 memory sub-module has a 2 Mbyte SRAM for storing the engineering information and 8
kbyte EEPROM for operating parameters which can be changed.
The SRAM contents are buffered when the voltage fails via a battery inserted in the module. The
battery can be replaced without data loss.
The MS5/51 and MS55 memory sub-modules are based on the JEIDA / PCMCIA industrial standard
for memory cards with a 68-pin connection.

3. Application information
3.1. MS55 SRAM memory card
The MS55 memory card has a lithium battery
(CR2325, 3.0V/200mAh, 23mm * 2.5mm)
Supplier: e.g. VARTA Batterie AG Hannover
To change the battery, a pointed object is inserted in the hole at the upper end of the memory card.
The battery holder can then be withdrawn and the battery changed. Please observe the correct
polarity when replacing the battery. The battery must be replaced within 30 minutes to prevent data
loss. The battery should be changed every 13 months.
