Memory Cartridge
A user program can be stored on an optional memory cartridge installed on a MicroSmart CPU module from a computer
running WindLDR, and the memory cartridge can be installed on another MicroSmart CPU module of the same type. Using
a memory cartridge, the CPU module can exchange user programs without using a computer.
This feature is available on all models of CPU modules.
Memory Cartridge Type Number
User Program Execution Priority
Depending whether a memory cartridge is installed on the MicroSmart CPU module or not, a user program stored on the
memory cartridge or on the CPU module EEPROM is executed, respectively.
Memory Cartridge Specifications
Note: The optional clock car tridge (FC4A-PT1) and the memor y car tridge cannot be used together on the all-in-one type CPU
module. The clock car tridge and the memor y car tridge can be used together on the slim type CPU module.
User Program Compatibility
The CPU module can execute only user programs created for the same CPU module type. When installing a memory car-
tridge, make sure that the user program stored on the memory cartridge matches the CPU module type. If the user program
is not for the same CPU module type, a user program syntax error occurs and the CPU module cannot run the user pro-
gram.
Module Name Type No. Remarks
32KB Memory Cartridge FC4A-PM32
64KB Memory Cartridge FC4A-PM64
The 64KB memor y car tridge can be used on slim type CPU modules
FC4A-D20RK1, FC4A-D20RS1, FC4A-D40K3, and FC4A-D40S3 with sys-
tem program ver. 201 or higher only. The program capacity expands up
to 64,500 bytes (10,750 steps).
To edit user programs over 32 KB (5200 steps), use WindLDR ver. 4.2
or higher.
Memory Cartridge User Program Execution Priority
Installed on the CPU Module
The user program stored on the memor y car tridge is executed.
When the memor y car tridge does not store a user program, the user program
on the CPU module EEPROM is executed.
When a memor y car tridge is installed on the CPU module, the user program
can be downloaded from the memor y car tridge to the CPU module by designat-
ing in WindLDR Function Area Settings. To per form user program download
from the memor y car tridge, use CPU system program ver. 210 or higher and
WindLDR ver 5.31 or higher.
Not installed on the CPU Module The user program stored on the EEPROM in the CPU module is executed.
Type No. FC4A-PM32 FC4A-PM64
Memory Type EEPROM

Hardware for Storing Data CPU module
Software for Storing Data WindLDR WindLDR ver. 4.20 or higher
Quantity of Stored Programs One user program can be stored on one memor y car tridge.
• Compatibility of User Program with CPU Modules
When a memory cartridge contains a user program for higher functionality, do not install the mem-
ory cartridge into CPU modules with lower functionality, otherwise the user program is not exe-
cuted correctly. Make sure that the user program in the memory cartridge is compatible with the
CPU module.
