Files
This section lists the files used by the SIL2 Process CPU.
File types and storage memory
The following table summarizes the types of files stored in the SIL2 Process CPU and storage memory.
: Required, : Can be stored, : Cannot be stored
File type
Standard program
Standard FB file
Standard CPU parameter
System parameter
Standard module parameter
Module extension parameter
Module-specific backup parameter
Memory card parameter
Device comment

Safety FB file
*6*7
Safety CPU parameter
Safety module parameter
Safety global label setting file
Standard/safety shared label setting file
*1 mmm represents the start I/O number (first three digits in four-digit hexadecimal representation) of each module. For the SIL2 Process
CPU, it will be 3FFH. Also, nn represents the consecutive number (two-digit hexadecimal representation) of module extension
parameter files of each module.
*2 Can be stored but cannot operate as a function.
*3 When this file is stored in the built-in memory of the SIL2 Process CPU, it is divided into program memory and data memory and stored.
( Page 106 Configuration of a program file)
*4 Module extension parameter for the protocol setting, storing protocol setting information in the predefined protocol support function
*5 One or more of either standard program or safety program is required.
*6 The file is also stored in the SIL2 function module.
*7 This parameter relates to safety control inside the CPU parameters. ( Page 936 Safety CPU parameters)
This item is yellow in the engineering tool CPU parameters.
*8 The module-specific backup parameter is a file for storing the save or restore data of the module to be replaced by the online module
change function. For details, refer to the manual for the module used.
