Chapter 10 Using microSD Cards
Recipe Micro800 controllers support the Recipe feature and allows users to store and
load a list of data to and/or from recipe data files using the RCP instruction. It
also allows users to download, upload, and delete Recipe data on the microSD
card through the Connected Components Workbench software.
A maximum number of 10 recipe sets is supported for a Micro800 program.
Each recipe can contain up to 128 variables, with a maximum of four data
string variables per recipe. String variables can have a maximum of 252
characters. Variations of the recipe are stored in separate files with unique file
names. For more information on how recipes are stored on the microSD card,
see the Recipe Directory Structure
on page 170.
USINT(BYTE) Unsigned 8-bit integer value 0, 255
UINT(WORD) Unsigned 16-bit integer value 0, 65535
UDINT(DWORD) Unsigned 32-bit integer value 0, 4294967295

STRING
(2)
character string
(1 byte per character)
'"Rotation Speed"
DATE
(1)
Unsigned 32-bit
integer value
1234567
(Date variables are stored as 32-bit words, a positive number
of seconds beginning at 1970-01-01 at midnight GMT.)
TIME
(1)
Unsigned 32-bit
integer value
1234567
(Time variables are stored as 32-bit words, positive number of
milliseconds).
(1) BOOL, DATE, TIME data variables are presented in decimal digital format in the microSD Card. You have the option to convert this
format to a more friendly format. For example, use ANY_TO_STRING function block to convert BOOL data type (0, 1) to FALSE or
TRUE. You can similarly do the same for DATE and TIME data types.
DATE data type is presented in differential decimal digital value between system baseline time (1970/01/01,00:00:00) and current
date value. Unit is millisecond.
Time should be absolute time value. Unit is second.
(2) String data variables are enclosed in double quotation marks in the data log file.
The example below shows DSET1 using string variables and DSET2 using integers.
