Quickstart Projects for Data
Log and Recipe Function
Blocks
The following sample quickstart projects provide step-by-step instructions on
how to use the Data Log and Recipe function blocks in Connected Components
Workbench to generate and manage your recipe files and data logs.
IMPORTANT RCP Function Block Execution
• There are three possible states for Recipe function block: Idle, Busy,
Complete (Complete with Succeed and Complete with Error)
• For one Recipe function block execution, the typical status starts from
Idle then Busy and finishes with Complete. To trigger another function
block execution, the status needs to go back to Idle first.
• Idle status changes to Busy status only when Enable input signal is in
rising edge. Complete status enters Idle status when Enable input
signal is on Disable status.
• RWFlag, CfgId and RcpName input parameters are only sampled at
Enable input parameter's rising edge when a new function block
execution starts. During function block execution, input parameters of
RWFlag, CfgId and RcpName are locked and any changes are ignored.
• When the function block execution finishes, the function block status
changes from Busy to Complete. At this stage, if input Enable is False,
function block status changes to Idle after staying as Complete for
exactly one scan time. Otherwise, function block status remains
Complete until input Enable changes to False.
• Recipe function block file name supports a maximum of 30 bytes in
length, and only supports upper and lower case letters Aa…Zz,
numbers 0…9 and underscore (_).
• The RcpName input parameter does not allow file extension (for
example, .txt) to be added to its value. The recipe data file is written
to the microSD card with the .txt extension.
• There are separators in between every data variable in the recipe
data file which is defined during configuration in Connected
Components Workbench. Redundant tab, space, carriage return and
line feed characters are strictly not allowed.
See Supported Data Types for Data Log and Recipe Function Blocks
on page 110 .
• Double quotes are not allowed within a string in a recipe file.
