Operation At Recipe Execution - Mitsubishi Electric MELSEC iQ-R Series User Manual

Operation at recipe execution

When a recipe execution operation request occurs, the value of 'recipe execution information' (Un\G810) in the buffer memory
will become '1'. When the read/write processing of the recipe data is completed, the value of 'recipe execution information'
(Un\G810) will become '0' and the recipe execution operation will be completed.

information (Un\G810)
• A recipe execution operation request is performed during the recipe execution operation
When the next recipe execution operation request occurs during the recipe execution operation, the new request cannot be
processed, and an error will occur.
• The recipe execution operation is performed at the same time
Only one recipe execution operation is processed and other recipe execution operations will be in errors. The recipe file that is
currently being processed can be checked in the buffer memory. (Page 316 Recipe file area (Un\G810 to 841))
Precautions
• Recipe operations cannot be executed when the operation status of the module is 'stop', or when the access status of the
SD memory card is 'access stop'.
Check the operation status of the module from the following:
OPR LED and CARD RDY LED
Input signal (X1, X2, and X5) and buffer memory ('Module operation status' (Un\G20))
Module diagnostics and SD memory card diagnostics
• A file with an extension of ".TMP" will be created in the RECIPE folder of the high speed data logger module during the
process of writing the recipe.
• The file with the extension ".TMP" may remain in the RECIPE folder of the high speed data logger module when the power
of the programmable controller system is turned OFF during recipe execution operations.
• Store only files with the extension '.CSV' in the RECIPE folder of the high speed data logger module. The files with other
extensions than '.CSV' may be deleted during the recipe execution operation.
• The file size of one recipe file is up to 512 KB.
• The recipe execution operation starts performing from the beginning of the recipe file. It may not operate according to the
settings when the device reads duplicate recipe files.
• The recipe execution operation can be performed only when control CPU is the target CPU module. It cannot be executed
from CPU modules other than the control CPU.
• Do not access the Recipe file to overwrite or delete during the recipe execution operation.
• Do not power OFF or reset the CPU module during the recipe execution operation. The Recipe file being created may be
damaged. Power OFF or reset the CPU module after confirming the completion of the Recipe processing.
• If Float (Single Precision) or Float (Double Precision) is specified to the data type, the values of the range which can be
used in the CPU module can only be set for reading. If the value which cannot be used in the CPU module is read, the
following value will be stored to the device in the CPU module.
If a positive value is set: "0" is stored.
If a negative value is set: The value that only the first bit of the last device is turned ON is stored.
Ex.
When D0 is specified in the device, Float (double precision) is specified in the data type, and values outside the range of
negative values are set in the device value.
Store the value when only the start bit (15th bit) is ON to D3, and store '0' to D0 to D2.
