Event - Mitsubishi Electric MELSEC iQ-R Series User Manual

Event

Event is a combination of the target data and event conditions.

Target data
Target data is the data to be saved with a time stamp to an SD memory card when a condition is satisfied by comparing the
device values that have been sampled from a CPU module with event conditions.
■Target data for event logging
The following data can be logged by event logging.
• Device memory in a control CPU
• Device memory in a CPU on another station in a multiple CPU configuration
• Device memory in a CPU on another station via a network
For details, refer to the following:
MELSEC iQ-R High Speed Data Logger Module User's Manual (Startup)
■Data type
Target data for event logging can be logged as the data types shown in the following table.
Data type
Bit
Word [Signed]
Double Word [Signed]
Word [Unsigned]/Bit String [16-bit]
Double Word [Unsigned]/Bit String [32-bit]
FLOAT [Single Precision]
FLOAT [Double Precision]
16bit BCD
32bit BCD
String
*3
Raw
*1 If the size is in odd number, the device point will be rounded up by adding 1 point.
*2 For double word device, the device becomes 2 points for each 4 bytes. The fraction should be rounded up to 2 points.
(Assign 2 points if size is 4 and 4 points if size is 5)
*3 A hexadecimal representation is converted to a string by byte unit, and it is output with a space removed.
(For start device D0, D0: 0x8A6B, D1: 0x41C2 4-byte raw type, 6B8AC241 is output.)
■String type data
Data is output in the following character codes depending on the file format to be output.
Unicode text files, binary files, report files: UTF-16 (little endian)
CSV files: ASCII
The considerations when logging string type data are as follows.
• Data character code of saved folder name settings, saved file name settings, and E-mail content settings is in ASCII format
regardless of the format in which the file is to be output.
• To specify the size (byte unit), consider the size required for the character code.
• To create character string data in a CPU module, use the instruction ($MOV or $MOV_WS) which supports character code.
• If the data with a different character code is output to the same file, some characters may be replaced with period (.) or may
be corrupted.
■Number of target data settings
Up to 1024 target data can be set for one "Event logging setting".
