*1 Up to 3 bytes are added to the total file size so that the size will be a multiple of 4 bytes.
File size
Approx. 4050 bytes minimum (only the END instruction + 500 steps reserved for online program
change)
Approx. 4900 bytes minimum (non-processing FB + 500 steps reserved for online program change)
744 bytes minimum
112 bytes minimum
The size differs depending on the module used. For example, the size is 1036 bytes at minimum
when the Ethernet function is used.
The size differs depending on the module used. For example, the size is 65572 bytes when the
predefined protocol support function is used with the Ethernet function.
The size differs depending on the module used.
124 bytes minimum
220 bytes minimum (when a device comment with 20 characters is set in a device)
Approx. 140 bytes minimum (when the initial value of a word device is set)
Approx. 660 bytes minimum (when a word-type global label is set)
Approx. 140 bytes minimum (when the initial value of a word-type global label is set)
2048 bytes minimum (when the setting capacity is 1K words)
1024 bytes minimum (when the setting capacity is 1K bytes (default setting is 131072 bytes))
2048 bytes minimum (when the setting capacity is 1K words)
The size differs depending on the size of the file to be written.
142 bytes (When the setting is configured so that one-word data is collected in a binary file at each
scan in continuous logging)
1192 bytes (When the setting is configured so that one-word data is collected in a binary file at each
scan in continuous logging only for setting No.1)
1224 bytes (when the save file name is "MEMDUMP_00")
