AS Series Module Manual
10-26
Example:
The address area used is within 500/500 bytes. But you need to add bytes used on IO Production Status (IOPS) and IO
Consumption Status (IOCS) of each module too. Here the example shows the address area of the input module is taken
by 500 bytes (data length) + 4 bytes (Slot 0) + 2 bytes *7 (7 I/O modules) + 1 byte (Slot 1) = 519 bytes. The same
example shows that the address area of the output module is taken by 500 bytes (data length) + 4 bytes (Slot 0) + 2
bytes *7 (7 I/O modules) + 1 byte (Slot 9) = 519 bytes. The data exceeds the total permitted maximum data length of
500/500 bytes. An error message appears as the image shown below by TIA Portal.
Note: this error message shown indicates the IO data length is abnormal.
