Error message 103 at the backplane bus of the controller
What happens?
The following error message is reported: I/O module msg. 103: Not all I/O modules are available (Master queue operation error).
When does the behaviour occur?
Many I/O modules are connected to the backplane bus of the controller. As a result, more than 240 bytes of input or output are occupied in the process image.
Which products are affected?
Controller 3200C
Controller c300
Short-term measures:
Reduce the number of IO modules so that less than 240 bytes in the input image and 240 bytes in the output image are occupied.
