2.2 CC-Link IE Field Network Configuration
Data link error in all stations when starting a personal computer
Errors occur in all stations when a personal computer is started.
This is because the line between P1 and P2 of CC-Link IE Field Network board is disconnected under the following
conditions.
• The power of the personal computer is turned OFF. (The line becomes in a conduction state when the power is turned ON.)
• A reconnection is in progress when starting a board driver.
As a result, the following reconnection occurs and causes an error in all station.
• A reconnection of CC-Link IE Field Network board installed in a personal computer.
• A reconnection of station which is located beyond the CC-Link IE Field Network board from the point of the master station.
If multiple boards are installed in a single personal computer, this symptom occurs for the same number of times as the
number of installed boards.
