There are several reasons for the 'Network Skipped' message being displayed online.
- Are all segments scheduled?
- Is the PLC running in optimized mode?
- Hot standby system?
- SKP blocks used in Ladder logic?
- Modbus communication. This can be a MB timeout. Jumper out the handshaking on the cable.
- If this occurs in an Equation network, it could be a old Proworx Nxt bug. If the value in the Equation Network register goes below 0, Proworx NxT displays this message.
