Question
Timeouts occur frequently when connecting PLC and Ethernet. Is there a solution?
Answer
When a timeout occurs, there may be various factors such as network load, noise, or equipment malfunction. The following is a list of factors that have been reported in the past for your reference (these are just examples of reports and have not been verified by the manufacturers or models listed).
When using Buffalo HUBs with model number "BUFFALO LSW-TX-xxx", there is a phenomenon that communication (especially UDP communication) becomes unstable. If you are experiencing instability with this model, please check the network status with another HUB and try to isolate the cause.
When multiple applications such as ladder editing tools and touch panels from other companies are connected to a single PLC, timeouts may occur. In such a case, please try to use only one connection and try to isolate the cause.
Is the cause in the PC, the communication path, or the PLC? The most common cause is the communication path, so try to isolate the cause by using a crossover cable to connect directly without going through the HUB.
