, which will cause the falling edge (slowing down) time of the signal to be longer, thus causing bit (width) identification error. To realize the automation of the can FD bus test, Fengqiu has launched the can FD consistency test system. This system can not only complete the test of the physical layer, data link layer and application layer of the can FD network, but also formulate the corresponding network management test according to the customer's needs to verify the network sleep and wake-up and network management behavior. It is an excellent and convenient automatic test system- Automation is an automatic test management software based on ATX, which is used to test the performance of electronic control unit (ECU). Q-automation is an automatic test software that supports integration of can FD physical layer, data link layer, application layer and network management. It supports more than 100 conformance test items. Today's IO link communication standard has been implemented in the direct machine environment. At present, many field devices are also equipped with processors that can provide information other than user data (such as diagnostic data or device information).
IO link can read periodic
