Checking the sensors starts to become involved. You need to know when the machine needs to "see" which sensor. On your control there is a PLC debug screen which lets you determine if the sensor is being "seen" by the PLC. You will need to determine what module inputs your sensors are wired to through the electrical schematics. As for your original issue, as someone had posted...insure you select a router on the process start (green light) window..also insure you selected a tool name that is exactly like the tool is described in the tooling data.
