The best option is to supply the PROFINET interface component along with a system simulator that runs a full implementation of the application software without the large, heavy, or power- hungry physical apparatus. Another alternative to certify the device is to inquire about on-site testing services. For example, PITLs are allowed to perform an on-site test if the device meets one or more of these criteria: Device or any device part exceeds the maximum transport size of 1800 x1500 x 700 mm Total transport weight of the device is greater than 300 kg Device utilizes or is technically possible to adapt it to utilize input power higher than 32 A, 400 V AC, 50 Hz, or corresponding values for countries outside Europe
