Now with pass-through function, HMI can work like a converter so that PC can send signal to PLC through the Ethernet port on HMI, which minimizes the need for hardware adjustment, and allows modifying PLC program on PC.Pass-through may be achieved through the following are three different ways for a PC to connect HMI via Ethernet.

In this case, Ethernet Pass-through allows the PC application to communicate with a PLC in different domain.

PC can control PLC after entering PLCs IP address in the corresponding field.

Codesys Hmi License Agreement IsPrior to installation, the end-user license agreement is to be accepted. They extend the functionality of the CODESYS Development System and the CODESYS Control SoftPLC systems. Codesys Hmi Software License Container BoundFor each product, there is a defined license mode per workstation or per target device: Workstation license (soft- and hardware-based): Licensing is performed either through the CODESYS Soft Container (a software license container bound to the workstation PC) or through the CODESYS Key (a USB dongle providing additional functions for security purposes). The latter can store up to 4,000 licenses and allows for using workstation licenses on different workplaces. Single device license (for products bearing the suffix SL for Single License) The license is stored directly on the target device. For this license mode, the runtime system CODESYS Control V3.5 SP4 or higher or a SoftPLC from the CODESYS Store has to be installed on the device. Each user of the device can work with the same license, but the license cannot be transferred to another device. Alternatively, the license can be stored on a CODESYS Key (USB dongle) which is connected to the device. By connecting the CODESYS Key to another device the license can be transferred to other devices. Licenses can be stored on the CODESYS Key or on the device directly during the purchasing process in the CODESYS Store, afterwards in the CODESYS Development System or on a special web interface (License Central under ). Each device programmable with CODESYS is subject to license fees known as runtime royalties. For documentation purposes, each manufacturer is awarded a license certificate for the toolkit and the add-on products purchased. Fees for add-ons to CODESYS Visualization and the integrated MotionControlCNC Toolkit are added to the license fees for the runtime system used. The license is stored directly on each device by means of WIBU CodeMeter Technology. For this purpose, special accounts (tenants) are booked and managed in the CODESYS Store. The licensing depends on time and usage, among other things on the number of controllers administered and data volume consumed.
