The ROPEX visualization software can be used to change the configuration of the connected RESISTRON/CIRUS temperature controller and document the actual heatsealing parameters. The software communicates in different ways, depending on the controller: RES-430 (as of SW revision 007): The visualization software communicates with the RES-430 via a serial interface on the PC (COM port). The serial piggyback module (MOD 33 modification) must be installed on the RES-430 for this purpose. It is connected to the PC by means of a serial data cable. The functionality of the visualization software depends on the connected controller.
