Product's Character:

The following has to be observed for project planning and start-up:Programming
is performed using AC31 programming software, which can be run on commercially available IBM compatible PCs (see documentation for the programming system 907 PC 331)The processor processes the user program contained in the RAM. It is loaded into the RAM via the serial interface COM1/COM2 or via the SmartMedia Card and can also be changed there. An additional save command is used to save the program in the Flash EPROM.Note: In the course of the following operations Power ’ON’  RUN/STOP switch from STOP --> RUN  Program start-up with programming system Cold start of the PLC Warm start of the PLC
