For bitbus communication the bitbus card has to be installed on the PC. Otherwise a free RS232 serial interface will be used for the communication.
The IOTOOL32 Pro version 2.30 by Brodersen has to be installed. Without this software the driver will not work.
Copy the driver file Sys2000.EXE and Sys2000LOG.EXE to the current zenon directory (unless it is already there).
