Many reasons can causing this problem, e.g. terminating resistors, cables... Although the MPI/RS232 Adapter can be used, I would suggest you to use a CP5611. In the chapters 2.2.3.1 - 2.2.3.3 you can find further informationshow to fulfil the requirements: http://support.automation.siemens.com/WW/view/en/18797552 |
