Dear all , good day
Our system is S7315-2DP, and the DP is define as DP Slave, connected to DCS system from another company we transfer the data between two (master and slave) through Profibus MS protocol (slot 4,5,6)
And the system is working fine without any problem for more than three years.
Now, we need to send more information from PLC to DCS, so we add a new MS slot (slot 7), , and then I download it to PLC
The PLC after that is still working in Run mode but the BF and SF LED are ON, and all the data communication between DCS and PLC was lost.
