Maybe I did not realized the point. I realized: If I have programmed ALARM, but don't want this ALARM to be active than I disable this ALARM in alarm management. Obviously, this is not the point. Kind regards

Dear All, I am working on a project where I have UnilogicUnistream MASTER which read/write data from 10 slaves over CPU's 485 port. I know that Unistream OPLC can be and MASTER and SLAVE at the same time, but I am wondering is this possible over the same 485 communication port? Example: SCADA is MASTER to OPLC, and OPLC is MASTER to 10 slaves Example: SCADA(M) --- OPLC(S & M) --- DEVICES in the FIELD (S) So please can somebody to answer me and explain a little bit? Do I need maybe one more 485 com module? Or I can do it somehow over the same com port? Kind regards,
