  1. 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
  2. Problem is : when I disable ALARM, after reseting PLC, ALARM is enabled again?
  3. Dear All, Alarm status viewer is great option, but .. Is it possible to retain status "DISABLE" after power loss? Are there any system bits that can make this possible? Kind regards,

  8. 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,
