Hi All, Is there a better way to prevent (lock-up) on-line editing of a Safet PLC application program (designed to meet SIL2) other than the usual password protection and RUN / REMOTE (Program) key?
Paul Bennett, Can you please respond to this query?
Can anyone tell me what protection features are offered for Safety PLCs such as QUADLOG, HIMA, FSC, TRICONNEX / TRIPLEX? Thanks in advance, Raj Sreenevasan
