LOGIC PLCs Password Protection
NOTE: Direct
LOGIC PLCs support multi-level password protection of the ladder program. This allows
password protection while not locking the communication port to an operator interface. The multilevel
password can be invoked by creating a password with an upper case "A" followed by any variation of seven
numeric characters (e.g. A1234567). Please refer to the specific PLC user manual for further details.
