B.3 FILE TRANSFERS APPENDIX B
Command and setting passwords each have a 30 minute timer. Each timer starts when you enter the particular password,
and is re-started whenever you use it. For example, writing a setting re-starts the setting password timer and writing a com-
mand register or forcing a coil re-starts the command password timer. The value read at memory location 4010 can be used
to confirm whether a command password is enabled or disabled (a value of 0 represents disabled). The value read at mem-
ory location 4011 can be used to confirm whether a setting password is enabled or disabled.
Command or setting password security access is restricted to the particular port or particular TCP/IP connection on which
the entry was made. Passwords must be entered when accessing the relay through other ports or connections, and the
B
passwords must be re-entered after disconnecting and re-connecting on TCP/IP.
