Auto-Logout
Feature Only
with RS232
If the serial option adapter is used and the RS232 port is chosen, auto-logout is
supported. If a programming panel is logged into the CPU via the serial port and its
cable gets disconnected, the processor adapter automatically logs out the port. This
auto-logout feature is designed to prevent a lock-up situation that could prevent
other host stations from logging in on other ports.
Auto-logout is not available for any RS485 port, including the RS485 option on the
serial option adapter. The user must log out of the processor using the programming
software.
