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.
