Controller Security
Micro800 security generally has two components:
• Exclusive Access that prevents simultaneous configuration of the
controller by two users
• Controller Password Protection that secures the Intellectual Property
contained within the controller and prevents unauthorized access
Protected Mode To maintain the secure operation of your Micro800 controllers, operations
that can disrupt controller operation are restricted based on the controller
operating mode.
Exclusive Access Exclusive access is enforced on the Micro800 controller regardless of whether
the controller is password-protected or not. This means that only one
Connected Components Workbench software session is authorized at one
time and only an authorized client has exclusive access to the controller
application. This ensures that only one software session has exclusive access to
the Micro800 application-specific configuration.
Exclusive access is enforced on Micro800 firmware revision 1 and 2. When a
Connected Components Workbench software user connects to a Micro800
controller, the controller is given exclusive access to that controller.

(1) Ethernet configuration includes IP address, subnet mask, gateway, port speed/duplex and so on.
(2) Difference between Not Allowed and Rejected is that Not Allowed activities can only be done during offline while Rejected activities can be performed but do not take effect.
(3) Hard Run Mode can only be in Micro830, Micro850 and Micro870 controllers with Mode switch to RUN.
