Estimate the ESM Support of
the WallClockTime The ESM provides support for the maintenance of the WallClockTime
attribute of the controller when power is not applied. Use this table to estimate
the hold-up time of the ESM, based on the temperature of the controller and
installed ESM.
Manage Firmware with
Firmware Supervisor You can use the Firmware Supervisor feature to manage firmware on
controllers. Firmware Supervisor lets controllers automatically update devices:
• Local and remote modules can be updated while in Program or Run
modes.
• Electronic keying must be configured for Exact Match.
• The firmware kit for the target device must reside on the controller’s
memory card.
• The device must support firmware updates via ControlFLASH
software.
Firmware Supervisor supports non-modular distributed I/O products that sit
directly on the network without an adapter, including safety I/O devices on
EtherNet/IP™ networks. Safety I/O devices on DeviceNet™ networks and
POINT Guard I/O™ modules are not yet supported.
Follow these steps to enable Firmware Supervisor.
1. On the Controller Properties dialog box, click the Nonvolatile Memory
tab.
2. Click Load/Store.
3. From the Automatic Firmware Updates pull-down menu, choose Enable
and Store Files to Image.
The Logix Designer application moves the firmware kits from your computer
to the controller memory card for Firmware Supervisor to use.

TIP If you disable Firmware Supervisor, you disable only the firmware
supervisor updates. This does not include the controller firmware
updates that occur when the controller image is reloaded from the
memory card.
