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 Beginning with RSLogix 5000 software, version 18, 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 upgrades via the ControlFLASH
utility.
Firmware Supervisor supports non-modular distributed I/O products that sit
directly on the network without an adapter, including CIP Safety I/O modules
on EtherNet/IP networks. CIP Safety I/O modules 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.
RSLogix 5000 software 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 firmware supervisor
updates. This does not include the controller firmware updates that occur
when the controller image is reloaded from the memory card.
