The battery condition is monitored by the module diagnostics every 24 hours. If the battery voltage is low or the battery is missing, a variable and the processor module Healthy status indicator goes red indicating a faulty battery, which needs replacing The following variables report a faulty battery: • Processor Module A NVRAM Battery Health • Processor Module B NVRAM Battery Health • Processor Module C NVRAM Battery Health The variable details are: • Direction: input to application from controller • Type: BOOLEAN • Values: • TRUE = the back-up battery in the 9110 processor module in the given slot is present and its voltage is within acceptable limits.Insert a new battery, orientate it the positive (+) terminal to the right. Trap the ribbon behind the new battery so it can be removed in the future and then push the battery into the holder. 4. Put the cover back and secure it with the cross head screw. 5. Push the Fault Reset button on the processor module. The processor Healthy status indicator will go green (applies if the module is part of a running system).

Replace a Faulty Processor Back-up Battery 

Use the following official Rockwell Automation battery or one of an equivalent specification. Part No and Description T9905: Polycarbon monofluoride Lithium Coin Battery, BR2032 (recommended type), 20 mm dia; Nominal voltage 3 V; Nominal capacity (mAh.) 190; Continuous standard load (mA.) 0.03; Operating temperature -30 °C to +80°C, supplied by Panasonic. The battery has a design life of 10 years when the processor module is continually powered; for processor modules that are un-powered, the design life is up to 6 months.If the battery is replaced when more than one processor module is installed then the processor clock will be updated automatically through synchronization. If you have previously set up SNTP when you set up your processor module then the clock will be reset to the current time automatically. If you have not set up SNTP it is recommended that you do so, as this will not only reset the processor clock but will also keep the time accurately during operation.

The following applies: 

• If the battery is replaced when only one processor module is installed and the processor module is not powered up and SNTP has not been set up, you must set the clock to the current time as soon as practicable. • The battery does not do any function while the processor module is powered and the application is running. The Processor’s Real Time Clock provides Date and Time data for SOE functions and also for the Processor diagnostic log entries. The specific functions that the battery maintains on complete loss of power are the following: • Real Time Clock – The battery provides power to the RTC chip itself.• Retained Variables – Data for retained variables is stored at the end of each application scan in a portion of RAM, backed by the battery. On restoration of power, the retained data is loaded back into the variables assigned as retained variables for use by the application scan. • Diagnostic logs – The processors diagnostic logs are stored in the portion of RAM backed by the battery
