Overview
Configured for backup power and retained PLC data support in VersaMax Micro systems, the GE Fanuc Emerson IC200ACC403 (IC200ACC403 battery) provides direct electrical backup through a lithium coil cell assembly installed in the PLC battery holder. The battery supports retained data functions during controller power-down conditions and reports its battery state through the PLC fault table or Status Bits %SA011 and %SA014.

VersaMax PLC Backup and Firmware Compatibility
The GE Fanuc Emerson IC200ACC403 operates as a dedicated backup power component rather than an I/O or communication module. It connects through the designated battery holder in the VersaMax Micro PLC and supplies backup energy to supported retained data functions when external controller power is unavailable.
In addition, the PLC monitors battery condition and can report battery-related status through the fault table. Status Bits %SA011 and %SA014 also provide controller-level battery state indication. Therefore, maintenance personnel can check battery condition through PLC diagnostics without treating the battery as a separate network device.
The IC200ACC403 does not perform backplane bus communication or deterministic network processing. Instead, its function remains limited to the electrical backup circuit and associated controller data retention functions.
Frequently Asked Questions
Q: Where is the IC200ACC403 installed?
A: The IC200ACC403 installs in the designated battery holder of a VersaMax Micro PLC.
Q: How does the PLC report the battery state?
A: The controller can report battery status through the PLC fault table or through Status Bits %SA011 and %SA014.
Q: What backup performance is specified for the IC200ACC403?
A: The battery provides a minimum backup time of 4 months at 55 deg C when the associated PLC is powered down.
Field Installation Guidelines
Disconnect or isolate controller power according to the applicable system maintenance procedure before accessing the battery holder.
Install the IC200ACC403 only in the designated VersaMax Micro PLC battery location. Route the included wire leads without pinching, excessive bending, or contact with sharp cabinet edges.
Observe battery polarity and connector orientation during installation. Do not modify the battery leads or connect the battery directly to external field wiring.
After installation, restore controller power and check the PLC fault table and applicable status bits to verify battery condition. Record the replacement date to support preventive maintenance scheduling based on the specified storage and installation life.
