CPU001-AA 1.00 Initial Product Release
This release replaces firmware version 2.10 through 2,34. The following
CPUs can be upgraded to the new firmware version:
▪ CPU001 versions CC and later
▪ CPU002: all versions
The following CPUs cannot be upgraded. To use the new features of this
release, new CPU hardware must be purchased:
▪ CPU001 versions AA, AB, BA, BB, BC, BD
If you need to determine the current firmware version of a CPU, see the
steps below:
▪ With Machine Edition Logic Developer, go online to the CPU,
then select Target > Online Commands > Show Status. The
Device Information Software Revision shows the current firmware
revision level.
▪ With a VersaPro or Control programmer, attach the CPU. Under
the PLC menu (VersaPro) or the Comm menu (Control), select
the Memory tab on the Status Information dialog.
A firmware upgrade is optional. Upgrading is recommended for
applications that use PID function blocks or serial communications. An
upgrade can be ordered from the factory (For CPU001: 44A747796-G09.
For CPU002: 44A751403-G06), or downloaded from GEFanuc.com. The
firmware resides in FLASH memory, and is upgraded by serial download
from a Windows PC via CPU port 1. Port 2 cannot be used for a
firmware upgrade.
