0xF230 The maximum number of expansion I/O modules
has been exceeded.
Perform the following:
1. Power off the controller.
2. Check that the number of expansion I/O modules is not more than four.
3. Power on the controller.
0xF250 There is a non-recoverable error and the
expansion I/O module(s) could not be detected.
Perform the following:
• Cycle power to your Micro800 controller.
If the error persists, contact your local Rockwell Automation technical support
representative. For contact information, see

.
0xF26z
(z indicates the
slot number of the
expansion I/O. If
z=0, then the slot
number cannot be
identified.)
An expansion I/O master fault is detected on the
system.
Perform the following:
• Cycle power to your Micro800 controller.
If the error persists, contact your local Rockwell Automation technical support
representative. For contact information, see
http://support.rockwellautomation.com/MySupport.asp
.
0xF27z
(z indicates the
slot number of the
expansion I/O. If
z=0, then the slot
number cannot be
identified.)
A non-recoverable communication fault has
occurred on the expansion I/O module.
Perform one of the following:
• Cycle power to the Micro800 controller, or
• Replace the slot number z module.
If the error persists, contact your local Rockwell Automation technical support
representative. For contact information, see

.
0xF28z
(z indicates the
slot number of the
expansion I/O. If
z=0, then the slot
number cannot be
identified.)
Expansion I/O baudrate error. Perform one of the following:
• Cycle power to the Micro800 controller, or
• Replace the slot number z module.
If the error persists, contact your local Rockwell Automation technical support
representative. For contact information, see
http://support.rockwellautomation.com/MySupport.asp
.
0xF29z
(z indicates the
slot number of the
expansion I/O. If
z=0, then the slot
number cannot be
identified.)
A module fault is detected on your expansion I/O
module.
Perform one of the following:
• Cycle power the Micro800 controller, or
• Replace the slot number z module.
If the error persists, contact your local Rockwell Automation technical support
representative. For contact information, see
http://support.rockwellautomation.com/MySupport.asp
.
0xF2Az
(z indicates the
slot number of the
expansion I/O. If
z=0, then the slot
number cannot be
identified.)
Expansion I/O power failure Perform one of the following:
• Cycle power the Micro800 controller, or
• Replace the slot number z module.
If the error persists, contact your local Rockwell Automation technical support
representative. For contact information, see
http://support.rockwellautomation.com/MySupport.asp
.
0xF2Bz
(z indicates the
slot number of the
expansion I/O. If
z=0, then the slot
number cannot be
identified.)
Expansion I/O configuration fault. Perform one of the following:
• Correct the expansion IO module configuration in the user program to match
that of the actual hardware configuration.
• Check the expansion I/O module operation and condition.
• Cycle power to the Micro800 controller.
• Replace the expansion I/O module.
