How to resolve module image assignment error on Allen-Bradley Control Unit?
If your Allen-Bradley Control Unit indicates that a module in a slot has only part of its image assigned to the 1747-ASB image (1/2-slot addressing and discrete mode only), change the 1747-ASB module image size (SW2-5,6,7,8) or specialty mode (SW3-9).
What to do if Allen-Bradley 1747-ASB Control Unit shows configuration store fault?
If your Allen-Bradley Control Unit shows a 'Configuration Store Fault (EEPROM failed write verification)' error, cycle the power to reset the 1747-ASB module. If the issue continues, replace the 1747-ASB module.
What to do if Allen-Bradley 1747-ASB displays I/O runtime fault?
If your Allen-Bradley Control Unit displays 'I/O Runtime Fault (Error, Location)', check the I/O module in the specified slot. Cycle the power to both the 1747-ASB module and the I/O module. If the problem persists, replace the I/O module.
What to do if Allen-Bradley Control Unit shows Powerup Self Test Error?
If your Allen-Bradley Control Unit displays 'Powerup Self Test Error (normal operating mode)', cycle the power to reset the 1747-ASB module. If the problem continues, replace the 1747-ASB module.
What to do if Allen-Bradley Control Unit has Runtime RAM Fault?
If your Allen-Bradley Control Unit shows a 'Runtime RAM Fault', cycle the power to reset the 1747-ASB module. If the problem continues, replace the 1747-ASB module.
What to do if Allen-Bradley Control Unit shows module is in test mode?
If your Allen-Bradley Control Unit shows 'Module is in test mode', check jumper pins on the bottom of the 1747-ASB module to ensure they are not connected to anything.
How to resolve undefined addressing mode on Allen-Bradley 1747-ASB Control Unit?
To resolve 'Undefined Addressing Mode' error on your Allen-Bradley Control Unit, check addressing mode selection (SW3-5,6).
How to resolve invalid baud rate on Allen-Bradley 1747-ASB?
To resolve 'Invalid Baud Rate' on your Allen-Bradley Control Unit, check baud rate selection (SW2-1,2).
How to fix last address exceeded error on Allen-Bradley Control Unit?
To address the 'Last Address Exceeded' error on your Allen-Bradley Control Unit, check the starting logical rack number (SW1-1,2,3,4,5,6), starting logical group number (SW1-7,8), and image size selection (SW2-5,6,7,8).
How to resolve I/O configuration mismatch on Allen-Bradley 1747-ASB?
If your Allen-Bradley Control Unit displays 'I/O Configuration Mismatch and Location' due to a problem with a specific slot, correct the I/O module configuration problem or change to Save Mode.
