Configure the Module in a GuardLogix Controller System Chapter 5
Save and Download the 
Module Configuration
After you configure a module, it is recommended that you save and download the 
configuration.
If, after downloading the program, the MS and NS status indicators on the 
POINT Guard I/O module are not both solid green, a loss of ownership 
potentially occurred. A yellow yield icon in the project tree also indicates a loss of 
ownership. For more information, see Chapter
8.
Update POINT Guard I/O 
Modules
In addition, the 1734-IE4S safety analog input module requires field power to be 
applied while updating the firmware of the module. If a ControlFLASH update 
fails, check the ControlFLASH log by clicking View Log on the Update Status 
dialog box.
If the last message is ‘[FAILURE] Update: Error #11001: Unknown General 
Status error code received. GS = 0xD0, ES = 0x0001,’ verify that field power is 
connected to the module and restart the download. 
When you use ControlFLASH™ software to update a module, the software stops 
a running safety I/O connection. You must inhibit I/O connections before 
updating a POINT Guard I/O module.
The module receives it's field power from the 24V DC connection to the power 
supply feeding it, for example a 1734-AENT, 1734-FPD, or 1734-EP24DC 
module. Make sure that 24V DC power is connected to these modules before 
performing a flash update of the 1734-IE4S.
