Updating the Firmware 
By using ControlFlash™ software, the 8-channel module firmware can be 
upgraded or downgraded between major revisions 1 and 2. A 6-channel 
module can be updated if any owning connection was in Run mode.
An 8-channel input module (catalog number 1756-IF8I or 1756-IRT8I) in 
Emulation mode can only be updated if there are no owner connections to the 
module. If necessary, temporarily inhibit the connection or move the module 
to an unused slot when you update an 8-channel input module with a 6-
channel module owner connection. 
An 8-channel output module (catalog number 1756-OF8I) in Emulation 
mode can only be updated if the owner connection to the module is in 
Program mode or if there is no owner connection. If necessary, temporarily 
inhibit the connection or move the module to an unused slot when you update 
an 8-channel input module with a 6-channel module owner connection.
