4.3 Mappings 905G to 905U I/O Modules
To transfer remote input signals to a 905G, or transfer a value to a remote output from a
905G, you set up “I/O mappings”. You enter mappings into the source unit, not the
destination unit. That is, you configure a mapping at the “input” module. If you want to
transfer an input signal at a 905U module to a 905G register, you enter a mapping at the
905U I/O module. If you want to transfer a 905G register to an output signal at a 905U
module, you enter a mapping at the 905G module.
To configure mappings, double-click on the module in the left-hand menu - the menu will
expand with selections for that module. Select “Mappings”.
Each mapping comprises only one I/O point.
“Block Mappings” provide more advanced
communications between 905G modules.
4.3.1 Mappings from Inputs at Remote 905U I/O Modules
Refer to the 905U I/O User Manual.
When mapping inputs to a 905G, you will be asked to select an I/O Register. Select the “…”
box beside the “At I/O Register” heading - this will allow you to select the I/O register
between 0 and 4299.
