Understanding Adjacent Modules

These registers only contain meaningful data if the ConveyLinx connections between upstream and/or downstream modules are preserved when placing the local module into PLC I/O mode from within EasyRoll. If connections are cleared in EasyRoll, these registers will not contain any pertinent data and will not be updated by adjacent modules. Learn about clearing connections.
