Manually Map Discrete Data

Manually Map Discrete(rack) Data

1. On the 56RioCfgAdpt dialog box, right-click on the rack, and choose

Rack Map Discretes - Assign Manually.

2. On the Map Rack… Manually dialog box, from the CLX Block pull-

down, select the ControlLogix scheduled block and Data Offset within

the block.

3. Click OK to accept the mapping.

TIP

On monitored racks, inputs and outputs get mapped to

ControlLogix inputs, so be careful when mapping them so that

they don’t overlap.

Item Field CLX Data Type Rack Type Description

1 MonOut ClxInput data Monitored/

Active

Remote I/O scanner outputs are mapped to ControlLogix controller inputs. The 1756-

RIO module monitors output data sent by the scanner to the monitored/active rack. It

is reported in the ControlLogix controller as input data.

2 MonInp ClxInput data Monitored Remote I/O scanner inputs are mapped to ControlLogix controller inputs. The 1756-

RIO module monitors input data sent to the scanner by the monitored rack. It is

reported in the ControlLogix controller as input data.

3 ActInp ClxOutput data Active Remote I/O scanner inputs are mapped from the ControlLogix outputs. The

ControlLogix controller writes output tags to the 1756-RIO module, which sends the

data to the remote I/O scanner as input data.
