What 1756-Dnb Module Data Tables Are And What They Do; The Scanner Configuration Table (Sct) - Rockwell Automation Allen-Bradley ControlLogix DeviceNet 1756-DNB User Manual

What 1756-DNB Module
Data Tables Are and What
They Do
To manage the flow of data between your controller and the network
devices, the 1756-DNB module uses the following data tables.
• 1756-DNB Module Configuration Table
• Scanlist Table
• Device Input Data Table
• Device Output Data Table
• Device Idle Table
• Device Failure Table
You can configure two of these data tables through RSNetWorx
software. These two tables are stored in the 1756-DNB module's
non-volatile memory and used to construct all other data tables:
• Scanner Configuration Table (SCT)
• Scanlist Table (SLT)

The Scanner Configuration Table (SCT)

The SCT controls basic information your 1756-DNB module needs to
function on your DeviceNet network. It tells your 1756-DNB module:
• if it can transmit and receive input and output data
• how long it waits after each scan before it scans the devices
again
• when to send out its poll messages
