Status Data Types (1756-DNB, Major Revision 3)
The tables list and describe module-defined data types for the 1756-DNB module. The data types are listed below the way they are listed in the
Controller Tags
window from the Logix Designer
Data Monitor
. These tables include information for status as indicated by an "S".The data types associated with the input data types are sized according to the
Input Size
value on the General
tab. Each module-defined data type has minimum, maximum and intermediate sizes. Module-defined data type: AB:1756_DNB_Status_128Bytes:S:0 (S
ize of 32 selected)
Member name | Data type | Default display style | Definition |
ScanCounter | DINT | Binary | A counter that is incremented for each DeviceNet I/O Scan. |
DeviceFailureRegister | SINT[8] | Binary | One member for each DeviceNet node. 1 = device failed 0 = device working |
AutoverifyFailureRegister | SINT[8] | Binary | One member for each DeviceNet node. 1 = device I/O size does not match |
DeviceIdleRegister | SINT[8] | Binary | One member for each DeviceNet node. 1 = device is in idle state 0 = device is in run state |
ActiveNodeRegister | SINT[8] | Binary | One member for each DeviceNet node. 1 = DeviceNet node is online 0 = DeviceNet node is offline |
StatusDisplay | SINT[4] | Binary | DNB Front Panel display. |
ScannerAddress | SINT | Hex | DeviceNet node number of this DNB. |
ScannerStatus | SINT | Hex | DeviceNet status of this DNB. |
ScrollingDeviceAddress | SINT | Hex | The DeviceNet Address and status of nodes with errors. The data update once per second, scrolling through all nodes with errors. |
ScrollingDeviceStatus | SINT | Hex | Status of nodes with errors. The data update once per second, scrolling through all nodes with errors. |
DeviceStatus | SINT[64] | Hex | The status of each node on the DeviceNet, indexed by node number. |
