DeviceNet Plug-in – 2080-DNET20 Appendix 5
Sample Code: RA_DNET_NODE_STATUS
RA_DNET_LDX_DISCRETE
This UDFB is used for I/O data exchange with discrete CompactBlock I/O.
RA_DNET_NODE_STATUS: Input and Output Parameters
Variable Name Type Data Type Description
FBEN INPUT BOOL Function block enable input.
TRUE to enable the function.
SlotID INPUT UINT Plug-in slot number (1…5)
NodeID INPUT USINT Slave node address.
FBENO OUTPUT BOOL Function block enable output.
TRUE upon exit.
Status OUTPUT USINT Scanner fault status.
0: No errors.
Error OUTPUT STRING Description of the node status error.
RA_DNET_LDX_DISCRETE: Input and Output Parameters
Variable Name Type Data Type Description
FBEN INPUT BOOL Function block enable input.
TRUE to enable the function block.
SlotID INPUT UINT Plug-in slot number (1…5)
NodeID INPUT USINT Node address of the digital Compact I/O slave node.
Module1 INPUT STRING Base module I/O configuration.
INPUT X OUTPUT Channels
For example: 16X0 (16 input / 0 output is physically
present as base module)
