FP_ETHERNETIP_GET_STATE_TABLE_ALL

Read the EtherNet/IP communication state on all nodes

This FP instruction reads the parameter information or status information on all registered nodes and stores it in the output variable of the type FP_ETHERNETIP_STATE_TABLE_ALL_DUT.

Parameters

Output

d_dutStateTableAll (FP_ETHERNETIP_STATE_TABLE_ALL_DUT): Destination to which the data is written

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if the read area is outside the permissible range
if the instruction is executed in an interrupt program

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

if the read area is outside the permissible range
if the instruction is executed in an interrupt program

Example
