This function block can be used to read a 4-byte transmission sent from a POWERLINK station to a drive within the network.
Requirements for use
Function block name for SG3/SGC target systems MC_081BR_InitReceiveNetworkData
This function block can only be used for axes in a POWERLINK network.
Only data from a POWERLINK station that is being operated in the same network as the drive can be read.
It is only possible to access a bit offset that is a multiple of 32.
32 bits are always read starting at the specified bit offset.
PLCopen axis states in which the function block is permitted to be enabled
All PLCopen axis states, no effect on the PLCopen axis state

Description |
IN |
Axis |
UDINT |
Axis reference (receiver) |
IN |
BOOL |
Enables cyclic receipt of POWERLINK data on a rising edge |
|
IN |
NodeNumber |
USINT |
Node number of the POWERLINK station from which data should be received |
IN |
BitOffset |
UINT |
Bit offset of the POWERLINK data in the telegram from the transmitter from which point 32 bits are read |
IN |
DataType |
UINT |
Data type of the POWERLINK data ncPAR_TYP_DINT ncPAR_TYP_UDINT |
IN |
InterpolationMode |
USINT |
Interpolation mode for the received value mcIPL_OFF… 0 mcIPL_LINEAR … 1 mcIPL_QUADRATIC … 2 mcIPL_QUADRATIC_NO_OVERSHOOT … 4 Note: The default setting on the ACOPOS drive is mcIPL_LINEAR. |
IN |
ReceiveChannel |
USINT |
0 … Function block defines a receive channel 1 … 5 … Function block uses the specified receive channel Note: When a channel number is specified, the receive channel can be reconfigured for additional function block calls. If a different source is received via a previously configured receive channel, this can cause the value of "ReceiveParID" to jump. |
OUT |
Done |
BOOL |
Command executed Initialization completed, POWERLINK data read cyclically |
OUT |
Busy |
BOOL |
The function block is active and must continue to be called. |
OUT |
Error |
BOOL |
Error during execution |
OUT |
ErrorID |
UINT |
|
OUT |
ReceiveParID |
UINT |
ParID on the axis that can be used to further process the cyclically read value |
