FB_Read_IuM_EL6631_0010

The function block FB_Read_IuM_EL6631_0010 reads I&M1, I&M2, I&M3 and I&M4 (Identification & Maintenance) data from a PROFINET device via EtherCAT as a string. The I&M0 data is read for a PROFINET device with EtherCAT via CoE (CAN over EtherCAT).

Inputs

VAR_INPUT
  bRead             : BOOL;;
  NETID             : T_AmsNetId;
  PORT              : T_AmsPort;
  iNumber           : INT:=0;
END_VAR

Name	Type	Description
bRead	BOOL	A positive edge at this input enables the function block and the I&M data is read from the PROFINET device.
NETID	T_AmsNetId	AMS Net ID of the controller
PORT	T-AmsPort	Port via which the controller communicates with the device (port = Device ID + 1000hex).
iNumber	INT	Two PROFINET devices can be mapped with one terminal. iNumber ("0" or "1") is used to select the device for which the I&M data is to be read.

Outputs

END_VAR

Name	Type	Description
bBusy	BOOL	When the function block is enabled, this output is set and remains set until a feedback is received. While Busy = TRUE, no new command will be accepted at the inputs.
bError	BOOL	If an error occurs during the transmission of the command, this output is set after the bBusy output is reset.
iErrorID	UDINT	Returns an ADS error number if bError output is set.
st_IM_TagFunction	STRING	Label read for function of the device. I&M1
st_IM_Taglocation	STRING	Label read for the installation location of the device. I&M1
st_IM_Date	STRING	Returns the device installation date in the format. I&M2
st_IM_Descriptor	STRING	Returns the vendor description stored for the device. I&M3
st_IM_Signature	STRING	Returns the vendor signature stored for the device. I&M4
