FB_SMIPos2Read

FB_SMIPos2Read 1:

The function block FB_SMIPos2Read reads the fixed position Pos2 configured on the motor side. Pos2 can be changed with the function block FB_SMIPos2Write().

Inputs

VAR_INPUT
  bStart           : BOOL;
  dwAddr           : DWORD := 0;
  eAddrType        : E_SMIAddrType := eSMIAddrTypeAddress;
  dwAddrOption     : DWORD := 0;
  eCommandPriority : E_SMICommandPriority := eSMICommandPriorityMiddle;
END_VAR

Name	Type	Description
bStart	BOOL	The function block is activated and the command is sent by applying a positive edge to this input.
dwAddr	DWORD	Manufacturer code (0-15), address of a device (0-15), bit field (16 bits) for group addressing or slave ID (32-bit key ID). This input has no meaning if a broadcast is sent.
eAddrType	E_SMIAddrType	Specifies whether the input dwAddr is to be evaluated as manufacturer code, address of a device or for group addressing. Addressing via slave ID (eAddrType = eSMIAddrTypeSlaveId) is not permitted.
dwAddrOption	DWORD	Reserved for future extensions
eCommandPriority	E_SMICommandPriority	Priority (high, medium or low) with which the command is processed by the PLC library.

Inputs/outputs

VAR_IN_OUT
  stCommandBuffer : ST_SMICommandBuffer;
END_VAR

Name	Type	Description
stCommandBuffer	ST_SMICommandBuffer	Reference to the structure for communication (buffer) with the function block FB_KL6831KL6841Communication()

Outputs

VAR_OUTPUT
  bBusy      : BOOL;
  bError     : BOOL;
  udiErrorId : UDINT;
  wPosition  : WORD;
END_VAR

Name	Type	Description
bBusy	BOOL	This output is set as soon as the function block processes a command and remains active until the command has been processed.
bError	BOOL	This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in udiErrorId. The output is reset to FALSE by the reactivation of the function block via the input bStart.
udiErrorId	UDINT	Contains the command-specific error code of the most recently executed command. It is reset to 0 by the reactivation of the function block via the input bStart (see error codes).
wPosition	WORD	The read fixed position Pos1. The value 0 corresponds here to the upper end position and the value 65535 (0xFFFF) to the lower end position.

Requirements

Development Environment	PLC library to include
TwinCAT from v3.1.4020.14	Tc2_SMI from 3.3.5.0
