FB_SMISyn

FB_SMISyn 1:

The function block FB_SMISyn queries the manufacturer code and the drive type.

FB_SMISyn 2: 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.

FB_SMISyn 3: 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()

FB_SMISyn 4: Outputs

VAR_OUTPUT
  bBusy            : BOOL;
  bError           : BOOL;
  udiErrorId       : UDINT;
  byManufactorCode : BYTE;
  byDriveType      : BYTE;
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).

byManufactorCode

BYTE

The manufacturer code (1-14)

byDriveType

BYTE

The drive type (0-15). The meaning is manufacturer-specific.
