SimpleWriteValueInt

SimpleWriteValueInt (FB)

FUNCTION_BLOCK SimpleWriteValueInt

Use of type conversion operators (e.g. REAL_TO_INT) directly on the input 'InputValue'

In this constellation, compiler error messages of type C0032 are generated, a download is not possible. Remedy: Use an intermediate variable of the explicit type INT directly at the output of the type conversion operator. Connect the intermediate variable to the input 'InputValue'.

InOut:

Scope	Name	Type	Initial	Comment
Input	xEn	BOOL	TRUE	Enable / disable communication (TRUE = enable)
Input	byUnitId	BYTE	0	Address of the device
Input	InputValue	__SYSTEM.AnyType		Input variable (FC06, FC16) (USINT, UINT, UDINT, ULINT, SINT, INT, DINT, LINT)
Input	xUpdateSetp	BOOL	FALSE	Update setpoints (on every rising edge)
Input	xResError	BOOL	FALSE	Reinitialize the outputs 'eErrorCodeCom' and 'eErrorCodeDev' to the fault-free state (on every rising edge)
Inout	ModbusClient	ModbusClientBase		Client of the device
