8.14.4.12 GetPLCBool
Description: This method is replaced with the GetPLCBoolEx method and should not be used in new
applications. It is here only for backward compatibility reasons.
This method reads a Boolean value from the PLC output data area for ExtCom_API (see
Access to PLC data).
Return type : A RetCodeEnum value.
Syntax: object . GetPLCBool ( Address, Bit, Value )
Obj./Arg. Type Dir Description
object
Api
The Api object to operate on.
Address Integer In Specifies the offset in the PLC area of the Byte to read. Range
0
– 999.
Bit
Integer In Specifies which bit to read within the byte. Range 0
– 7 where
0 is the Least significant bit and 7 is the Most significant bit.
Value Boolean Out Returns the result. True if the read bit is 1, False otherwise.
8.14.4.13 SetPLCBool
Description: This method is replaced with the SetPLCBoolEx method and should not be used in new
applications. It is here only for backward compatibility reasons.
This method writes a Boolean value to the PLC input data area for ExtCom_API (see
Access to PLC data).
Return type : A RetCodeEnum value.
Syntax: object . SetPLCBool ( Address, Bit, Value )
Obj./Arg. Type Dir Description
object Api
The Api object to operate on.
Address Integer In Specifies the offset in the PLC area of the Byte to write. Range
0
– 999.
Bit Integer In Specifies which bit to write within the byte. Range 0
– 7 where
0 is the Least significant bit and 7 is the Most significant bit.
Value
Boolean In If True then the bit is set to 1. If False then it is set to 0.
