	int regAddr, 
	short andMask, 
	short orMask
)

Parameters

slaveAddr: Type: SystemInt32
Modbus address of slave device or unit identifier (Range: 1 - 255)
regAddr: Type: SystemInt32
Register address (Range: 1 - 65536)
andMask: Type: SystemInt16
Mask to be applied as a logic AND to the register
orMask: Type: SystemInt16
Mask to be applied as a logic OR to the register

Type: Int32
BusProtocolErrors.FTALK_SUCCESS on success or error code. See BusProtocolErrors for possible error codes.
