int __stdcall SM_SetSoftwareAddress ( SM_HANDLE  handle, int  slaveID  ) Configure's a Sealevel I/O module's software selectable Modbus slave ID (Modbus devices only). Parameters [in] handle Valid handle returned by SM_Open(). [in] slaveID Desired slave ID of the Modbus compliant Sealevel I/O module. Return values 0 Successful completion. -1 Invalid SeaMAX handle. -2 Connection is not established. Check the provided Connection object state. -3 Error writing to Modbus device. -4 Failed to perform implicit "Get Module Configuration (0x45)" This method attempts to set the software selectable address (slave ID) of a Sealevel I/O module, whose side rotary switch is set to the "0" position. By default, setting the side switch to zero will result in a Modbus slave ID address of 247. The "Set Software Slave ID" Modbus function requires a security key byte, received by performing a "Get Module Configuration (0x45)". If the security key has not previously been explicitly requested , the SetSoftwareAddress() method will automatically perform the "Get Module Configuration" function prior to executing the "Set Software Slave ID" Note If the side rotary switch is not in the zero position, this Modbus function will fail.
