Touble with Driver transform Class

[CyaNn]

Hello everyone,

I am developping a Serial/Modbus driver for WinCC and I experienced a little problem with Transform class.

I have created a TransformCoil specialized class to transform bit from Modbus to database and reciprocally

In fact, the method TransformCoil::toVar is never called, and the datapoint is never updated.
Where am I doing something wrong in my code:

Code: Select all

HWObject* SerialModbusHWService::storeToDB(QString address, PVSSchar *value) {
	HWObject *obj = new HWObject();
	obj->setDlen(sizeof(value));

	obj->setType((TransformationType)DriverTypes::COILS);
	obj->setAddress(address.toStdString().data());
	obj->setData(value);

	HWMapper* mapper = (HWMapper*)DrvManager::getHWMapperPtr();
	if ( mapper ) {
		HWObject* addrObj = mapper->findHWObject(obj);

		if ( addrObj ) {
			try {
				DrvManager::getSelfPtr()->toDp(obj, addrObj);
				// optional, to send it now !!!!
				//DrvManager::getSelfPtr()->sendData2Dp();
				DEBUG_DRV_USR2("Message stored to DB " getAddress()

I have these messages at the starting up of the driver:

OK! I have found my mistake.
I had hidden the para address direction config. So it was setted to output and not input by default.
Thuse, the driver could not write in the database.
Great ! I will continue.
