_DriverCommon (General driver)

DP element	Type	Description
AD.DPMatch	Dyn. DP Identifier	Diagnostics for peripheral addresses: If a wildcard string is sent to the HWMask element, the driver returns a list of all data point elements in this element that are configured to a matching peripheral address. The expression * therefore returns all data point elements that have a peripheral address in the active driver.
AD.HWMask	string	Diagnostics for peripheral addresses: A wildcard string is sent to this element: all peripheral addresses matching it should be found.
DC	bool	Internal element for redundancy monitoring. If this bit is set, the driver cannot send any data to the periphery. This element won't be set in the redundant system. This means that no information can be derived about whether the driver is sending commands. Used in combination with the MS element.
HW.HWMask	string	If a wildcard string is sent to this element, all matching periphery adresses are returned.
HW.HWMatch	dyn_string	Returns all periphery addresses matching the wildcard string defined at HW.HWMask.
EM	uint	Error mode of the driver. If this value is greater than 0, the general driver's error reporting is activated.
GQ	uint	General query. If this element is set, a general query is made for all drivers. For the OPC client, this means a refresh call for all groups in all servers to which the client is connected.
PE	float	This value specifies by how much the planned polling time may deviate from the actual execution time before the job is canceled and executed at the next scheduled time. This element is used for debugging purposes and is not intended for changes by the user..
MS	bool	This DPE allows to set the driver status via the DC data point element. FALSE: Driver derives his Redu status from messages of the Event Manager. TRUE: Driver derives his status from the DC data point element. Default value is FALSE.
PM	bool	Polling can be activated or deactivated with this bit. The bit is not relevant for drivers that do not poll the inputs cyclically.
SM	uint	This value determines the driver's smoothing mode. Three levels are distinguished: 0 always smooth (normal status) 1 always smooth except for the general query 2 never smooth (i.e. let everything pass) Note that when you update a project or create a new project, the value of the datapoint is set to 1, meaning that the values are always smoothed except for the general query.
SQ	Dp Identifier	If a valid identifier is passed to this element, the corresponding element is retrieved from the periphery in a single query. Of course, this is only possible if the given element has a periphery Config and is open as an input.
IGQ	string	The data point element IGQ in the general driver sends set values or commands from WinCC OA to the peripheral device. In fact, the values are sent to all DPs whose peripheral address matches the mask specified as a value in the IGQ data point element. Example: Enter the following strings as an original value of the DP: "" ... sends the set values for all DPs. "1_" ... sends the set values for all DPs whose peripheral address start with "1_". Several masks can be separated by ";".
DT	string	This element defines the type of the driver, for example, RK512 for driver RK512, PRFMS for driver Profibus, SIM for driver Simulator, ...
OV	bool	This element signals the overloading of a driver. In addition, this element has an alert handling and is displayed in the alert screen if the driver generates an overload (i.e. the driver generates data faster than it can be processed in the system).
AL.AckDps	dyn_dpid	The data point elements AckDps and AckData allow to acknowledge alerts via the driver. AckDps contains the data point elements of the alerts to be acknowledged. There must be an alert time for each data point element.
AL.AckData	dyn_string	The data point elements AckDps and AckData allow to acknowledge alerts via the driver. AckData contains the alert times of the alerts to be acknowledged. The alert time must be specified in the following format: "<time stamp> \| <counter>" Example: "2016.04.12 16:14:22.710 \| 16"
AL.AClasses	dyn_string	If the driver states an alert class when triggering an alert, the respective alert class must be defined here. There will be an error if the driver tries to state an alert class which is not known to the ComDrv.

AD.DPMatch

Dyn. DP Identifier

Diagnostics for peripheral addresses: If a wildcard string is sent to the HWMask element, the driver returns a list of all data point elements in this element that are configured to a matching peripheral address. The expression * therefore returns all data point elements that have a peripheral address in the active driver.

AD.HWMask

string

Diagnostics for peripheral addresses: A wildcard string is sent to this element: all peripheral addresses matching it should be found.

DC

bool

Internal element for redundancy monitoring. If this bit is set, the driver cannot send any data to the periphery.

This element won't be set in the redundant system. This means that no information can be derived about whether the driver is sending commands.

Used in combination with the MS element.

HW.HWMask

string

If a wildcard string is sent to this element, all matching periphery adresses are returned.

HW.HWMatch

dyn_string

Returns all periphery addresses matching the wildcard string defined at HW.HWMask.

EM

uint

Error mode of the driver. If this value is greater than 0, the general driver's error reporting is activated.

GQ

uint

General query. If this element is set, a general query is made for all drivers. For the OPC client, this means a refresh call for all groups in all servers to which the client is connected.

PE

float

This value specifies by how much the planned polling time may deviate from the actual execution time before the job is canceled and executed at the next scheduled time. This element is used for debugging purposes and is not intended for changes by the user..

MS

bool

This DPE allows to set the driver status via the DC data point element. FALSE: Driver derives his Redu status from messages of the Event Manager. TRUE: Driver derives his status from the DC data point element. Default value is FALSE.

PM

bool

Polling can be activated or deactivated with this bit. The bit is not relevant for drivers that do not poll the inputs cyclically.

SM

uint

This value determines the driver's smoothing mode. Three levels are distinguished:

0 always smooth (normal status)

1 always smooth except for the general query

2 never smooth (i.e. let everything pass)

Note that when you update a project or create a new project, the value of the datapoint is set to 1, meaning that the values are always smoothed except for the general query.

SQ

Dp Identifier

If a valid identifier is passed to this element, the corresponding element is retrieved from the periphery in a single query. Of course, this is only possible if the given element has a periphery Config and is open as an input.

IGQ

string

The data point element IGQ in the general driver sends set values or commands from WinCC OA to the peripheral device. In fact, the values are sent to all DPs whose peripheral address matches the mask specified as a value in the IGQ data point element.

Example: Enter the following strings as an original value of the DP:

"*" ... sends the set values for all DPs.

"1_*" ... sends the set values for all DPs whose peripheral address start with "1_". Several masks can be separated by ";".

DT

string

This element defines the type of the driver, for example, RK512 for driver RK512, PRFMS for driver Profibus, SIM for driver Simulator, ...

OV

bool

This element signals the overloading of a driver. In addition, this element has an alert handling and is displayed in the alert screen if the driver generates an overload (i.e. the driver generates data faster than it can be processed in the system).

AL.AckDps

dyn_dpid

The data point elements AckDps and AckData allow to acknowledge alerts via the driver.

AckDps contains the data point elements of the alerts to be acknowledged. There must be an alert time for each data point element.

AL.AckData

dyn_string

The data point elements AckDps and AckData allow to acknowledge alerts via the driver.

AckData contains the alert times of the alerts to be acknowledged. The alert time must be specified in the following format: "<time stamp> | <counter>"

Example: "2016.04.12 16:14:22.710 | 16"

AL.AClasses

dyn_string

If the driver states an alert class when triggering an alert, the respective alert class must be defined here. There will be an error if the driver tries to state an alert class which is not known to the ComDrv.
