Operating modes

WS devices can be operated in the following modes:• Real-time mode• Data Logging / File Transfer mode

Real time mode

CAN messages, are received by the device and sent via the Danfoss Web portal server to the remote PC.On this computer there may be an analysis software which can handle the CAN messages. A bi-directional data transfer is possible. When higher layer protocols are used, a special firmware andsoftware adaptation may be necessary due to the delay times caused by the GSM/3G network.Depending on the device features, you can transmit data from the GNSS receiver and the input/outputfunctions and pass them on via the CAN bus. You can save all data to be transmitted to an internal,nonvolatile memory and transmit them sequentially. Data is transmitted constantly and can be evaluatedin close to real-time. This function requires a permanent link between the device and the user softwarevia the DTS server. In the absence of a link to the server, data can be saved to a micro SD memory cardand transmitted at a later time (this function requires that a micro SD memory card is inserted and thefunction is enabled ).

WS System Tools work correctly only when connected to CAN1 of WS devices. When connected remotelyto WS devices with PLUS+1 Service Tool it is only possible to see the ECU connected on CAN1, not CAN2.

Data logging / File-transfer mode

In this operation mode the WS unit logs specific CAN messages, GNSS position data and internal variablesaccording to its configuration and sends them in a special format to the DTS server. The WS devices havean internal non-volatile memory which allows to store the files in case of a GSM/UMTS outage. When theconnection is recovered the files are sent to the server automatically. You can also save the data to aninserted micro SD memory card. You can read off the data saved on the micro SD memory card using theUSB interface.

Wireless solutions

WS503/WS503-BP interfaces transmit data available on a CAN bus via GSM/UMTS telecommunicationservices. In addition to data transmission via GSM/GPRS, the WS devices use the EDGE, 3G and HSPAstandards to reduce data transmission latency and to improve data transfer rate.

Beyond the GSM/UMTS functionality, these services allow for communication with web servers at higherdata rates. The communication is based on the TCP/IP protocol. Using these services requires aconnection to a specific Danfoss server.


Device functions


Integrated into the device is a SIM card slot and the network operator SIM card, mini SIM 15x25mm orother SIM card with adapters.

The SIM card remains internally in the housing.

Inserting the SIM card is only possible by unscrewing the housing. Furthermore, an embedded SIM isprovided which can be used on a SIM-card switching. It can only ever be either posted at the same timethe replaceable SIM card or embedded SIM in the mobile network. Switching between two SIM cardrequires a restart the whole device.

The functionality depending on the ambient temperature can be assured for the maximum transfer ratein the HSPA standard only between -38 ° C to 55 ° C.

For the frequency band cover a GSM quad-band and UMTS band six-module is used, which covers allGSM frequency bands and the main UMTS frequency bands worldwide.

Local Geofence in the WS device

The WS503/WS503-BP mobile features local Geofence monitoring. This allows you to monitor whetherthe device is located inside or outside a pre-defined fence and when the device crossed the fence. Thereare three ways of defining the fence:• Define center and radius of a circle. The center of the circle is defined as a fixed point.• Define center and radius of a circle. The current position at the time of enabling is used for the center

of the circle.• Two opposite points are defined for a rectangle

The variables belong to the object dictionary group DEVICE VARIABLES.

The default type of variables in the internal geo fence section is J1939.

Accessories

GEOFENCE - MODE 0 = Geofence disabled1 = Geofence enabled, circle center and defined radius.2 = Geofence enabled, circle center, current position, anddefined radius3 = Geofence enabled, rectangle

GEOFENCE – COORDINATE 1 - LONGITUDE Longitude for center of the circle or first corner of therectangle.

GEOFENCE – COORDINATE 1 - LATITUDE Latitude for center of the circle or first corner of therectangle.

GEOFENCE – COORDINATE 2 - LONGITUDE / RADIUS Circle radius in meters or longitude for the second cornerof the rectangle.

GEOFENCE – COORDINATE 1 - LATITUDE Latitude for the second corner of the rectangle

With the Geofence status, you can trigger an event internally. The Geofence status is updated every 2seconds. Every time the Geofence status changes, the time is written to a variable. The variables belongto the object dictionary group DEVICE VARIABLES

Accessories

GEOFENCE STATUS 00 = device is outside the fence01 = device is inside the fenceFF = status unknown (e.g. because no position data isavailable)
