call:         	- ANALOG board: Specifies witch board in target data is sent to. 
                  Hilscher hardware supports up to 4 cards pr. target. Typically 0
                - ANALOG Node: Specifies witch node on the can bus the data is for. CanOpen support up to 127 nodes.
                - ANALOG Index: Index in node to receive the data.
                - ANALOG Subindex: subindex for the specific index, to receive the data.
                - ANALOG Datasize: Length of data field in the specific subindex, in bytes. possible values: 1,2 and 4.
                - ANALOG Data: Data to sendt to node.
                - ANALOG Timeout: Max time to wait for function in milliseconds. 
                  Timeout is used at least twice in this function. Max 100ms.

return:        - Boolean Ok: returns true if write is successful, false if an error occurred.

example:       - write data : 1234 to index 24743 subindex 0 in node 2, 
                  connected to board 0, the command would look like the 
                  following: return := WSDO(0,2,24743,0,4,1234,100) all values 
                  are in decimal.
                  If the function returns ok, the data is passed on to the node, 
                  and the node has responded with a non error answer.
