Valid for: CANoe DE • CANoe4SW DE

​
Function Syntax

  • gmLanSetPID(gmLanMessage msg, long v);
  • gmLanSetSourceId(gmLanMessage msg, long v);
  • gmLanSetPrio(gmLanMessage msg, long v);
  • gmLanGetPID(gmLanMessage msg);
  • gmLanGetSourceId(gmLanMessage msg);
  • gmLanGetPrio(gmLanMessage msg);

​
Description

  • gmLanSetPID sets the parameter ID of the message.
  • gmLanSetSourceId sets the source address of the message.
  • gmLanSetPrio sets the priority of the message.
  • gmLanGetPID gets the parameter ID of the message.
  • gmLanGetSourceId gets the source address of the message.
  • gmLanGetPrio gets the priority of the message.

​
Parameters

  • msg: Message
  • v: Parameter ID, source address or priority

​
Return Values

  • gmLanSetPID, gmLanSetSourceId, gmLanSetPrio: —
  • gmLanGetPID, gmLanGetSourceId, gmLanGetPrio: Parameter ID, source address or priority

​
Example

A GMLAN message is modified and sent with output(msg).
The parameter ID is set with selector gm_pid. 
gmLanMessage * msg1 ={SA =0x44, PRIO=  0x7,  gm_pid=0x11};
gmLanSetSourceId(msg1,0x55);
gmLanSetPID(msg1,0x11);
gmLanSetPrio(msg1,0x5);

output(msg1);

write("pid: 0x%x, source: 0x%x, prio:  x%x",gmLanGetPID(msg1),gmLanGetSourceId(msg1),gmLanGetPrio(msg1));
Priority and source address are copied from Battery_Voltage message to the new message msg: 
on gmlanmessage  Battery_Voltage
{
  gmlanmessage Battery_Voltage msg;
  msg = this;  // SA and PRIO are not copied
  gmLanSetSourceId(msg, gmLanGetSourceId(this));
  // Copy  source address from Battery_Voltage to msg
  gmLanSetPrio(msg,  gmLanGetPrio(this));
  // Copy priority from Battery_Voltage to msg
  ...
}
