The OPEL Epsilon plugin for the KWP2000 component implements some special functions needed for GMLan on single wire CAN busses.
Remarks
The OPEL Epsilon plugin implements the high voltage wakeup sequence and optionally asynchronous tester present messages over the all nodes CAN id. The component adds four additional parameters to the KWP2000
component's parameter list to configure the special features and takes over control of some of the KWP2000 component's parameters.
It is necessary that the stack is complete but offline with a CAN component used as hardware driver for the OPEL Epsilon plugin to be loaded.
Parameters
-
EpsilonHVWUPID
-
The CAN id used to send the wakeup message.
-
EpsilonUseFunctionalTesterPresent
-
When this parameter is set to 0 the plugin does not replace the normal tester present sequence of the KWP2000 component - tester present messages are then sent over the physical channel. When this parameter is
set to 1 the plugin disables the KWP2000 component's tester present function and generates tester present messages which it sends over the functional channel asynchronous to the regular communication. In
this case it uses the KWP2000 component's parameter TesterPresentInterval to determine the interval time.
-
EpsilonAllNodesCANID
-
This parameter sets the can id used for the functional channel when EpsilonUseFunctionalTesterPresent is set to 1. This parameter has no meaning when EpsilonUseFunctionalTesterPresent is set to 0.
-
EpsilonAllNodesECUID
-
Sets the ECU id used for sending tester present messages when EpsilonUseFunctionalTesterPresent is set to 1. This parameter has no meaning when EpsilonUseFunctionalTesterPresent is set to 0.
