Making a Client Request on a Port – ESDL

If your software component uses a ClientServer interface as Rport, you must define at least one runnable entity that acts as the client. You have to ensure that the client is triggered by an RTE event.

1. Open the SWC you want to edit.

2. For a client request without status inquiry, enter the following code:

   <CSinterface>.<operation>(<argument(s)>);

   • <CSinterface> is the ClientServer interface used as Rport
   • <operation> is the operation you want to call
   • <argument(s)> is a comma-separated list of the operation arguments

   Or

3. For a client request without status inquiry, proceed as follows.

   1. Enter the following code:

      <status_variable> = <CSinterface>.<operation>(<argument(s)>);

      • <status_variable> is the variable of type Std_ReturnType that holds the returned status
      • <CSinterface> is the ClientServer interface used as Rport
      • <operation> is the operation you want to call
      • <argument(s)> is a comma-separated list of the operation arguments

   2. Specify the status inquiry as follows:

      if (<status_variable> != RTE_E_OK)

      {

      ... // your statement or statement block

      }
