  • Page 76 02/02 AWB27-1300-GB Telecontrol function blocks Error code Meaning Service not enabled The service 30 performed is rejected by the partner station because the “stationtype” function block input of the partner station has been assigned 0 value. Frame sequence bit error The frame sequence bit is used to prevent communication loss or message duplication.

    02/02 AWB27-1300-GB 6 Data Transmission Example The following example shows the PS416 (active station) dialling a PS4-200 (passive station) via modem and dial-up line. The PS416 executes service 17: Send/read fixed frame length RAM data The input and output signals are shown on the relevant function (parameter) function blocks for this sequence.
  • Page 79 02/02 AWB27-1300-GB Data Transmission Example When the program is started or the function block reset, the status display shows the input and output signals in their basic setting. After the first service has been executed, the signals have the following form. Key to figure 18: dial: a Inputs...

    02/02 AWB27-1300-GB Glossary Application module Application modules are programs or parts of a program for the PLC or PC that support a function or completely execute a function in an application. They provide ready-made solutions for different applications. Asymmetrical configuration Configurations of telecontrol stations consisting of primary and secondary stations are referred to as asymmetrical configurations.
