Touch / Operator -- Operation and maintenance -- Diagnosing errors Why are fonts and objects shown shifted on a WinCC flexible PC Runtime system or operator ? Message 632 when selecting the message level via softkey in OP3 OP7 / OP17 hang during startup and issue the message: Flash full. Configuration to OP7/17 DP12 -> Display of Version Number and Start Code No start-up of the OP7-DP after power Off/On Error message on WinCE : "pData.fwd not found" in ProTool V6.0 Damage of the MPI/DP interface (RS485) on the The Operator sporadically displays the error message: "$044 Transfer error ... " The Operator sporadically displays the error message: "$044 Transfer error ... " QUESTION:   What is the meaning of the error message "$044 Transfer error ... " that is displayed sporadically on the OP? ANSWER:   During communication with the controller the error message "$044 Transfer error ... " that is displayed sporadically on the OP. This message is output when the connection between the OP and the controller is defective. Possible causes can be faults in the transfer segment (bus faults on MPI/ PROFIBUS) or also wrongly set interface parameters on the Operator or on the controller. Please check the following points to clear this fault:

Connection of the OP to the controller To ensure correct connection of the OP to the controller we recommend configuring using the ProTool option "STEP 7 integrated". This means that your ProTool configuration is a component of the STEP 7 project. If you connect the OP correctly to the available MPI or PROFIBUS subnetwork of the U (ProTool: Entry "Controller" see Fig. 1), the OP is inserted as bus node and taken into in the calculation of the bus times in NetPro (see Fig. 2).

Fig. 2: Bus nodes in NetPro Note: If it is not possible to integrate the OP project in STEP 7, you can change the bus times as " defined" (see Properties of PROFIBUS). In this case you increase the target rotation time (TRT) so that the U can communicate with the OP.







Observation of PROFIBUS installation guidelines Detailed information on the installation guidelines for PROFIBUS and MPI subnetworks is available in the manual "SIMATIC S7-400 and M7-400 Programmable Controllers Hardware and Installation", Chapter 5 Networking in Entry ID: 1117849.   Observation of EMC guidelines Please strictly observe the EMC (electromagnetic compatibility) guidelines when installing.   Number of OP connections of the U Check the number of connection resources of your U. Refer here to the technical data of the U.   Defective OP interface In rare cases it might also happen that the interface on the OP is defective. In this event replace the OP.
