Fixed as of: PLC Designer (version 3.28.0 and later)
Behavior in the new version:The error no longer occurs.
The AT project template has been modified, and the TaskHighPriority has been defined as a bus cycle task.
Description of the behavior:
A multitask project (e.g., Basic Application Template) is being used. In this project, a counter module is connected to an EPM-S131. An LM_FreeEncoder_ECAT has been attached to the counter module.
Upon startup, error message 20662 appears: "Initialization error on the encoder backplane bus."
Under what conditions does this behavior occur?
A multitask project (e.g., the L_FAST_Standard project template) is used, and, for example, an EPM-S131 with a counter module is connected. This results in the counter module being assigned the TaskFreewheeling task, which causes error message 20662.
Affected products:
PLC Designer version 3.24 or later
Application Template
Short-term measures:
In the controller, "TaskHighPriority" must be assigned to the bus cycle task in the PLC settings.
