Task integration (call)
The _ET200S_FC_control FB is designed to be called in a cyclic task and must be called in
this task during each task cycle. The execution of a job can take several cycles. The user
decides which cyclical task the _ET200S_FC_control FB is called in. There are no restrictions
with respect to this in the _ET200S_FC_control FB. The call can be performed in all cyclic
tasks. A fixed time frame (e.g. IPOSynchronousTask) is not required for processing.
A separate instance of the _ET200S_FC_control function block must be created for the control
and communication tasks of each frequency converter used.
Error messages
The drive errors of the ET 200S FC are output at the output parameters driveError and
driveErrorId of the _ET200S_FC_control FB. The output parameter driveErrorId displays the
associated error number (from r0947). For a description of the error numbers, see the
SIMATIC ET 200S FC Frequency Converter Parameter Manual (03/2005 Edition).
Rectify the cause of the drive error. Drive errors are acknowledged with a rising edge on the
input parameter execute and mode = RESET_ERR selected.
Parameterization errors are signaled at the output parameters error and errorID , and reset
with a rising edge on input parameter execute and mode = RESET_ERR selected.
