Description of functions
When the _ET200S_FC_control function block is called, the cyclic data is written and updated
and jobs (such as reading/writing parameter) can be carried out.
The values in the input parameters periIn, setpoint, and ctrlDword are transmitted cyclically -
regardless of the busy, done, execute, and mode parameters - and the output parameters
periOut, actValue, and statusDword are updated cyclically.
Jobs are started with a rising edge on the input parameter execute. The type of data transfer
is selected in the input parameter mode.
You can choose from the following options in the input parameter mode:
● READ: Individual parameters are read from the ET 200S FC (factory setting).
● WRITE: Individual parameters are written to the ET 200S FC.
● DATA1: The drive parameter p0810 is set to 0.0 (command data set 1 of the drive active).
● DATA2: The drive parameter p0810 is set to 1.0 (command data set 2 of the drive active).
● RESET_ERR: Resetting of parameterization and drive errors.
A job is started with a rising edge on the input parameter execute and the output parameters
set to done = FALSE and busy = TRUE.
If mode = WRITE is selected, the parameters paraNumber, subIndex, and paraValueWr are
accepted with a rising edge on the input parameter execute. An active data transfer is indicated
by busy = TRUE. When a job is completed without errors, the following parameters are
displayed: busy = FALSE, done = TRUE, and error = FALSE. When a job is completed with
errors (parameterization errors), the following parameters are displayed: busy = FALSE,
done = FALSE, and error = TRUE. The error number of the parameterization error is displayed
in output parameter errorID. Parameterization errors are acknowledged with a rising edge on
the input parameter execute and mode = RESET_ERR selected. If acknowledgement is
