Operating mode control
The operating modes are discussed in detail in Section 9.2, the control-/checkback
signals and handling information in Section 9.1.
The user must write the control signals to the user data block (AW-DB). The
POS_CTRL block transfers the control signals from user data block AW-DB to the
FM 353 and the checkback signals from the FM 353 to user data block AW-DB.
The FM must be initialized.
The Table below lists the control and checkback signals, with symbols in German
and English.
