Glossary

"Automatic mode" and "setup mode"
Program-controlled plants pose a significant safety risk for operators. EN 12417 "Machine
tools. Safety. Machining centers" and DIN EN 13128 " Safety of machine tools - Milling and
boring machines" define operating modes to ensure staff safety. A "setup mode" is required
for correct plant setup for "automatic mode". Plant functions in this mode are limited
compared to automatic mode. Devices have to be moved with the handwheel or in jog mode.
"Offline" operating mode
In this operating mode, the HMI device and the PLC do not communicate over the
connections configured in the project. You can operate the current project on the HMI
device. However, project data are not transferred.
"Online" operating mode
In this mode, the HMI device and PLC communicate. You can operate the plant with the HMI
device in accordance with the configuration.
"Transfer" mode
In this mode, you can transfer a project from the configuration PC to the HMI device or
backup and restore HMI device data, for example.
Acknowledge
Acknowledgment of an alarm confirms that it has been noted.
Automation system
An automation system is a controller of the SIMATIC S7 series, such as a SIMATIC S7-300.
Backtransfer
Backtransfer is the backup of a project from the HMI device to a configuration PC.
Bootloader
The bootloader is used to start the operating system and is started automatically after HMI
device power on. The Start Center opens after the operating system has loaded.
