Detailed Description
2.7 Program operation mode
2.7.6 Channel status
Interface representation
The current channel status is displayed in the interface. The PLC can then trigger certain
responses and interlocks configured by the manufacturer depending on the status at the
interface.
The channel status is displayed in all operating modes.
Channel statuses
The following channel statuses are available:
• Interface signal DB21, ... DBX35.7 ("Channel status reset")
• Interface signal DB21, ... DBX35.6 ("Channel status interrupted")
• Interface signal DB21, ... DBX35.5 ("Channel status active")
For a further explanation of the individual signals see Chapter 5.
The effect of commands/signals
The channel status can be modified through the activation of various commands or interface
signals. The following table shows the resulting channel status (assumption: status before
the signal -> channel status active).
"Channel status active" is achieved when a part program or
part program block is executed or when the axes are traversed in JOG mode.
