• Enabling the opening command: the function is used to block the operation of
the opening command. This block signal also affects the OPEN input of
immediate command.
• Enabling the closing command: the function is used to block the operation of
the closing command. This block signal also affects the CLOSE input of
immediate command.
The ITL_BYPASS input is used if the interlocking functionality needs to be
bypassed. When INT_BYPASS is TRUE, the apparatus control is made possible
by discarding the ENA_OPEN and ENA_CLOSE input states. However, the
BLK_OPEN and BLK_CLOSE input signals are not bypassed with the interlocking
bypass functionality since they always have the higher priority.

Opening and closing operations
The corresponding opening and closing operations are available via
communication, binary inputs or LHMI commands. As a prerequisite for control
commands, there are enabling and blocking functionalities for both opening and
closing commands. If the control command is executed against the blocking or if
the enabling of the corresponding command is not valid, CBXCBR, DCXSWI and
ESXSWI generate an error message.
Opening and closing pulse widths
The pulse width type can be defined with the Adaptive pulse setting. The function
provides two modes to characterize the opening and closing pulse widths. When
the Adaptive pulse is set to "TRUE", it causes a variable pulse width, which means
that the output pulse is deactivated when the object state shows that the apparatus
has entered the correct state. If apparatus fails to enter the correct state, the output
pulse is deactivated after the set Operation timeout setting, and an error message is
displayed. When the Adaptive pulse is set to "FALSE", the functions always use
the maximum pulse width, defined by the user-configurable Pulse length setting.
The Pulse length setting is the same for both the opening and closing commands.
