Figure 305: Enabling and blocking logic for CLOSE_ENAD and OPEN_ENAD signals
Opening and closing operations
The 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 (CLOSE_ENAD and
OPEN_ENAD signals). If the control command is executed against the blocking or
if the enabling of the corresponding command is not valid, CBXCBR and DCXSWI
generate an error message.
When close command is given from communication, via LHMI or activating the
AU_CLOSE input, it is carried out (the EXE_CL output) only if CLOSE_ENAD is TRUE.
If the SECRSYN function is used in “Command” mode, the CL_REQ output can be
used in CBXCBR. Initially, the SYNC_OK input is FALSE. When the close command
given, it activates the CL_REQ output, which should be routed to SECRSYN. The
close command is then processed only after SYNC_OK is received from SECRSYN.
When using SECRSYN in the “Command” mode, the CBXCBR setting
