Automatic operation check
BAYCON has an amount of information that concerns the permission for
automatic operation. This information is made available at the
AU_OP_Vx outputs. Other elements can combine this information to a
signal to an automatic function indicating permission for operation.
Parameters
T_CAN_RE
Timeout when the reset of the reservation acknowledgement is not done
by the requesting bays, for example, because of communication error.
3.2.2 COMCON
COMCON acts as an interface between the possible operator places and
the bay and the apparatus-control program. The validity of operator places
is indicated on the REMOTE, STATION and LOCAL inputs. See the
configuration example in “Operator place selection” on page 34. Only the
signals from the operator place(s) that are valid are executed. When a
change occurs, COMCON checks validity and forwards the commands to
the outputs, if they are correct.
From station level, COMCON supports two ways of command execu-
tions:
1. From station MMI.
2. From remote gateway.
In the first way, that is normally used as standard from the station MMI
(see item 1 in Fig. 8), only one selection input is activated, S_SEL_O or
S_SEL_C. COMCON sets the RQ_SEL and the concerning direction out-
put, OPEN or CLOSE. After the SELECT input is set by BAYCON, it
allows the execute command S_OPEN and S_CLOSE to pass through.
These execution inputs can be set at the same time or before SELECT is
activated. Then the EXECUTE output is also activated. The “Reservation
function” on page 26 describes the reservation method.
