1.1
Interlocking functions
Bypassing signals
With this function, you can flag a block as bypassed. With a connection from the output
parameter
BypassAct
to an input parameter
BypLixx
of an interlock block, you can bypass
the corresponding input of the interlock block.
Additionally, you can define over the
Feature
bit Substitution value is active if the block is in
bypass (Page 57) if the block shall use the process value or a substitution value in case of an
active bypass.

With the parameter
BypLiOp
, you can decide whether the switching on/off will be done by the
input parameters which are connected in CFC or by the faceplate from an operator.
●
BypLiOp
= 0: In the "Parameter view", the operator can switch on/off the bypass function
over the parameter
BypPVOp
or
RstBypOp
. If
BypLock
= 1, you cannot make any change
to the parameters
BypPVOp
or
ResBypOp
. The button for switching the bypass functionality
on/off in the "Parameter view" is deactivated.
●
BypLiOp
= 1: With a connection of the parameter
BypPVLi
or
RstBypLi
, the bypass
function will be switched on/off.
If the bypass function is active, the output parameter
BypassAct
will be set from the block.

Settings for operator control and monitoring
1.2.1
Selecting a unit of measure
Coded unit of measure
The parameter
XXX_Unit
is used to specify the unit of measure for the corresponding input
parameter (XXX stands for a specific parameter, for example,
PV_Unit
). Entry is carried out
in the form of a code. Exactly one unit of measure is assigned to each code and is displayed on
the faceplate.
