Functional Blocks

Utility Blocks

FLAG

FLAGARRAY

Description

Provides storage for a single two-state value which can be accessed as a simple Boolean (OFF or ON) value using the
PVFL parameter, or as one of two user-configured state values (for example, Running and Stopped) via the PV
parameter.

Function

•

Used to define two separate states (for example, Running/Stopped, Off/On) to indicate status of a particular input.

•

There are 2 user-configurable state descriptors, STATETEXT [0] and STATETEXT [1] that are used to describe
STATE0 and STATE1 respectively.

•

Current state of flag can be changed/read using PVFL (Boolean) or using PV (either STATETEXT [0] or STATETEXT
[1]).

•

Block also supports:

–

configurable access lock which determines who can write a value to the block (such as operator, engineer, or

other function block).

–

an Off-Normal Alarm whereby one of the flag’s states is configured as the normal state; whenever the flag

changes state, the Off-Normal Alarm is generated.

Inputs/Outputs

PVFL is the only exposed block connection, but you can expose other block parameters through the Configure Block
form in Control Builder.

STATE0

STATE1
STATETEXT [0..1]

Description

Provides storage for up to 1000 2-state values. The value can be accessed as a simple Boolean (Off or On) using the
PVFL [n] parameter. Where “n” is the number of the flag.

Function

•

Used to define two separate states (Off/On) to indicate status of a particular input.

•

Number of flag values (NFLAG) is user configurable.

•

Current state of flags can be changed/read using flag value (PVFL [n]) (Boolean).

Inputs/Outputs

Boolean output flags (PVFL [1..1000])

Parameters

ACCLOCK
NFLAG
