Manual for Configuration, Installation and Maintenance

Glossary

Function Block

Function blocks define the capabilities of the high level

 

 

measurement and control available in the device.

 

 

There are many possible function block capabilities

 

 

contained in a device such as analog input, discrete

 

 

input, discrete output, signal characterizer, arithmetic,

 

 

integrator, PD or PID control, input selector or analog

 

 

output.

 

 

 

 

Analog Input (AI)

Scanned by the Linking Device.

 

Function Block

 

 

 

 

 

Multiple Analog

Provides up to 8 variables in one function block,

 

Input (MAI)

reducing scan times.

 

Function Block

 

 

 

 

 

Mode

Target - The mode requested by the operator

 

 

Actual - The current mode of the block which may

 

 

differ from the target based on the current operating

 

 

conditions. The actual mode is calculated during block

 

 

execution.

 

 

Permitted - The modes allowed by target during

 

 

operation

 

 

Normal - The desired operating mode of the block.

 

 

 

 

Mode: Out of

In this mode the algorithm of the block is no longer

 

Service

being executed and any outstanding alarms will be

 

 

cleared. This is the highest priority mode.

 

 

 

 

Mode: Auto

In this mode the block algorithm is being executed with

 

 

new value and status as well as mode being computed

 

 

each Macrocycle or execution of the block

 

 

 

 

Mode: Manual

In this mode the block output is not being calculated

 

 

although it may be limited. It is set directly by the

 

 

operator through an interface device.

 

 

 

 

Macrocycle

The period of execution in which the function block

 

 

schedule is defined.

 

 

 

 

Schedule

The rate and relative time which function blocks

 

 

process their inputs and generate their outputs. The

 

 

schedule defines when a function block is triggered to

 

 

start execution

 

 

 

 

Link Master

A link master device is a device that is capable of

 

 

becoming the LAS. There is a bid procedure that is

 

 

followed that selects the link master device with the

 

 

lowest node address.

 

 

 

 

Link Active

The LAS performs five functions:

 

Schedule Device

Maintains the schedule to send compel data (CD)

 

 

messages (DLPDU's) to devices on the network. This

 

 

is the highest priority function.
