Operation Overview
The inputs and outputs are numerically represented as a Function Block ‘point’. The point is a function
block’s output value. Depending on the purpose of a function block the point may have a range of sub-
parameters available for defining the block’s function and the operational features & limitations of the
function.
The process of setting up function blocks and connecting function blocks to form an application uses
simple text lines therefore it is not necessary to learn a complex programming language. The settings
may be manually typed in to the device or, using the
FUNCPROG 141101
programming tool which
provides a visual representation of each block, an application text file may be created, saved and
downloaded to the device as a complete group of settings. Earlier versions of FuncProg may be used
but the latest feature settings will not be directly available in those earlier versions.
The ability to make single setting changes directly at the device makes for easy debugging and
commissioning.
The function blocks comprise:
Physical I/O for connection of input switches, sensors and output control devices
Network settings
In all cases points may be manually overridden for testing & commissioning purposes or for service
override.
Connection to the device for programming and service is via a terminal program such as HyperTerminal
(recommended). While on-line to the device it is possible to view point statuses and where applicable,
any dependent or influencing point’s connections. Statuses are updated live to the terminal screen
every 10 seconds or manually refreshed any time by pressing the enter key.
In additional to the predefined point displays a user-defined display is available for a customised point
summary related to an application. The user display may contain up to 32 lines of user text with or
without dynamic points included.
