Functions (continued)
Reex functions editor
For applications requiring short response times (< 3 ms), the Modicon STB distributed
I/O solution allows you to create reex functions using the conguration and debugging
software. These reex functions act directly at the level of the island output modules
and therefore are not taken into account or processed by the island master. These
reex functions can be associated with “priority” I/O modules to ensure the reliability
of the response time.
A Modicon STB island can call up to 10 reex functions.
These functions are created from blocks whose inputs are activated by digital or
analog input channels and whose results activate a digital or analog output channel.
It is possible to nest two reex functions.
Reex types and function blocks
Various types of function block are available:
Boolean logic blocks: XOR block,
AND blocks with 3 inputs and 1 output
Timer/monostable blocks:
when working, when idle, upon activation
and upon deactivation
Up/down counter blocks: on a rising
or falling edge, from 0 to 65,535
Comparison blocks on signed integers
(- 3,768 to 32,767): i <, i >, < i >, i < and i >
Digital latch blocks: on state 0 or 1 or on
rising or falling edge, storing of state 0 or 1
Analog latch blocks: on state 0 or 1 or
on rising or falling edge, storing of signed
integer (0 to 65,535) or unsigned integer
(-32,768 to 32,767)
Documentation: A document entitled “Reex actions” is available on the CD-ROM
STBSUS8800 and on our website www.schneider-electric.com.
Advantys STB DTM
Advantys STB DTM software helps to congure STB islands. It is supplied as an
installation option with the software on the same CD(1)
It provides DTMs for STB Modbus TCP islands (STBNIP21) and STB Ethernet/IP
islands (STBNIC2212).
When used which Unity Pro v7.0, it provides the capabilities of:
 Creating and modifying STB island conguration via a vizualized conguration
interface within Unity Pro
 Conguration upload/download
 Monitoring
 Providing process channels for I/O mapping without the need of calculating
manually the mapping address and size
 Printing conguration
 Easy labelling without the need to export and import manually the user labels
 Process channels displaying with the representation of I/O data object structure
with either byte or bit level.
Advantys STB DTM is also functionnal with the following NOC master DTMs:
 Quantum 140NOC77101, 140NOC78000, 140NOC78100
 Premium ETC101
 M340 BMXNOC0401
