Schneider Electric 140DAO84010 Overview

Modicon 140DAO84010

The Modicon 140DAO84010 is a 16- output module manufactured by Schneider Electric for use on the Modicon Quantum I/O station.  The 140DAO84010 is a part of the EcoStruxure line of control modules.  These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry I/O Modules from other manufacturers such as Modicon and ABB.

Flat Addressing for the 140DAO84010

Flat addressing is used when memory overlapping control is needed. 

How are the numbering channels arranged on a discrete I/O bit? The Schneider Electric 140DAO84010 discrete I/O uses the same strategy as the other Quantum I/O modules as it begins numbering with one and counts forward to the maximum number that is supported by the module. The 140DAO84010 is a 16-output module which numbers starting at one and counting forward to sixteen. For the software channels, however, the number begins at 0, which stands for the least significant bit in a word (LSB). The Schnieder Electric Quantum I/O includes their lowest channel mapped to the most significant bit (MSB). 

The Schneider Electric Modicon Quantum 140DAO84010 output module can be configured as either 16 contiguous discrete % M output references, or as one %MW output word.  

Word Addressing as opposed to Bit Addressing concerning the 140DAO84010

The Quantum mainly discrete I/O modules can be configured to deliver their I/O data in two different formats. The two formats included with the mainly discrete I/O modules are word format and bit format. The Modicon I/O module format is able to be chosen at the time of configuration. The selection is done by selecting either %IW (%MW) or %I (%M). How do you access a single bit form an I/O module using an I/O word? If you need to access a single bit from an I/O module configured to use an I/O word, you can use the syntax %word.bit. 

Topological Addressing—800 Series I/O Modules with Control Expert Accessing I/O Data Values Use topological addressing to access I/O data items. You can find the topological location for the 800 series module with Control Expert using: %[\b.e\]r.m.c[.rank].

IODDT Addressing for the 800 series

What is the benefit of using IODDT addressing? IODDT Addressing allows all info, both bits and registers, related to a channel. The information is then handled through a user-defined variable. The chosen user-defined variable is defined in the Control Expert data editor. This is done by selecting the appropriate IODDT for the module as a data type. You must specify the topological address of the module using the following syntax: %CH[\b.e\]r.m.c.

The Modicon Control Expert allows for a couple of IODDTs. These IODDTs are either generic and can be used for several I/O modules or belong to one specific module.
