About us
Overview
The TSX ASY 800 is a module with 8 analog outputs not isolated from each other. This module offers the following ranges for each output, according to the selection made during configuration  :
Summary
The TSX ASY 800 output module performs the following functions :
Description
Details of the functions are the following :
Address
Component
Function
1
Connection to Process
  • hardware connection to the process through a 25-pin Sub-D connector,
  • Protecting the module against voltage spikes.
2
Adaptation to Various Actuators
  • The adaptation is performed on voltage or current.
3
Converting Digital Data to Analog Signals
  • For voltage, conversion is performed on 13 bits + polarity sign (-8192 to +8191),
  • For current, conversion is performed on 13 bits (0 to +8191),
4
Transforming application data into data directly usable by the discrete/analog converter
-
5
Interfacing and Communications with Application
  • managing exchanges with CPU,
  • geographic addressing,
  • receiving, from the application, configuration parameters for the module and channels, as well as numeric setpoints from the channels,
  • sending module status back to application.
6
Module Power Supply
-
7
Module monitoring and sending error warnings back to application
  • converter test,
  • testing for range overflow on channels,
  • verifying that terminal block is present,
  • watchdog test.
8
External 24V Power Supply to Outputs
-
Output refresh time
The maximum delay between transmission of the output value on the PLC bus and its effective positioning on the terminal block is 5 ms.
Behavior in case of fault in External Power Supply to Outputs
Should there be a fault in the external power supply to the outputs, all outputs for module TSX ASY 800 switch to 0 (zero).
NOTE: Should there be a fault in the external power supply at the same time as a fault in the wiring terminal, only the power supply failure is reported.
Writing to Outputs
The application must provide the outputs with values in the standardized format:
These values must be written in the words %QWr.m.c.0 to 7 for channels 0 to 7 of module.
