1. OVERVIEW

Please read this information before working with Twido 
products.
For general features, please refer to the online help delivered
on the TwidoSoft CD and installed with the control software.

===============================================================

2. RECOMMENDED SYSTEM REQUIREMENTS

A] Software
- PC-compatible computer with a 300 MHz Pentium processor,

- Modem: It's possible to use a modem connected to the 
  PC-compatible computer. You must install the modem under the
  Windows operating system, and then select the modem by
  the sequence: 
  "File" menu, and then "preferences" of Twidosoft.

4. LATE NOTICES

DOCUMENTATION
The documentation files are available in the "DOC" directory
at the root of the Twidosoft CD.
Software reference guide    : TwdoSOFT.pdf, TwdoSW.pdf
Hardware reference guide    : TwdoHW.pdf
Assistant executive loader  : Twel.pdf

RUNNING MULTIPLE INSTANCES OF TWIDOSOFT ON THE SAME PC
TwidoSoft is not designed to run multiple instances of the
software on a single PC.

ON LINE HELP INDEX PREPARATION
When you use the on line help index, if a message appears to 
indicate the index creation each time, and your PC-compatible
computer operation system is Windows XP, then check the 
directory ..\Twidosoft\bin, in order to verify if you have 
writing rights in this directory.

LADDER EDITOR
If you use the function keys (F2 to F12, or icon selection) to
select the object you want to insert in a rung, this key will
be active for only one insertion. To make multiple insertions, 
use the association with the Ctrl key, then the effect of the
function key (or icon selection) will be kept.

CHANGE BASE CONTROLLER TYPE FIRST
Validation and analysis are made with respect to the controller
type. It is recommended that you start your application
development by selecting the target Controller type first. In
this way, your system configuration will only consider the
appropriate functions and maximum limitations.

MODEM MANAGEMENT BY THE CONTROLLER
When a modem is configured on a communication port inside the
application, the Twido controller sends an initialization 
string (HAYES protocol) to the modem at power up.


AS-INTERFACE MODULE MANAGEMENT (TWD NOI 10M3)
Twidosoft offers two screens for the AS-Interface master 
module management. A configuration screen and a debug screen.
The debug screen shows in connected mode, at the bottom, red
information to indicate a non active state, but not an error,
as defined in the IEC standard IEC 62026-2 (2000-07).

AS-Interface SAFETY PRODUCTS IMPLEMENTATION:
- The A2SI integrated circuit version of the AS-Interface 
  safety slaves must be higher or equal to V3-7 (Rev C) . 
  All the Schneider AS-Interface safety slaves ASISSLxx 
  implement the V3-7 (Rv C) version since week 22 of 
  year 2003.
- For the ASISSLC1/ASISSLC2 products, the cable length 
  connected to the M12 has to be stricly less than 3meters 
  (ex: 2m).
- Take into account the Schneider EMC manual recommendations, 
  especially:
   . the AS-Interface cable and inout/output cables must be 
     far enough from the power cables.
   . connect the earth to the Gnd AS-Interface power supply 
     plug ( connector called Gnd or Shd near the ASI+/ASI-), 
     connect the AS-Interface master Gnd and the AS-Interface 
     safety monitor PE.

CLEARING CONTROLLER MEMORY
There may come a time when you want to initialize the 
controller memory to the original factory settings. This can be
accomplished in one of two ways. 
First, you can use TwidoSoft and select "Erase" from the 
"Controller" main menu. From the Erase dialog, select "Erase 
all". 
The second method is to use the operator display (TWD XCP ODC 
or ODM). Simply depress and hold any of the keys and power
cycle the unit. When power is restored release the key and you
will note that the controller is in NCF (non-configured mode). 

REAL TIME CLOCK UPDATE
The RTC update using the system bits and words must be done
using the following sequence:
	- Set to 1 the %S50 (disables the date and time
          update by the operating system),
	- Update system words %WS50 to %SW53 (year, month,
          day, hour, ...),
	- Update the system word %SW60 with the correction
          factor written on the RTC accessory (TWD XCP RTC),
	- Set to 0 the %S50.

PROGRAM ANALYSIS  
Missing point from Program analysis:
-  Do not leave empty lines between a subroutine (%SR1:), 
   label (%L1:), or grafcet definition (=*= 1) and the initial
   instruction of that section.

PID Autotuning Feature: 
Diagnosis of error "Error calculating Kp" : 
The possible causes are : 
- The process was perturbed when autotuning and the process static gain evaluation was distorted.
- The process variable transient response is not big enough for the autotuning to determine the static gain.
  In that case, the output setpoint, if possible, can be increased.
- The sampling period may be too small regarding the process dynamics,hence it may be increased. 
- Eventually, several of the above factors can be mixed together. It is necessary then to modify
  the output setpoint, the sampling period and to make sure no perturbation disturbs the process while autotuning.

5. TWIDO CONTROLLERS OPERATING SYSTEM INFORMATION

This CD contains the files of TWIDO controllers operating 
systems for version v1.12 to v2.1
These operating systems can be transferred by means of the OS 
loader, available via the "Tools" menu of TWIDOSOFT.
In order to obtain the latest product functions it is 
recommended to transfer the most recent compatible version 
(latest software version = SV).

The compatibility table below shows the different OS software
versions associated with the technology bases of controllers:

TABLE:

Technology Base			  	Software Versions

Compact:
TWDLCAA10DRF				SV1.12, SV2.0, SV2.01
TWDLCAA16DRF 				SV1.12, SV2.0, SV2.01
TWDLCAA24DRF 				SV1.12, SV2.0, SV2.01
Modular:
TWDLMDA20DUK 				SV1.12, SV2.0, SV2.01
TWDLMDA2DTK 				SV1.12, SV2.0, SV2.01
TWDLMDA20DRT 				SV1.12, SV2.0, SV2.01
TWDLMDA40DUK 				SV1.12, SV2.0, SV2.01
TWDLMDA40DTK 				SV1.12, SV2.0, SV2.01

OS file example:

 The binary file name of the TWDLCAA16DRF SV1.12 controller 
 will be: TWIDO16_V0112.TFW;
 The binary file name of the TWDLMDA40DUK (or TK) SV1.12 
 controller will be: TWIDO40_V0112.TFW.

The OS loader allows to choose the (TWIDO) target controller
binary file as well as the requested software version.

Compatibility is always given in incremental order of the OS
index.

Previous existing versions:
V1.0, V1.10, V1.11, V1.12, V1.00 P2, V2.01 P2, for this functional level, 
please use the V1.50 P2 version, available on this CD.

Reminder:

Warm restart
From V1.11 version, the compact controllers performs exactly
the same restart than the modulars. See documentation section 
"Dealing with Warm Restart" and don't take into account the note
concerning the compact controllers forever.

Compatibility information: 
Hardware: All hardware have similar behavior
Version: full compatibility from SV1.00 to SV2.5
