TWIDO ZELIOS & TESYS LU9GC3

Description: How to connect Twido with tesys and zelios using TESYS LU9GC3 under Modbus RS485

In 1st picture there is the connection of a Twido modbus (any Twido model)
1 : Modbus RS485 Communication module LULC031
2 : Connection cable VW3A8308R with RJ45 connector on each end. Used to connect TESYS and distribution unit
3 : Modbus distribution unit LU9GC3. Used to connect the Twido and multi TESYS starter controllers via RJ45 connectors

 The 2nd picture is showing the internal wiring of the modbus distribution unit

The 3rd picture is showing how to connect  a Twido Master cpu with 2 or more (up to 29slaves) slave Zelios (internal wiring) using the modbus spliter box Tesys LU9GC3. The polarization resistor must be manage by the master.

Note . Resistors of 4,7KΩ are implanted inside Twido CPU .

At the 4th picture is showing the above implementation on how to connect them in reality. The modules that are neccessary to implement this connection are :

1 : One Twido master Cpu (any model)

2 : Two (or more) Zelios with their modbus extension module SR3MBU01BD

3 : One Tesys LU9GC3 modbus RS485 distibution unit

4 : Two cables VW3A8306R03

5 : A connector unit VW3A8306TF03

6 : Two termination resistors VW3A8306RC

The implementation of the program will be added soon or in a next post 

Programming/animating Twido via existing RS485 bus.

Description:
- This document describes the possibility to connect Twidosoft to Twido on existing RS485 bus for programming or monitoring purposes using Modbus communication protocol. Primary (built-in) or additional RS485 communication adapter may be used.

Hardware
One or more Twido controllers (optionally with additional RS485 communication adapter installed.)
TSXPCX1031 serial programming cable Or TSXPCX3030 USB programming cable
mini-DIN female connector
Software
MS Windows XP SP1 / SP2
Twidosoft v3.2
Twido fw. 3.20

1. Tested configuration

You will need an adapter (mini-DIN to free wires) in order to connect TSXPCX 1031/3030 programming cable to screw terminal block.
Adapter wiring:

Create an adapter using spare mini DIN female connector.

Use pins 1, 2, 7 (data+, data-, GND). It’s necessary to connect external 5V DC power supply to pins 8 (5V) & 7 (GND) to supply the RS232<->RS485 converter inside the cable. It’s possible to use 5V from PS/2, USB or Twido’s mini DIN connector

Notes: -When connecting to Port 1, pins 5 (DPT) and 7 (0V - GND) must be interconnected, otherwise Twido sets the port for communication with Twidosoft (Address 1, 19200kb/s, no Parity) and ignores the user setting.

-Other modbus devices than Twido may also be present on the network.

2. Setting up connection in Twidosoft

You will need to modify the connection preferences: File – Preferences – Connections Management

Connection type: Serial for TSXPCX1031 serial programming cable
USB for TSXPCX3030 USB programming cable

IP / Phone: Corresponding COM or USB port
P-Unit / Address: @ - This setting lets you choose the address before every connection.
Baud rate, Parity, Stop Bits....: Use the exact setting of the network you wish to connect to.
Confirm the changes, select your connection from the drop-down menu and confirm again.

3. Connection

Set the rotary switch on programming cable into position 1 – OTHER MULTI.
Click on the connect button.
Select the address of PLC you want to connect to.
Confirm.

Note: The line must be silent while connected with Twidosoft. If there is any other communication, the connection will fail.
This connection is not suitable for firmware update (possible only through Port 1 with default comm. setting). Communication failure would result in a permanent damage to the controller

MONITOR PRO TAG COUNT CLARIFICATION

Hardware Standard PC
Software MS Windows XP SP2
Monitor Pro 7.2
Monitor Pro 7.6

MONITOR PRO 7.6

The total tag count can be found by right-clicking on the application in
Config Explorer, slide down to "View" and then open "Application Size".
This returns the total number of tags the app is configured for and the total
number of user defined tags.
The total tag count restriction on a Monitor Pro Server is based on the
user-defined tags. Schneider Electric defined global tags such as
SECTIME are not considered user defined tags are excluded from the total
user defined tag count limit.
e.g. If a customer has a 1024 total tag count license then he can have 1024
user defined tags.
I/O tags are defined by the number of tags entered in a device driver,
Ioxlator, or ECI table. It is not based on the number of registers addressed
in the PLC. For example, if you wants to read HREG 40001 into MyTag1
and into MyTag2, that counts as 2 I/O tags even though you are reading
from the same register in the PLC. In other words if the user defined 5 read
tables with 10 tags each in his netdtl driver table, then he has configured
50 I/O tags.

Unfortunately no tool exists to display the I/O tag count. The user has to
manually count his I/O entries.
