4.3.2. Hardware Configuration
The hardware setup used in this guide is illustrated below. It is composed of a Hot-Standby CPU, digital and analog I/Os modules, and 2 Ethernet TSX ETY 5103 communication modules for the management of the control and field networks. At least one Ethernet ETY module is needed to allow Hot-Standby capability.
4.3.3. CPU Configuration
In Unity Pro, concerning the CPU, from the Configuration tab, the address range used for the application is defined (State of global address fields).
4.3.4. Hot-Standby Configuration
Also from the CPU, in the Hot-Standby tab, we set the Hot-Standby runtime parameters.
Monitored ETY module
As seen in the Design Chapter, at least one monitored ETY module is required in a Hot-Standby system.
In the Topological address of the monitored Ethernet module, choose a ETY module that will be declared as Monitored.
Select Rack Slot 0.5
Logic Mismatch
This parameter defines the PAC mode if a program mismatch is detected between the Primary and the Standby.
Select Offline
Non-Transfer Area
The non-transfer area cannot be defined by the user on a Premium Hot-Standby system. An area of 101 word is set by default (%MW0-%MW100). The words located in this area are not transferred to the Standby PAC.
4.3.5. Ethernet Modules – TSX ETY 5103
This part describes the ETY modules configuration to set up the communication with the SCADA system and the Ethernet devices.
Controller Ethernet Network
Only the IP configuration needs to be configured in order to set up the communication between the SCADA system and the ETY module. No specific service is required.
IP Configuration
IP address: 172.20.101.57
Subnetwork mask: 255.255.0.0
The IP configuration is summarized on the screenshot on the next page.
Devices Ethernet Network
This module is dedicated to communicate with I/O Devices such as ATV71, TesysT, Advantys STB, Quantum, M340 and so on.
IO Scanning service is used to communicate between the controller and the devices.
The ETY module communicates with the I/O Devices via an Ethernet ring managed by MRP. The configuration of the ring is the same as the one described for the Control Network (see Chapter 4.2)
IP Configuration
IP address: 172.20.104.5
Subnetwork mask: 255.255.0.0
Module Utilities
The I/O Scanning service drives the communication between the module and the I/O devices.
From Module Utilities area, select Yes for IO Scanning.
IO Scanning
Set up of the I/O Scanning lines associated to I/O Devices:
- Switch SW10:
ATV71: 172.20.104.10
STB: 172.20.104.11
ETG100: 172.20.104.12
- Switch SW11:
ATV71: 172.20.104.20
STB: 172.20.104.21
- Switch SW12:
Quantum: 172.20.104.22
M340: 172.20.104.34
The I/O Scanning configuration is presented on the screenshot on the next page.
4.3.6. Redundant Digital I/O
Redundant digital I/Os implementation is performed, as described in the Design chapter, thanks to Telefast connection equipments (ABE7 ACC11 for inputs, ABE7 ACC10 for outputs).
Digital I/Os management does not require any specific configuration. Nevertheless, it is important to choose the proper output fallback mode according to the process.
For this STG, it has been decided to maintain the outputs state before the default.
4.3.7. Redundant Analog I/O
Redundant analog I/Os implementation is performed, as described in the Design chapter, thanks to JM Concept connection equipments
This paragraph describes the analog I/Os and JM Concept modules configuration in order to set up redundant analog inputs and outputs.
Analog Input
The measurement input is a voltage signal +/-10V. The original signal is duplicated and converted in 0-10V by a JMC module and these 2 signals are connected to both PACs (Primary and Standby) via TSXAEY414 modules.
TELIS 9000U2 (JMConcept) Configuration.
Set the configuration switches according to the input signal type: Voltage 0-10V.
INPUT SWITCH 1 2 3 4 5 6
On the module, from the menu, and using the user guide set the input signal type, then the output signal type.
ANALOG Input ANALOG Output
Mode : 1 channel Type : Voltage Scale : +/-10v
Decimal Point : « 00000 » Minimum scale : 0
Maximum scale : 10000 Resolution : 1 Pt
Scale : 0-10V Minimum Display : 0 Maximum Display : 10000
TSX AEY414 Configuration
In Unity Pro, from the TSXAEY414 module configuration tab, set a voltage input 0-10V.
select a 0..10V range on the channel 0
select a scale value of 0…10000
Analog Output
The output signal generated by the PAC via a TSXASY410 module is a 4..20mA current signal.
This type of signal is used because it is the only one accepted by the GK 3000 D1 communication interface for inputs. The signal is sent for outputs on the channel A or B according to the communication relays.
The set up of the commutation relays is detailed in the Implementation chapter.
TSX ASY410 Configuration
In Unity Pro, from the TSXASY410 module configuration tab, set an 4..20 mA output current.
Select a 4..20mA range on the channel 0
The signal has to be maintained on a default so, de-select Fallback
The scale value is locked to 0 -10000
GK 3000 D1 (JMConcept) Configuration.
On the module, from the menu, only the high and low limits of the input signal can be defined.
