How To Simulate SICAM PAS IEC-104 Connectivity to Master SCADA using ASE2000

Overview

Regarding our customers now is using Master SCADA with IEC 870-5-101 and 104 protocol. All of RTU or SAS projects must provide this protocol and successfully pass the interoperability test. The new project of Substation Automation System has to be proof that the system is able to communicate to master SCADA via IEC 870-5-101 protocol.

During Commissioning or SAT, often the customer request to test the IEC-101 or 104 of our SAS using a standard protocol tester such us ASE2000. Even this is very simple test, sometimes if someone not familiar with this protocol tester, then it’s almost impossible to perform the test and the SAS project will be fail. This document provides the basic configuration of ASE2000 to perform connectivity test of IEC-104 protocol of SICAM PAS.

Basic Setup

1 How To Simulate IEC-60870-104 Protocol (Master SCADA) in Protocol Tester ASE2000

ASE 2000 communication test set is a protocol tester or simulator that able to simulate many kind of protocol. This tool is powerful, except the software GUI is not user friendly and minimal user guide available. This document will explain the detailed how to simulate IEC 60870-104 protocol of SICAM PAS using ASE 2000 as the Master SCADA simulator.

Before start the configuration of SICAM PAS and ASE2000. First of all, we need to connect an Ethernet cable of SICAM PAS PC and ASE2000 PC to an Ethernet switch such us Ruggedcom. Also, ensure that SICAM PAS has been installed IEC-101 and IEC-104 protocol license on it. Set the IP Address of SICAM PAS PC and ASE2000 PC with same class IP Address.

ASE2000 Basic Configuration

Please follow this step:

1. Click menu File and Select Protocol to IEC 870-5-104. To perform this, ASE2000 software must have IEC-104 protocol license installed on it.

clip_image007 clip_image009

2. From Properties/Protocol Specific/Host, enter the IP address of the SICAM PAS or any Controlled Station (such us RTU or IED device to be controlled). Basically, IEC-104 protocol only needs IP Address to make connection.

clip_image011

clip_image013

3. From Properties/Protocol Specific/IEC 870-5-104, review timers and message count parameter specific to IEC 60870-5-104 protocols. The defaults should be OK for most systems, but can be changed if necessary, depend on master SCADA configuration which will be simulated in this test.

clip_image015

4. From Properties/Protocol Specific/Exchange Defaults, enter the Common Address of ASDU in the Comm Addr field. This is valid only for Controlled Devices with a single common address. The procedure for devices with multiple addresses is described later

clip_image017

Exchange Configuration

Normal Communication

Normal communication to IEC 870-5-104 devices requires use of the Simulate Master function. Except for the TESTFR message, Send Once or Send Continuously will not work correctly.

For Simulate Master, all exchanges to be transmitted must be configured prior to starting the simulation session. In the simplest case, successful communication to a Controlled Station can be established by sending only STARTDT ACT. This message allows the Controlled Station to transmit point information according to logic configured in the device.

clip_image019

clip_image002Typically, the Interrogation exchange would also be enabled. This instructs the Controlled Station to send initial data for all points. Enabling both the STARTDT ACT and Interrogation exchanges to be sent once at startup obtains all initial data from the Controlled Device and enables it for transmission of point changes.

No other exchanges need to be enabled. The ASE2000 automatically transmits housekeeping messages required to keep the link open and active.

To configure the STARTDT ACT and Interrogation exchanges:

  • Double click the STARTDT ACT exchange to request the Edit Exchange Properties menu
  • Set the Frequency to 0 seconds
  • Check the Transmit exchange flag. Then Select OK

Repeat the above procedure for the Interrogation exchange

Other exchanges, such as command outputs, may be enabled to test other device features, but are not required. Other exchanges are enabled by following steps similar to those presented above. In addition:

The Frequency should probably be set to some value other than 0. A Frequency of 0 configures the ASE2000 to send the message once at startup. A non-zero Frequency causes the message to be sent periodically at the specified rate

Most other exchanges require additional configuration information such as an Information Object Address. Information specific to each exchange can be entered from the Edit Exchange Properties menu or from other menus accessible from there

clip_image002[6]

image After completing the above steps and steps described in the Basic Setup section, start communication by clicking the Simulate Master ICON clip_image007[5]or selecting File and Simulate Master.

If there’s any message response from SICAM PAS with “<--“ sign, it means that SICAM PAS is successfully connected to ASE2000 protocol tester.

SICAM PAS Configuration

The only requirement of connection between SICAM PAS to protocol tester or master SCADA is the IP Address of SICAM PAS PC shall be identical with protocol tester “Host Connection”.

clip_image002[8]

We can use the Default setting of SICAM PAS. There’s no any setting which necessary to change here.

clip_image004

The ASDU Address also not necessary to change, we can change the ASDU if the configuration of master SCADA request this setting. By default setting, for IEC-104, only IP Address of SICAM PAS PC is possible to make connection and perform the test.

clip_image006

Open SICAM PAS – Operation, update system if required then we’ll see that SICAM PAS already connected to ASE2000 protocol tester via IEC-104 protocol.

clip_image008

TESTFR

A sole exception to the requirement to send an initial STARTDT ACT message exists for the Data Link layer TESTFR ACT exchange.

The TESTFR ACT exchange can be configured for transmission by following the same procedures as for any other exchange. Additionally, TESTFR ACT may be sent with Send Once or Send Continuously. These functions cannot be effectively used with any other message.

Multiple Common Addresses

An IEC 870-5-104 device can contain data points in more than one common address. Additional setup steps are required for communication to a multiple common address device. Specifically, item 3 in the Basic Setup section configures the ASE2000 for operation to a single Common Address. If this setup step is followed, then messages received from a different Common Address will be unrecognized by the ASE2000 and will eventually result in a network disconnect.

For communication to a Controlled Device with multiple Common Addresses (multiple SAS, eg. FAT with many SAS project):

From Properties/Protocol Specific/Exchange Defaults, make sure that the Common Address of ASDU (Comm Addr field) is set to an *. This is the default setting and instructs the ASE2000 to recognize messages from any Common Address

Enable STARTDT ACT as explained in the Normal Communication section

There are two options for enabling an Interrogation. The first option is to send an Interrogation to the broadcast address, 65535. The second option is to send a set of Interrogation messages, one to each Common Address. In either case, do not use the default Interrogation exchange. Create one new Interrogation exchange for each request to be transmitted. Only one new exchange is required to send a request to the broadcast address. Multiple new exchanges are required to send separate requests to each Common Address

To create a new Interrogation request, either:

Highlight the default Interrogation exchange, select Edit/Copy and Edit/Paste, or Select Edit/Create Exchange Template and select Interrogation

For each new Interrogation exchange:

Double click the exchange to request the Edit Exchange Properties menu. Set the Frequency to 0 seconds. Check the Transmit exchange flag. Enter the Common Address, either 65535 for the broadcast address or a specific device Common Address. Select OK

To configure other exchanges, such as commands, for transmission:

Create a new exchange for each command to be transmitted by following steps as explained in step 4. Configure the message for transmission as explained in step 5.

Before start config SICAM PAS and ASE2000. First, connect RS232 of SICAM PAS PC to ASE2000 PC using a standard Null Modem cable, of course with cross serial TX-RX. Also, ensure that SICAM PAS has been installed IEC-101 and IEC-104 protocol license on it. If there’s RS416 due to redundant SICAM PAS server, in order to perform test we need to connect the RS232 cable to RS416 port which used as virtual COM Port.

Please follow this step:

1. Click properties - communication, in the channel tab make sure that you have right com port setting. In the Line tab chose constant as the carrier option, make sure the baud rate is same with SICAM PAS/RTU setting. This is COM Port of PC with ASE2000 installed on it.

clip_image002 clip_image004

2. Click Properties - Protocol Specific, In The Channel exchange defaults make sure that the DL address and Comm address' value is same with SICAM PAS setting. Check the Asynch and iec 870-5-101. Ensure that the values in that panel are same with SICAM PAS setting. Our customer recommended setting based on their master SCADA configuration: Data bits 8,1,Even and Length link is 2,2,3.

Apa itu Penyakit Chikungunya? Gejala, Pengobatan, dan Pencegahan

Apa itu penyakit Chikungunya? Sebenarnya saya masih awam dengan penyakit ini, namun beberapa hari ini di rumah dan hampir semua warga desa di kampung terkena demam tinggi disertai mual, muntah, bintik-bintik merah pada lengan dan nyeri-nyeri pada sendi sampai lemas dan kesulitan untuk bangun dari tempat tidur. Kebetulan adik dan ibu saya juga kena wabah penyakit ini, meski dikategorikan tidak sangat berbahaya namun sebisa mungkin harus dicegah dan menjaga lingkungan tempat tinggal bebas dari wabah nyamuk adalah sangat penting.

Semoga postingan kali ini dapat memberikan gambaran tentang Chikungunya dan bermanfaat. Sumber: http://www.medkes.com/2013/05/gejala-pengobatan-pencegahan-chikungunya.html

image Penyakit demam chikungunya merupakan penyakit yang berjangkit pada suatu kawasan atau populasi (endemik) yang disebabkan oleh virus keluarga Togaviridae (genus alphavirus) dan ditularkan oleh nyamuk Aedes aegypti. Nyamuk yang sama juga menularkan penyakit demam berdarah dengue. Meski masih "bersaudara" dengan demam berdarah, penyakit chikungunya tidak mematikan.
Virus chikungunya pertama kali diidentifikasi di Tanzania, Afrika Timur tahun 1952. Tidak heran bila namanya pun berasal dari bahasa Swahlii, artinya adalah "yang berubah bentuk atau bungkuk". Postur penderita chikungunya memang kebanyakan akan membungkuk akibat nyeri hebat pada persendian tangan dan kaki.

Gejala Chikungunya

Di lndonesia, demam chikungunya dilaporkan pertama kali di Samarinda tahun 1973. Kemudian berjangkit di Kuala Tungkal, Jambi, tahun 1980. Selanjutnya tahun 1983 merebak di Martapura, Ternate dan Yogyakarta. Setelah vakum hampir 20 tahun, awal tahun 2001 kejadian luar biasa (KLB) demam chikungunya terjadi di Muara Enim, Sumatera Selatan dan Aceh. Disusul Bogor bulan Oktober. Demam chikungunya kemudian berjangkit lagi di Bekasi (Jawa Barat), Purworejo dan Klaten (JawaTengah) pada tahun 2002.

Gejalanya adalah demam tinggi, sakit perut, mual, muntah, sakit kepala, nyeri sendi dan otot, serta bintik-bintik merah terutama di badan dan tangan, meski gejalanya mirip dengan demam berdarah dengue, pada chikungunya tidak terjadi perdarahan hebat, renjatan (shock) maupun kematian. Masa inkubasinya dua sampai empat hari, sementara manifestasinya tiga sampai sepuluh hari.

Pengobatan Chikungunya
Tak ada vaksin maupun obat khusus untuk chikungunya. Cukup mengonsumsi obat-obat simptomatik (pereda gejala) seperti obat penurun panas atau penghilang rasa sakit. Yang penting cukup istirahat, minum, dan makanan bergizi. Virus chikungunya ini termasuk self limiting disease alias akan hilang dengan sendirinya. Namun, rasa nyeri akan tetap ada dalam hitungan minggu.
Bagi penderita, sangat dianjurkan untuk makan makanan yang bergizi, cukup karbohidrat dan terutama protein serta minum sebanyak mungkin. Perbanyak mengkonsumsi buah-buahan segar. Sebaiknya minum jus buah segar. Setelah lewat lima hari, demam akan berangsur-angsur reda, rasa ngilu maupun nyeri pada persendian dan otot berkurang, dan penderitanya akan sembuh seperti semula. Vitamin peningkat daya tahan tubuh juga bermanfaat untuk menghadapi penyakit ini. Daya tahan tubuh yang bagus dan istirahat cukup bisa membuat rasa ngilu pada persendian cepat hilang. Minum banyak air putih juga disarankan untuk menghilangkan gejala demam.

Pencegahan Chikungunya
Satu-satunya cara menghindari penyakit ini adalah dengan menghindari/membasmi nyamuk pembawa virusnya. Nyamuk ini senang hidup dan berkembang biak di genangan air bersih seperti bak mandi, vas bunga, dan juga kaleng atau botol bekas yang menampung air bersih. Serangga yang bercorak hitam putih ini juga senang hidup di benda-benda yang menggantung seperti baju-baju yang ada di belakang pintu kamar. Selain itu, nyamuk ini juga menyenangi tempat yang gelap dan pengap.

Berdasarkan pengalaman selama ini, penyakit ini sulit menyerang penderita yang sama. Tubuh penderita akan membentuk antibodi yang akan membuat mereka kebal terhadap wabah penyakit ini di kemudian hari

Mengingat penyebar penyakit ini adalah nyamuk Aedes aegypti maka cara terbaik untuk memutus rantai penularan adalah dengan memberantas nyamuk tersebut, sebagaimana sering disarankan dalam pemberantasan penyakit demam berdarah dengue. lnsektisida yang digunakan untuk membasmi nyamuk ini adalah dari golongan malation, sedangkan themopos untuk mematikan jentik-jentiknya. Malation dipakai dengan cara pengasapan (fogging), bukan dengan menyemprotkan ke dinding. Hal ini karena Aedes aegypti tidak suka hinggap di dinding, melainkan pada benda-benda yang menggantung. Namun, pencegahan yang murah dan efektif untuk memberantas nyamuk ini adalah dengan cara menguras tempat penampungan air bersih, bak mandi, vas bunga dan sebagainya, paling tidak seminggu sekali, mengingat nyamuk tersebut berkembang biak dari telur sampai menjadi dewasa dalam kurun waktu 7-10 hari.
Penyakit chikungunya ini berkait dengan kesehatan lingkungan. Kesadaran menciptakan lingkungan yang bersih menjadi keharusan tiap orang. Halaman atau kebun di sekitar rumah harus bersih dari benda-benda yang memungkinkan menampung air bersih, terutama pada musim hujan seperti sekarang. Pintu dan jendela rumah sebaiknya dibuka setiap hari, mulai pagi hari sampai sore, agar udara segar dan sinar matahari dapat masuk, sehingga terjadi pertukaran udara dan pencahayaan yang sehat. Dengan demikian, tercipta lingkungan yang tidak ideal bagi nyamuk tersebut.
Berdasarkan pengalaman selama ini, penyakit chikungunya ini sulit menyerang penderita yang sama. Tubuh penderita akan membentuk antibodi yang akan membuat mereka kebal terhadap wabah penyakit ini di kemudian hari. Dengan demikian, kecil kemungkinan bagi mereka untuk kena lagi. (Village Voice)
