5 Fw Concepts & Tools Trending Tool Exception Handling FSM Miscelaneous 5

6 WinCC-OA Trending - I WinCC-OA provides trending capabilities: Plots values from the Value Archive or Oracle RDB Archive. WinCC-OA is a SCADA tool, not an analysis package. A WinCC-OA connection to ROOT developed by Atlas. Since (PVSS) Version 3.6, WinCC-OA has been using the Qt graphics package Plugins EWO allow to implement new widgets Fw3DViewer FwWebViewPlus In the meantime: 6

7 WinCC-OA Trending - II 7

8 WinCC-OA Trending - III Providing line and bar trend Value over time widget Value over value (XY-plot) Any number of pens (curves) Scales can be set individually to visible/hidden Flooding of curves Color, line width, style individually selectable Ruler and legend, zooming, panning Ready-to-use trend application ( VarTrend ) Up to 6 pens (curves) in one display Mixing of compressed (averaged) and original data 8

9 WinCC-OA Trending - IV Sysmgm> Reports> Variable Trend there is a wizard to define a trend and view it in its own window, but 9

10 Fw Trending Framework provides commonly requested functionality. You can group your trend definitions into a tree structure Notation Pages Plots Curves... functionality and look&feel will be modernised soon using latest features of WinCC OA 3.15 trending widget 10

11 Trending Exercise (together) Do this together 11

12 Open Trend Editor-Navigator (T.E.N.) Open Trend Editor/Navigator -p fwtrending/fwtrendingmain.pnl menubar -iconbar 12

13 Define a Trending Plot Press Manage Plots/Pages button. Select Trending Plot (Value over time); Create. Plot configuration window opens PlotName=CAENCrateFanSpeed (Name = DPE = no spaces!) PlotTitle=CAEN Crate Fan Speed (Title. Spaces allowed.) 13

14 Defining a Plot (cont.) Select the DP Element (DPE) to plot: Under DPT = FwCaenCrateSY1527, Select DPE = dist_nn:caen/caencoursecrate.fanstatus.speedfan1 Set Legend Text = SpeedFan1 Make Y axis visible You now create entries for 2 more fan speeds Apply! Save As Saves a new plot definition with a different Name. Don t forget to give the new plot a different title first! Linear Steps 14

15 Result: Right click it to open the Fw Trend viewer 15

16 The Fw Trend Viewer Scroll on an axis to zoom it Drag a region to zoom in on it Middle mouse press shows values Click in area: fixed ruler CTRL+Middle mouse or SHIFT-Arrows: move the ruler Middle mouse/shift+drag: Diff ruler Hide/View the axes Link/Unlink the axes (in config panel) Logarithmic Axis (NB: Be well zoomed out!) Right-click: shows a menu... and more. See the help! 16

17 Organising plots in a tree (Why?) Exercise!! (Together.) Place your CAENCrateFanSpeed plot in the tree of plots under HVPlots. First, add an HVPlots node into the tree: Edit Mode> Right click > Add > Add Node 17

18 Organising plots - II Next, Right click on HVPlots >Add > Add Existing Plot/Page Navigator mode; Right click > View 18

19 Putting a plot in a panel How can I put a Fw Plot into my own panel? Gedi > View > Catalogs > fwcomponents > fwtrending (You may need to Right-click > List View mode) fwtrendingplotopenbutton puts a button on your canvas. Drag & drop this catalog item. Specify which plot the button should open: Righ-click: List-View mode Save and run as myplotbuttondemoparent.pnl 19

20 Putting a plot in a panel directly From the fwtrending catalog, drag and drop the fwtrendingfaceplate 20

21 Putting many Plots in a panel (Page) Back in T.E.N. > Manage Plots/Pages, this time create a Trending Page. Name= VertexHVPage Title= Vertex HV Page of Plots. Select for 2 x 3 plots on the page Insert your 2 plots 21

22 A Page of many Plots - II Right click 22

23 Add your Page into the TEN tree TEN > Editor mode > Right click on HVPlots > Add > Add existing Plot/Page 23

24 Viewing plots - II How else can I put Fw Plots into my own panel? From a script (of course!) Use fwtrending_addfaceplate() which calls addsymbol() for you AddSymbol is demonstrated in the optional exercise: \CourseMaterialsForStudents\Exercises\Exercise AddingPanelsIntoPanels\addingPanelsIntoPanelsAtRunTim e.pdf 24

25 Framework Online Help I just suggested you call fwtrending_addfaceplate() but where is that documented? In the Framework Help(!) which covers Framework libraries Framework panels 25

26 Fw Panel Help Pressing the help icon on any Fw panel takes you to that panel s help page. So, for example, pressing the Help icon on the DEN page will take you to <yourfwinstallation> s DEN Help html page: /opt/scada/pvss_projects/fwcomponents_ / help/en_us.iso88591/ fwdeviceeditornavigator/panels/ fwdeviceeditornavigator/fwdeviceeditornavigator.htm 26

27 Fw Library Help Any other entries in the Fw Help (both panels and libraries) can be accessed by clicking up and down a few levels. Go up to /opt/scada/pvss_projects/fwcomponents_ /help/en_us.iso88591 Then click down into the fwtrending help: fwtrending > fwtrending.htm Scroll down. Under Libraries, click All Functions Under - a - locate fwtrending_addfaceplate() in fwtrending.ctl We have prototype of integration Fw Library Help into the WinCC OA help system (e.g. right-click on function in GEDI) Available for CtrlRDBAccess extension. 27

28 fwtrending_addfaceplate() Note the Fw Exception Handling 28

29 Fw Concepts & Tools Trending Tool Exception Handling FSM 29

30 Fw Exceptions Exception handling as a language construct in CTRL is relatively recent, more recent than most of the Fw code. If you call Fw routines, you need to know how they pass exceptions back to you. Exceptions are implemented in the FwCore component, fwgeneral section 30

31 How Fw raises an exception A called function that wishes to raise an exception will: call fwexception_raise(); return; NB: Unfortunately, the return is not automatic as part of fwexception_raise() Some of function return a result code in addition: 0: OK -1 (or any other value): PROBLEM -> check exceptioninfo 31

32 Raising an exception (details) fwexception_raise (dyn_string &dsexceptioninfo, string exceptiontype, string exceptiontext, string exceptioncode) This routine takes 4 arguments. The free text arguments 2,3 and 4 describe the problem. The routine concatenates these 3 strings into one and appends them as a single new entry onto any existing dsexceptioninfo in the dynamic array. The code will then return (i.e. abort here),eg: { } fwexception_raise(dsexceptioninfo, "ERROR", "The data point name is not valid. "+ "Valid characters are A..Z, a..z, 0..9 and _", ""); return; 32

33 Handling an exception After calling a Fw routine, you should test if any exceptions were raised within it: 33

34 Handling an exception from within a UI panel // Example of exception-handling in a panel: main() { dyn_string dsexceptioninfo; fwsomecomponent_somefunction(param, dsexceptioninfo); if (dynlen(dsexceptioninfo) > 0) { fwexceptionhandling_display(dsexceptioninfo); return; } // More code... } // END main 34

35 Handling an exception from within a CTRL manager // Example of exception handling in a control script: bool myfunction() { dyn_string dsexceptioninfo; fwsomecomponent_somefunction(param, dsexceptioninfo); if (dynlen(dsexceptioninfo) > 0) { DebugTN(dsExceptionInfo); return FALSE; } // ENDIF // More code... } // END myfunction 35

36 Handling an exception from within a CTRL manager // Example of exception handling in a control script, with result code bool myfunction() { dyn_string dsexceptioninfo; int rc = fwsomecomponent_somefunction(param, dsexceptioninfo); if (rc) { // compact notation for rc!=0 DebugTN(dsExceptionInfo); return FALSE; } // ENDIF // More code... } // END myfunction 36

37 Exceptions in new code No code patterns for the new exceptions have been agreed by the JCOP Fw Working group yet. Some unapproved (yet) suggestions exist Proposed solution is already available in the fwgeneral subcomponent of the FwCore, yet not used at the moment. Because they re unapproved / under-development / subject-to-change, they re unreleased (in other words, not world-readable.) For the moment: follow the existing Fw Exception conventions. 37

38 Achtung! Attention! There exists another error-reporting channel in WinCC OA: last error Checking the error: dyn_errclass err=getlasterror(); if (dynlen(err)) {...} Still used (instead of exceptions) by certain builtin function, notably dpget() / dpset() Not to be confused with the new throw() / try{} / catch{} / finally{} / getlastexception() 38

39 Working with Fw Libraries If you don t understand the help ;-) you can always look at the source code Remember, the source code of the Fw CTRL libraries (.ctl files) is all in your Fw path: <fwcomponents_yyyymmdd>/scripts/libs/ 39

40 Another example The fwdevice_copy() routine is in the fwdevice component in the fwdevice.ctl library source file. You can view (but please don t edit!) the library source file with GEDI > Edit > Edit CTRL Lib Choose <fwcomponents_yyyymmdd>/scripts/libs/fwdevice/fwd evice.ctl The editor opens. Navigate to the routine of interest (see the selection list on the left) 40

41 Fw Source Code 41

43 Fw Concepts & Tools Trending Tool Exception Handling FSM 43

44 Fw & Finite State Machines You might have already heard of it... In the Control Room, the operators will control your hardware from within an FSM. (They will not run your panels directly.) There is an FSM course given by F. Varela. (What will follow in a moment is not it!) 44

45 Why FSM? The DCS of the LHC experiments consists of a large variety of complex devices and technologies The FSM is the tool that: Hides the complexity of the system build abstraction of (eg) a detector understandable for non-expert Summarizes the conditions of the many devices in the DCS into a single overall state (tree) Allows the shifter to operate the detector with a few mouse-clicks

46 CU Example FSM DU DCS Vertex HV LV HV LV Tracker Cooling Cooling HV HV Gas Gas Muon Cooling Cooling HV HV Commands go down 1 level at a time; States propagate up Strict hierarchy Nodes have only 1 parent No horizontal lines LV LV Gas Gas Commands States & Alarms 46

47 Original aim of the Exercise To show that using FSMs is really rather simple, (conceptually at least!) As a warning about the implementation to emphasise the great level of detail that is required and how, unfortunately, the detail can rapidly overwhelm people Hence, why there is an experts course! Each subdetector will need one or two FSM experts, but no more. 47

48 Aim of the demo See an FSM in action If you really want to recreate and play with the demo for yourself, by all means do so, but wait until this weekend This demo is new; no additional documentation material available yet. Was a handout: Introductory Demonstration for the Finite State Machine Component in CourseMaterialsForStudents/Components/FsmSwDemo/fsmDemoInstructions.pdf (it is out of date)... 48

49 FSM Demo: tree architecture Subdet Saleve Jura... tube12 tube02 channel 001 channel 000 channel 012 channel 01 channel 005 channel 003 channel 002 channel 001 channel 000 tube04... tube12 CAEN/crate1/board01 CAEN/crate1/board00... tube05... channel 012 tube04 tube03... channel 01 tube02 tube01 tube05 LV channel 005 tube03 HV... channel 003 tube01 LV channel 002 HV 49

50 FSM demo: setup I Install the component (from ~/workspace) fwjcopcoursefsmdemo 50

51 FSM demo: setup II Start the DIM DNS process. In your experiment, there is a central one already running... Open a terminal and execute ~/PVSS_projects/fwComponents_ /bin/Dns (pay attention to capital D in the executable name!) Leave the terminal open 51

52 FSM demo: setup III Tell the FSM in your project to use your DIM DNS: localhost 52

53 FSM demo: setup IV Generate the FSM: Configuration mode FSM tab Select top of tree Right click-> Generate all FSMs

54 FSM demo: setup V Start the FSM: Operation mode FSM tab Click Start/Restart All

55 FSM demo: setup VI Connect the CAEN simulator Panel already open Shown Own System List all CAEN channels Select all the channels (Shift-Click, Ctrl-Click!) Click Connect Selected

56 FSM demo: setup VII Open the FSM operation panel for the top node and take control of the Subdet tree.

57 FSM demo Drill-down in the tree with doubleclick to find root-cause of a problem

58 FSM demo Convince yourself that the channel really tripped: use logical view

59 FSM demo Note alarm is masked (disabled) on trip. FSM reported the trip anywa it is a parallel supervision method. Enable the alarm now

60 FSM demo Recover the trip: switch on the channel again (do it in the CAEN simulator)

61 FSM demo Now trip the same channel (using CAEN simulator) yet this time we recover it using FSM

62 FSM demo Now select 10 channels in simulator and trip them (simulate a large trip of a part of detector) And recover the complete HV system with one command

63 FSM demo Disaster scenario: trip all channels And then recover the complete subdetector or switch it off: RESET, switch it on: CONFIGURE ` Subdet Saleve Jura...

64 FSM Imagine... Each of you implement a subdetector We form a distributed system with a Central DCS sitting at the top and commanding all subdetectors => this is what is shown in the FSM Course We could operate the detector from the top, or share (delegate the control) of some of them to expets.... or really operate hand-in-hand in parallel without conflict It is a bit too difficult to demo this in this course

65 Need to learn more about FSM? Go on the FSM course! Wait at least a couple of months though, to get really familiar with WinCC-OA first really! 65

66 FwAccessControl Aim: protect from accidental operation/mistake Assure proper tracability of action Not: Protection against malicious attacks Cybersecurity How Authentication (login) -> CERN accountts Authorizations: Enable/Disable UI elements Integrate with builtin WinCC OA mechanism Make it easier for you (panel developers) Do not reinvent the wheel 66

67 What do we protect Access right = domain:privilege concept Relatively good abstract model: Object and actions on it defining levels of access For instance a filesystem: file readable/writable/executable Yet made more abstract: Object => more generaly a Domain Could be any entity, physical, organisational, virtual Privilege Level of access (eg. action) related to this domain Combined Domain:Privilege = Access Right eg. HV:OnOff, HV:VoltageScan, HV:FirmwareUpgrade, Accelerator:Monitor, Detector:RampUp. Detector:Shutdown 67

68 Who has access right... In the end: users are the actors! Not easy to configure for large organisation many users may need the same privileges, and lots of them => use Role Based Access Control concept (not to mistake with RBAC project for accelerator equipment by CERN BE/CO) or to make it simpler: groups (again, like in a filesystem) Two complementary/overlapping (!) concepts Group: set of users performing similar actions Role: set of access rights required for certain actions 68

69 Who has access right Example may be clearer... Users joe, jane, john need to be shifters in my experiment To do that they need: ECAL_HV:OnOff, ECAL_LV:OnOff, HCAL:Operate, Tracker:operate At the same time joe, alice are experts in the ECAL HV system, called when detector tuning is performed; they may need ECAL_HV:VoltageScan, ECAL_HV:SetThresholds We create two roles: ShifterRole, EcalHvExpertRole And two groups: Operators, EcalExpertsOnCall These could be CERN Egroups Most generic model: we assign roles to groups May be simplified (groups and roles colapsed), sometimes leads to confusion Note: joe has two roles; alice has insufficient right for being a shifter 69

70 Mechanisms WinCC OA concepts of Users, Groups, Areas (domains), Privilege levels DP Authorization (protection): not recommended Create/Delete DP/DPType/Alias protection Cumbersome to use and configure (esp. in dist systems) FwAccessControl reuses these builtin mechanisms Configuration and synchronization tools, panels Integration with CERN infrastructure (user accounts, egroups) Simple way to integrate Access Control into your panels 70

71 Aim of excercise Implement Access Control in a simple panel Protect 4 buttons (enable/disable) depending on who logs in Similar solution is in... in the fwaccesscontrol component: fwaccesscontrol/fwaccesscontrol_demo.pnl 71

72 Building blocks (I) Create and configure domain/privileges, groups, users Through fwaccesscontrol configuration panels: GEDI > JCOP Framework > Access Control > AC Toolbar right-click to pop up the menu > Administration In the demo panel this is done using scripts! Domain: Test Privilege names: Monitor, Control, Debug, Modify, Administer Groups: Operators, Administrators, Experts Users: add two users Operators: Test:Monitor, Test:Control Administrators: Test:Monitor, Test:Administer Experts: Test:Monitor, Test:Control, Test:Debug, Test:Modify 72

73 Building blocks (II) 4 buttons: MONITOR, CONTROL, ADMINISTER, MODIFY Should be protected with corresponding access rights A callback function in your panel Called whenever user logs in/out; put it in the scope lib void MyAccessControlCB(string s1, string s2) { } Should check the privileges of the current user void fwaccesscontrol_isgranted( Domain:Priv, bool &isgranted, dyn_string &exceptioninfo) Enable/disable buttons accordingly BUTTON.enabled=true; // or false Registered/activated in the Initialize script of the panel fwaccesscontrol_setuppanel( MyAccessControlCB, exceptioninfo); 73

74 Use of CERN credentials Configure the authentication against CERN AD Server (as root) GEDI>JCOP Fw> Access Control > Setup Authentication: Mode: LDAP LDAP Server: cerndc.cern.ch (on TechNet: cerntn.cern.ch) LDAP AuthMethod: DIGEST-MD5 74

75 Use of CERN credentials (II) Create users in WinCC OA, with names matching the CERN user names Option 1: do it manually (do it!) Don't forget to include in some group to get the login access rights Option 2: Egroup-synchronization Expert option; Append a new Control Manager running (encrypted) script: fwaccesscontrol/fwaccesscontrol_egroupsync.ctc You may sync individual groups Or you may even sync complete access control configuration (domains, privs, groups, roles, egroup hierarchies, etc) 75

76 Default user in the config file By default in WinCC OA 3.15 GEDI starts as root Any other UI start in logged out state ( undefined user ) ->leads to many problems eg. fwtrending cannot create its datapoints It was not like that in WinCC OA 3.11! Wirg JCOP Fw we fix it and try to define default user (root or operator) at fwcore installation time. 76

77 Default user in the config file You should review/tune the setting Definition in the [general] section of the config file username= root password= WinCC OA root user has all admin rights. OK for development (all permissions granted) not acceptable for production: Change it to a generic, unprivileged account e.g. in UNICOS: monitor, allowing to visualize only make sure the password is empty for this account (or WinCC OA will refuse to start the UI) 77

78

79 How do I make a component? Not a rocket science really! Collection of panels, colordbs, scripts, libs, binaries, DPL files, help Accompanied by Component Definition XML file Component name, version, list of files, etc have a look at fwgeneral.xml in your component folder Specials: PreInit and PostInstall scripts Config file fragments Subcomponents Dependencies (other components, WinCC OA version) Utility functions: delivered by fwinstallation library 79

80 How do I make a component? Recommendations: Remember: you often share components with others Keep the code in a version-control system (SVN, git...) Keep the versions unique Keep the code clean and easy to read Carefully adjust dependencies whenever needed Do use #uses to load the libraries and Ctrl extensions TEST IT! A new version of component whenever you change anything By installing in a project Unit tests? We have a tool to do this 80

Copying projects Making your own component Other WinCC-OA facilities we ve not mentioned, but that you will see in the Help: Panel Topology Complex graphic objects Power configs Archiving/Compression Authorisation Where to get help on Monday morning next week! 88

89 Backing Up your Development Project Creating projects on network drives is bad idea Lots of network traffic (WinCC OA writes constantly) UNC paths on Windows do not work. Use your local drive. Cern IT does not back up your local drive! Cern IT does not back up your local drive! Cern IT does not back up your local drive! Remember, you re building on a foundation of cheap disks. The software is very tolerant to power cuts, but in the last resort, who knows what your disk will do? For a dev project, copy the entire Project Tree DO STOP the project Or your copy of RAIMA DB will be corrupted... or use the Online Backup 89

90 Backing Up a Running System Back up the History DB. (Oracle?) RAIMA- Database pending Alerts HistoryDB Last Values Value-History Alert-History DP-Types, DP s, Configs Flat file DB: It s in the FAQ 90

93 Copying projects Ever wanted to take your projects home with you after a course? You can copy the whole project tree. When you get home, you place it in a folder and click on the Register Project button in PA. Use same pathname for folder as before (otherwise you ll need to edit the config file.) 93

94 But the whole tree is big! Contains the log files, the value archive files (they re big!), configuration history DB. You don t really want whole project at all! Rather All Panels All Scripts All DPT/DP and their config (eg alert) definitions 94

95 Panels Copy them. Or them. Look at one it s text! Same panel text is understood by WinCC-OA on Linux and WinCC-OA on Windows. You can draw a panel on your preferred platform. Run it on either All Panels All Scripts All DPT/DP and their config (eg alert) definitions 95

96 Scripts Already said you can use any text editor. They re text. All Panels All Scripts All DPT/DP and their config (eg alert) definitions 96

97 DPTs and DPs Are in the database We need some DB tools to take these definitions home with us. All Panels All Scripts All DPT/DP and their config (eg alert) definitions 97

98 Ascii Manager - I Special manager you run as required. Exports DPT/DPs/Configs from the database into a text file. Can copy or the text file to another machine. Use same Ascii Manager to import the file again into a different project. 98

99 Ascii Manager - II Invoke Ascii Manager either from the System Management panel: Or via GEDI > SysMgm > Database > Ascii Manager 99

104 Fw Packager Concerning your own development, how will you make it available to your colleagues? You can package your stuff as a component (in the Fw sense) using the Fw Packager 104

105 Fw Advanced Course described the Packager. But this course is no longer available. (Why?) Nevertheless all the Advanced Course materials are still on the web at: +Service+Training+Advanced+Course Advanced course topics: Packaging Components (pps) fwdim Component (pps) CNIC Awareness and Tools (pps) Alarm Handling (pps) Integration of new Device Types (pps) Configuration Database Tool (pdf) Access Control (pdf) Using Access Control in the FSM (pps) Using Configuration Database in the FSM (pps) 105

106 Ragbag of other items that we don t cover in detail, but which I want to mention at least briefly 106

107 Fun (useful) Catalog items Open the ETM catalog e.g. Gedi > View > catalogs > C:\Siemens\Automation\ WinCC_OA\3.xx 107

108 STD_Simulators Number generators Random number generator Ramping (sawtooth) number generator Sine wave number generator Drag and drop one onto your canvas. (Demo?) 108

109 A Trap I fell into Your distributed project from Wednesday connects to my teaching machine here. Now you know how, I m about to suggest you copy your project to take back to your office. When you run it in your office, it will again connect to my teaching machine right here and if I m teaching, I ll get some surprises. 109

110 Spare my blushes Please edit your config file now. Go on. Just for me. Please? Comment out the client connection line(s) [dist] # distpeer = "pchret2501"

111 Taking your files with you You are currently logged in as trn25nn You need to be able to write your files to somewhere that you can read them back from (when logged in as yourself) from your office, next week. A USB stick is fine! (in the training rooms anyway.) SCP for the Linux guys (AFS scratch area on LXPLUS) No stick? The Cern Computer Centre allows you to request a writable area on DFS. (Scratch space) You may upload to your DFS space (webdfs.cern.ch) 111

112 More Framework Tools and Devices The JCOP Framework is a large collection of tools and devices many more than we have had time to play with. This week, I ve shown you some examples and the philosophy behind them. Before you start to implement pretty much anything, first consult the full Framework list at 112

113 XML Parsing XML is a standardised way of specifying the structure of information and the values therein. Used widely in industry. Historically, many people have written their own XML generators and parsers. Please don t! The JCOP Framework supplies routines (built on ETM s CTRL library to help you parse and manipulate XML. Please use the fwxml package. 113

114 Authorization A feature or a bug? Protects your precious equipment from your helpful colleagues, never mind from hackers! Protects you from yourself! (Role.) Fw Access Control component: Access Control Course notes: +Service+Training+Advanced+Course includes info on Access Control in FSM. 114

115 Protecting your hardware Demo program showing how to restrict input (pv_range) CourseMaterialsForStudents\Components\Solutions\panels\Sol utions\canonlyenteranumberwithinagivenrange.pnl 115

116 FAQ: What have I forgotten? A checklist for production systems 116

117 Emergency Mode If you run low on disk space or low on memory, WinCC-OA will enter Emergency Mode. Alarm. Restricted functionality designed to put off the awful moment when everything stops and give you time to do something before it does all fall over. ( _UI_110) FAQ: My disk is nearly full! What can I do? We don t recommend you wait until that point to decide on a storage policy! Really! You might be surprised at the number of people who do wait till then 117

118 What else have I not covered? Panel Topology: ETM themselves noticed that many of the systems they implemented in WinCC-OA had a very similar look and feel. They came up with some generic panels, including standard layout and inter-panel navigation buttons. Not used at CERN, unfortunately not compatible with the Fw. You may see it in the documentation, but it is to be avoided. 118

119 Complex Graphics Objects You should experiment yourselves with Combobox/cascade objects (a la menu items) Radio Buttons Check boxes Table Tab (tabbed display); nasty to use Embedded module Clock Etc. etc. Other objects in the graphic catalogue. 119

120 Power Configs WinCC-OA provides a mass parameterization facility called Power Configs. If you are using JCOP or Unicos Frameworks though, steer away from these to avoid conflicts. 120
