Introduction

Straton is a software PLC runtime developed by COPALP, used to develop under IEC61131 languages. It's composed of:

• a runtime running on the target (APF) and interpreting your automation process
• a workbench (only available on Window$) that let you design your process and load it to the target through a network interface

Straton runtime on ARMadeus

To use straton runtime under armadeus simply select it under menuconfig (make menuconfig):

Package Selection for the target  --->
	Armadeus specific tools/utilities  --->
	...
	[*] straton  IEC-61131-3 environment 
	...
	[*] straton_ios
	...

Straton runtime is not an open source software, to use it under ARMadeus System 3 options are available on straton IEC-61131-3 environment option:

• straton_dev: If you have a VMTK license provided by COPALP select this option. You will have to set the code path directory under straton development directory option :

Package Selection for the target  --->
	Armadeus specific tools/utilities  --->
	...
	[*] straton  IEC-61131-3 environment 
	(/home/runtime) straton development directory
	[*] straton_ios
	...

• straton_bin: If you have a runtime license provided by COPALP select this option. You will have to copy the tarball under your downloads/ directory.
• straton_demo: If you don't have any license and you just want to test it select this option. Demo runtime binary will be automatically installed under rootfs .

Straton Workbench on Windows

First download the workbench from COPALP website here : [1]

Then install it under your windows as copalp explains it.

To use ARMadeus Input/Output, you have to use a specific profile named armadeus.XL5 which can be found in target/packages/straton_ios/. Copy this file on your windows system then import it under straton library.

straton library -> tools -> import

a simple program with Workbench

To illustrate straton working, we will do a simple program that light the led when we push the button.

First launch straton workbench then create a project :

File -> add new project

Give a name then give the runtime IP address+port and protocol. For example :

ip: 192.168.0.10:1100
protocole: T5 runtime

Terminate, then double-clic on main program icon in the tree on the left of straton workbench.

Add two globals variables named button and led by right-clicking on global variable on the right of straton workbench.

Configure these variables to be synchronized with your apf board profile by right clicking on each variables add lauching property menu. Under property menu select the right profile. And select the right type (button for button and led for led).

Once your variables are correctly configured, simply drag'n'drop it under the main window and connect it with a wire. You must obtain this :

figure 1 - Really complex program in straton to bink a led

run the program

To run our really complex program, the first thing to do is to run straton on target :

# straton
T5 runtime - Linux Multithreaded - Embedded HMI - Jun 23 2011
*** Straton is running in demo mode ***
V1.0/8.2.110124 - 2010 - (c) copalp
 2010, 2011 - ARMadeus Systems

Ready - Press CTRL+C to exit.

Initialize ios
Profile used : APF27

Then on the workbench click on download then execute. You can push the button and watch the led blinking.

Troubleshooting

Runtime can print network errors sometimes :

Network Error:Broken pipe detected

It's a known error but not fatal for working process.

Modify I/O profiles

On apf27 and apf51 only a led and a button are presents, it's possible to improve IO using straton_ios library. Ask fabien.marteau@armadeus.com to write this tutorial. FabienM 13:06, 24 June 2011 (UTC)
