Do you like SFC? I don't. Do you use your own programming patterns? Open my web page and let me know what you think about my programming patterns. PLC programming patterns

With RSLogix5000 you can save a program as XML and you can open it from XML file. You can find any rung of your ladder logic program as a string. A visio file you can save as XML too. From this file you can read a flow chart (a transition Tx from a state Sy to state Sz). When you have this info about your flow chart you can write a ladder logic or Structured Text program (a set of lines) into your RSLogix5000 xml. If you need more info please let me know. Zygmunt

I have the idea. Mostly we document PLC projects using Visio. I mean states - transitions - alarms. Let say your PLC is IEC 61131-3 compatible or you can save a program (export - import or save as) as XML file. It is possible to create a single PLC program module as a Visio page template (a flow chart with a data). Then you can build any complicated program as a set of Visio pages??? This Visio page template can be use to program all PLCs which agree with the condition above. What do you think about my idea? For today I know how to for RSlogix5000, Step7, CX-0ne, Beckhoff and Wago. ZM

FX1nc and FX2n-232IF When I am sending data #28 b3=1 but #29 b0=1 It means : Status says Error but Error buffer says NO ERROR. My short program is based on a sample from a manual for this module. Any idea, please let me know... Ziggy

During this weekend I will try to post it. It is posted as a Demo.zip in OMRON - Demo Software ... let me know what you think about it!

Omron Function Blocks ST I have an utility which converts a Visio flow chart to txt file - which you can copy - paste into FB. Transitions - FB inputs, States - FB oututs. LL only to define transitions (based on inputs or internals) and outputs (based on outputs or internals). It works better than SFC! - less limitations! Any questions - please let me know.

I have an utility in C# which converts Visio vsd to txt. This txt file can be copy paste into Omron Function Block ST. It works very good. You can debug only your flow chart. One click and your FB ST is updated too.

I have a C# program which converts vsd to txt file. It is based on Visio SDK. You can make a change in your Visio flow chart and save it. Use my utility which will update your txt file. Copy and paste into FB - done. I am using LL to define transitions and outputs based on states.

The easy way to program OMRON PLC using Function Blocks. From Visio *.vsd to *.txt file. Then copy and paste into Function Block ST type body. Any corrections to a Visio flow chart - one click and *.txt is corrected too. From the documentation to the LL. It works!

Presently I am using Visio x.vsd file to create x.txt file which I can copy and paste into FB - Structured Text. In LL the FB has an input channel for transitions and an output channel for actual states. LL defines all transitions and real outputs and interconnections between Fbs - what can be done building another flow chart -> FB. This approach should works for any PLC with FB!

Yes, I think about a utility which based on Visio file x.vsd can produce for you a LL code. Presently I am testing this type application for OMRON CJ1G and works perfect. You can make a small correction to your flow chart and your LL is updated automatically.
