Hi Everyone, Learning the ropes of SoMachine V4.2 (coming from Arduino and Ucontrollers), I am using a Sequiental step style program and I am receiving 4 error messages. I'm trying to understand why it won't compile. POU for implicit check is missing. It is recommend to add the POU. C0032: Cannot convert type "IeSFc.SFCStepType(iesfc,3.4.2.0 (systen))'to type BOOL "Same error for a different ladder (the output of ladder rung hits the transition step, the transition is a bool which kicks off the beginning of another ladder rung). C0032: Cannot convert type BOOL to "IeSFc.SFCStepType(iesfc,3.4.2.0 (systen)) Are these two different "data" types? Thanks in advance!

Hi Everyone, I just finished my first project and I don't know how to make comments next to my "actions". I'm using SFC. I'm use to writing C code so this is so different!

"Ladder Logic" internal contact set-up
MikeOrsini87 posted a topic in Modicon / Telemecanique / Schneider Electric
Hi Everyone, I'm working on my first PLC program and I have gotten my hands on some ladder logic I'm trying to duplicate. I'm using SoMachine 4.1 and have started a new Ladder Logic diagram POU. I'm curious on how do I create internal contacts. EXAMPLE: 24v--------l START BUTTON l----------------( COIL A)----- --------------l COIL A CONTACT 1; attached to a real output, solenoid valvel-------------l COIL A INTERNAL CONTACT TO CLOSE l---------------- Are there standards for numbering and labeling? I'm seeing L and U inside coil contacts. Does this have an underlying meaning according to standard? Is there a RTO function inside SoMachine 4.1- 1 reply

Hi Everyone! Where are my experts? I am undertaking a project at work. The project contains analog style motor positioning circuits (operational amplifiers, integrators, and other PI elements). Not that this is relevant to the post yet ;) .It's my first PLC project ever! I am using the Schneider M258 with SoMachine 4.1 The PLC is talking to SoMachine via Ethernet (obviously I have a router between the PLC and my pc).I can Login and run the first POU I created. It's a simple And logic circuit for now. I have a co worker (c programmer) agreeing to help me pass data from my PLC to a browser screen. Although he's not familiar with PLC he's quite skilled writing code. He has wrote a Modbus protocol which allows him to interpret Modbus commands on his desktop. 1) Do I Need any special hardware to pass the data out of the PLC into the Router then into his browser. 2) As a trial can I send him MODBUS commands regarding my AND circuit? 3) How do I create such a command? 4) Is it possible for him to send me Modbus commands to change variables inside my program? 5) Are there web browser "plug-ins" for this idea? Thanks for reading and hopefully all of you can help me answer some of these questions.
