Hi at all.

First I am new to PLC. I just have skills in "normal" programming.
I try to implement a "is multiple of" PLC. See "4DIAC.png".

A F_MOD gets its dividend by an upcounter and has a fixed divisor.
How ever the F_MOD does no action even if the upcounter has values as you can see in the watches.

So whats wrong?

The NA in the monitoring indicates that the block could not deployed to your runtime. Do you get any error in the Deployment Console (you can get it via: Window -> show view -> other and search for it)
Do you have the IEC 61131-3 lib compiled into your 4diac FORTE?

Ok, thanks.

It says:
<!-- 127.0.0.1:61499: EMB_RES -->
<Request Action="CREATE" ID="11">
  <Connection Destination="F_MOD.REQ" Source="E_CTU.CUO"/>
</Request>

<Response ID="11" Reason="NO_SUCH_OBJECT"/>


<!-- 127.0.0.1:61499: EMB_RES -->
<Request Action="CREATE" ID="12">
  <Connection Destination="F_MOD.IN1" Source="E_CTU.CV"/>
</Request>

<Response ID="12" Reason="NO_SUCH_OBJECT"/>


I 'll try to debug this.

could it be that above is a NO_SUCH_TYPE error?

No.
I use forte binary downloaded from the homepage running on Ubuntu 20.04 LTS.
Alternative I build the variant with CMake for PikeOS and run it on a QEMU-Arm-v7 emulated target with usermode network. Port 61499 was to the targets forte port.
So both, Ubuntu and PikeOS, where reachable via 127.0.0.1:61499.
The complet log of the deployment console is attached.

"Problems and Warnings" View is empty.

This is the STDOUT print of PikeOS which was similar to Ubuntu:
INFO: T#51123721770: FORTE starting
INFO: T#51263721770: FORTE is up and running
INFO: T#51283721770: Using provided bootfile location set in CMake: forte.fboot
INFO: T#51303721770: Boot file forte.fboot could not be opened. Skipping...

As expected in both cases you get an unsupported type error. this means that the FB type of F_MOD is not available in your runtime. You need to enable the IEC 61131-3 module where this FB is contained in.

Hi,

thanks to the hint. I rebuild it with enable "FORTE_MODULE_IEC61131" within CMake GUI.

On Ubuntu it does run fine.
On PikeOS the runtime reports:
ERROR: T#51289337000: Error could not create the thread! Unknown error: 0
ERROR: T#51309337000: Error could not create the thread!

on deploying. But that's a PikeOS problem I guess.

I fear yes this is a PikeOS problem. The PikeOS support was implemented by the PikeOS people so I have no knowledge what the problem could be here.

I refactored "arch/pikeos_posix/forte_thread.cpp". Now the error is
ERROR: T#132893716700: Error could not create the thread! Operation not permitted


I'll give feedback if I have it running on PikeOS.

PikeOS have strict RAM configurations for each process.
On deploying it runs out of RAM. Just increase RAM Size in the PikeOS Integration Project for each forte process, if you have compiled forte with more than just the base modules:

index.php/fa/40337/0/
