Post by andrej on POU - Access to runtime ^{CODESYS Forge talk (Post)}
Hello all, when creating a POU, the Codesys IDE allows the setting "Enable System Call" (in the Settings, Property -> Build), see picture. The name suggest, that runtime functionalities i.e. functions of codesyscontrol such as "stop plc" etc. can be directly called. I tried various approches without success, the following does, unsurprisingly not work. FUNCTION accessRTE: BOOL; ****************************** codesyscontrol.stop(); Can you please tell me how I can make a system call to codesyscontrol from a POU. Or could you provide me with a use case for this setting. Many thanks for your feedback and kind regards Andrej

Post by s1ack on Wago PFC200 Ethernet / IoDrvEthernet Issue? ^{CODESYS Forge talk (Post)}
I changed the interfaces to br0 & br1 as they are designated on the Wago PFC200. That issue is resoved. However, on site I have very high system cpu usage, system as in Linux. Presently it is not known why - my bench system does not exhibit such high system usage. In the past this was due to IGMP network traffic every 250uSec from synchronized inverters.

Post by schnepper on Error building Extension SDK Linux code ^{CODESYS Forge talk (Post)}
I'm installed the CODESYS Control for Linux SL package and am trying to use the Extension API to call a simple C function. When I get to the step to run "make all" on the Linux machine, I get the error: build interface header: out/CmpFirstTestItf.h from CmpFirstTestItf.m4 ERROR: This functionname does not contain _cext (this is mandatory, see help for details): DEF_API(void',CDECL',external_struct__fb_init',(external_struct_fb_init_struct *p)',1,0x1F77E075,0x00000001) Why does "Generate Runtime System Files" create a function that does not have cext in the name? What am I missing?

What does this message mean, in the Errors/Messages box? "[ERROR] MyProjectName: No Offline Help installed" In CDS23, I used to be able to select a system function with the mouse, and press F1. Help and description would popup. How do I get so-called On-line Help installed?
