I'm using WAGO PFC 750-8202
like infinite loop, negative square root
hm.. in CODESYS V2.3 there is only the watchdog (on the task) which you could activate to prevent endless loop detection
sure you could add the implicit check functions to check for 'Division by zero' or check bounds etc... check the help for this.
Sure in CODESYS V3 or eCOCKPIT there are additional mechanism , plcload supervision (for the whole plc not only for one Task a watchdog)
impilcit check functions etc
Anyway I would recommend to use CODESYS V3 no matter if you use CODESYS V3 or eCockbit.
There are so many Features available - which are from my Point of view mandatory to have - plc logger - html5 webvisu and many more
- all Ethernet based fieldbus / ethercat ..
