Hi there I'm an embedded software engineer mostly programming C/C++ in Linux and have very little knowledge of the PLC environment.  Recently my attention was diverted towards integrating C/C++ (Linux software) into PLC and then presumably as a function block which is supported with something called PLCOpen. Is that right ? How is multithread support in PLC in general ? and/or with the these function blocks or what ever might become instead when integrating/porting C/C++ code into PLC.  The current situation is purely embedded Linux environment with open-source 3rd party userland that our code relies heavily on. How feasible is to port such environment over to PLC (given that the system supports it) ? I've been looking into B&R Automation Studio 4 and having a hard time to establish concrete feeling on how difficult/easy it is to port the code.  Hope anyone can give me a slight insight into this.  Kind regards Einar
