Linux as a Soft-PLC

One of the most interesting applications for an Embedded system is to use it as a Soft-PLC. Since many years Linux has several programs that could be used for a Soft-PLC:
  • ClassicLadder, which is C-based and relies only on Ladder (KOP);
  • MBLogic, which is Python-based and relies on IL and Ladder;
  • Beremiz, which is also C-based and includes all the IEC-61131-3 languages.
MBLogic and Beremiz also include webservers. This allows to use them as remote HMIs.
