Combitech söker PLC programmer, för uppdrag hos kund Beskrivning PLC programmer, nivå 2 PLC programmer for development of power monitoring and control software in structured text. In short: We are looking for a PLC programmer for development of control software to be deployed on a series of power monitoring systems. The systems are based on Beckhoff’s Twincat 3 software suite and are using their CX and EL series hardware for sensing and control. Focus for software development shall be robustness, easy reconfiguration to represent future hardware changes and expansion of the software, all while being well documented. The target systems: The software to be developed will be deployed on a series of power monitoring systems with a shared common architecture. These monitoring systems are part of larger test setups and serve to protect a device under test by intercepting its power supply and breaking the circuit if unfavorable conditions would occur. Examples of such conditions are over-/undervoltage, excessive current consumption, insufficient cooling. Each system is based on a Beckhoff PLC running Twincat 3. Associated with the PLC are several Beckhoff EL- series terminals for I/O and control purposes. The exact configuration of terminals will vary dependent on the system but can be split into functional blocks each handling a specific task such as monitoring a power supply channel of a specific voltage or reading external sensors. In addition to monitoring power and external sensors, the system will also be connected to the larger test setup and must therefore be controllable via remote a remote interface such as ethernet. The Assignment: Given the monitoring system architecture, hardware design, and a detailed functional description, we are looking for a PLC software developer that can translate our requirements into well-documented, functional and robust software to be deployed on the hardware systems. Intended for deployment on critical protective systems, developed software must be robust and able to handle all foreseeable system faults and errors without issue. Our expectations: Programming of the Twincat 3 system shall be performed using TwinCAT XAE and code shall be written in structured text (ST). Work shall be performed on site for access to hardware and easy, open communication with the development team. Developed code shall be well documented and well structured such that another developer can continue development at a later date. Developed code shall be modular to represent the functional hardware blocks with easy construction of new system configurations. Developed code shall be robust and be able to gracefully handle foreseeable faults and system errors. Requirements: Basic electrical knowledge for understanding monitoring systems. Experience of PLC programming and development of robust programs in structured text. Preferably experienced with programming for Twincat 3 specifically. Experience in software architecture for construction of a framework for modular software where functionality can be modified and added without affecting the core structure.
