This is the smallest Freelance CPU that typically supports up to 300 I/Os. It optionally can be equipped with 8 direct I/O modules and one Profibus Interface module and supports Modbus TCP. Two serial line interfaces complement the connectivity. One interface can be used for Modbus communication, while the other is used for diagnosis.For demanding applications, eight cyclic and priority-driven tasks with adjustable cycle time can be configured, as well as a cyclic PLC-type task, which runs as fast as possible. This multi-tasking scenario enables engineers to design applications that reflect all demands of process control, while at the same time balancing the CPU load. This keeps the resources needed in a project at a minimum. The small front panel display shows status and diagnostic information.
Furthermore, you can lock the controller via the keys. This means the controller can be blocked for downloads of application and firmware to enhance security. The status, if the controller is locked or unlocked, is shown on the display.
