The Freelance process level
A Freelance system can consist of between one and several AC 700F and AC 800F controllers and can be extended with different types of I/O units. You have the option of configuring your system either standard or fully redundant. AC 700F is meant for applications with up to 300 I/O signals per AC 700F controller. This PLC-like controller comes with a very small footprint. S700 direct I/O modules can be directly plugged to the controller module.
