The AC 700F controller has a compact design and a high signal density of S700I/O.. S700 I/O module can be directly inserted into CPU module or used as remote I/O through PROFIBUS, and up to eight modules can be connected to a controller. Through the pluggable SD card, AC 700F provides flexible controller backup and firmware update functions.

The controller adopts modular design, and its basic components include different types of terminal units, which are suitable for CPU module and S700 I/O module. Two types of terminal units, screw type and spring type, are provided. The module can be easily inserted into the terminal units, connected with each other and installed on DIN guide rail as a whole.

AC 700F controller has CE, GL, UL, ISO 9001 and other certifications. In terms of technical performance, the communication speed between CPU and the direct S700 I/O module is extremely fast, which can realize 2 ms I/O scanning time, and each channel can realize short circuit and disconnection detection. In terms of environmental adaptation, the working temperature range is 0 C to 60 C..

The central processing unit PM 783F is equipped with a high-performance processor, which supports fast cycle times. Built-in 100 Mbit/s Ethernet connection is used for communication between controller, operation station and engineering tools. Two serial interfaces complement connectivity, one for Modbus communication and the other for diagnosis. For complex applications, eight cyclic and priority-driven tasks and a cyclic PLC task that runs as fast as possible can be configured to realize multi-task processing, balance CPU load and minimize project resource requirements.

The display screen in front of the module can directly display the status and diagnosis information, and the controller can be locked by keys to prevent the application and firmware from downloading and improve the security. The locking status is clear at a glance.

In addition, as the DP master station, the PROFIBUS module CI 773F supports the DP-V0/V1 protocol, and the speed can reach 12 mbit/s. It needs to be connected to PM 904F, PM 902F, PM 901F or AC 700F with TB 711F terminal base through coupler bus slot. Other accessories include serial cables for diagnosis, batteries for RAM buffering, virtual coupler modules for protecting unused coupler slots, and accessories for backplane installation.

The AC 700F controller comes in a really small footprint and high signal density of S700 I/O.   The S700 I/O modules are directly plugged to   the CPU module or can be used as remote I/O   via PROFIBUS. A maximum of eight modules can be connected to one controller. AC 700F offers expanded flexibility via a pluggable SD card for controller backup and firmware update.

Hardware and certificates

AC 700F comes with a modular design. The base elements are different types of terminal units, for the CPU module and for S700 I/O modules. Both, screw type and spring type terminal units are available. The modules can be easily plugged to the terminal units and then the terminal units can be plugged one to the other. The entire controller is then mounted on a DIN rail.

Certificates The AC 700F controller has the following   certificates:
 • CE, GL, UL, ISO 9001.
Technical data The CPU and the direct S700 I/O modules com municate very fast. I/O scan times of 2 ms are possible. Short circuit and line break detection can be realized for each channel.
Environmental conditions The temperature range of AC 700F and S700 I/O extends from 0 °C to 60 °C / 32-140 °F.

Central processing unit PM 783F

PM 783F Central Processing Unit (2 MB) Without operating system. The operating system has to be loaded during software installation.   Needs external 24 VDC power supply. Software version 2013 SP1 RU04, 2016 SP1 RU03 or higher is mandatory. For details, refer to the Freelance AC 700F Compatibility Matrix (2PAA106303D0002 C). Terminal Base TB 711F and Battery TA521 are not included

The Central Processing Unit (CPU) module is equipped with a high-performance processor for fast loop cycle times. It comes with on-board 100 Mbit/s Ethernet network connection used for communication between controllers, operator stations, and engineering tool. Two serial line   interfaces complement the connectivity. One interface can be used for Modbus.

communication, while the other is used for diag nostics. 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 the minimum.

The small front panel display shows status and   diagnostic information directly at the module. 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.
