  3BDH000364R0002

• ABB Type Designation:

  PM 783F

• Catalog Description:

  PM 783F CPU Module

• Long Description:

  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 complete the connectivity. One interface can be used for Modbus communication, while the other is used for diagnostics. The CPU has 10 MB of memory of which 2 MB are battery backed up. 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. 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. S700 I/O modules can be 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. 3rd party I/O‘s can be connected via a MODBUS ASCII / RTU, IEC 60870-5-101 Telecontrol protocol or via PROFIBUS. The CPU and the local S700 I/O modules communicate very fast. I/O scan times of 2 ms are possible. Short circuit and line break detection is realized for each channel.
