ABB DCS PM856 CPU ABB AC800M PLC AC 800M Controller
ABB AC 800M PM856 Controller
The ABB AC 800M PM856 controller is a family of rail-mounted modules, consisting of AC 800M CPUs, communication modules, power supply modules and various accessories. Several CPU modules are available that vary in terms of processing power, memory size, SIL-rating, and redundancy support.
Each AC 800M PM856 CPU module is equipped with two Ethernet ports for communication with other controllers and for interaction with operators, engineers, managers, and higher level applications. A Flash memory card can be inserted into a slot in the AC 800M PM856 CPU module to store the application and data.
The connectivity and expansion options make the AC 800M PM856 exceptionally open and scalable, that is, easy to connect to the surrounding world of supervisory systems and intelligent devices of all kinds – and adaptable to changing requirements as the process it controls changes or expands.
AC 800M High Integrity Controller
The ABB AC 800M PM856 High-Integrity offers an IEC 61508 and TÜV-certified control environment for combining safety and business critical process control in one controller unit without sacrificing the safety integrity.
The ABB AC 800M HI is certified to comply with the requirements of:
- Requirement Class AK 1 – 4 according to DIN V 19250/DIN V VDE 0801
- Safety Integrity Level 1 – 3 according to IEC 61508
- Category 1 – 3 according to EN 954-1
The ABB AC 800M PM856 controller can be configured with both Compact Control Builder and ABB 800xA control builder.
When configured with the Compact Control Builder the ABB AC 800M is open to participate in any kind of control solution.
When configured with the ABB 800xA PM856 control builder AC 800M becomes a tightly integrated part of the 800xA DCS. PM856 Then offered and also described as a part of the ABB 800xA system offering.
ABB AC 800M PM856 CPU Modules
Several ABB AC800M PM856 CPU modules are available that vary in terms of processing power, memory size, and redundancy support. Each AC 800M CPU module is equipped with built in Ethernet port(s) for communication with other controllers and for interaction with operators, engineers, managers, and higher level applications. These ports can be configured for redundancy for those cases where availability is of paramount importance. It is also equipped with two RS-232C ports that can be used for point-to-point communication with programming/debugging tools and with third-party systems and devices.
AC 800 PM856 Com and I/O Modules
To each CPU PM856 module, a number of communication and I/O modules can be added,
for example:
- Additional RS-232C ports
- PROFIBUS DP, DP-V1 interface
- ABB INSUM interface
- MasterBus 300 interface
- S100 I/O interface
- S800L and S800 I/O modules
