AC 800M High Integrity Controller
The ABB AC 800M PM865 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 PM865 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 PM865 control builder AC 800M becomes a tightly integrated part of the 800xA DCS. PM865 Then offered and also described as a part of the ABB 800xA system offering.
ABB AC 800M PM865 CPU Modules
Several ABB AC800M PM865 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 PM865 Com and I/O Modules
To each CPU PM865 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
