3 Product Description
The M-CPU 01 processor module is the central component of the HIMatrix M45 controller.
The module is always the leftmost HIMatrix M45 module on the DIN rail.
The M-CPU 01 module is used to store the operating system and the user program. The module
executes all central functions, including communication with the PADT and other systems. The
module monitors the supply voltage and operating temperature.
The configuration is performed using SILworX, see Chapter 4.3.
The module is suitable for sequence of events recording (SOE), see Chapter 3.4.6. The module
supports multitasking and reload. For more details, refer to the system manual (HI 800 651 E).
iA licence is required to use the events recording, the multitasking and the reload features.
The module has been certified by the TÜV for safety-related applications up to SIL 3
(IEC 61508, IEC 61511, IEC 62061 and EN 50156) as well as PL e (EN ISO 13849-1).
Further safety standards, application standards and test standards are specified in the
certificates available on the HIMA website.
3.1 Safety Function
The CPU monitors the sequence and the proper, logical execution of the operating system and
user program or the user programs. The following functions are monitored with respect to time:
Hardware and software self-tests of the processor system
RUN cycle of the processor system (including the user program)
I/O tests and processing of I/O signals
3.1.1 Reaction in the Event of a Fault
If the self-tests detect errors, the processing of the user program and the process data is
stopped.
For further information on the fault reaction of the processor module, refer to Chapter 6.1.
Module's faults are signaled by the Err LED located on the front plate, see Chapter 3.4.3.
3.2 Scope of Delivery
The module must be installed on a suitable M-SO CPU 01 socket to be able to operate. The
socket is not included within the scope of delivery of the module.
The socket is described in Chapter 3.6.
3.2.1 IP Address and System ID (SRS)
A transparent label is delivered with the device to allow one to note the IP address and the
system ID (SRS,System.Rack.Slot) after a change.
The label must be affixed such that the ventilation slots in the housing are not obstructed.
Refer to the SILworX First Steps manual for more information on how to modify the IP address
and the system ID.
