Description

Different versions of the MPC4 card
The MPC4 card is available in different versions,
including “standard”, “separate circuits” and
“safety” (SIL) versions. In addition, some versions
are available with a conformal coating applied
to the circuitry of the card for additional
environmental protection against chemicals,
dust, moisture and temperature extremes.
Both the ‘standard’ version and the “safety” (SIL)
versions of the MPC4 card are certified to
IEC 61508 and ISO 13849, for use in functional
safety contexts, such as SIL 1 in accordance with
IEC 61508 and PL c in accordance with
ISO 13849-1.
The “standard” MPC4 card is the original version
and supports all features and processing modes.
The “standard” MPC4 is intended for safety
systems using a VM600 rack with a limited range
of cards, that is, “standard” MPC4/IOC4T card
pairs and RLC16 relay cards. It has a VMEcompatible slave interface so it is software
configurable via VME when there is a CPUx card
acting as a rack controller in the VM600 rack. It is
also software configurable via RS-232 (on the front
panel of the card).

DESCRIPTION (continued)
The “safety” (SIL) MPC4 card, known as the
MPC4SIL, was developed to permit a wider range
of installation options. Specifically, VM600 racks
that also contain condition monitoring cards such
as the XMx16 and relay cards such as the IRC4. To
safety certify these configurations, it was
necessary to ensure that the MPC4SIL is isolated
from the other cards in a VM600 rack, so that
there is no possibility of its configuration being
inadvertently modified.
Therefore, the MPC4SIL card does not include a
VME-compatible slave interface, does not
support the tachometer (speed) channels and
does not provide all of the signal processing
capabilities of the “standard” MPC4 card
(see Additional specifications – for “standard”
and “separate circuits” MPC4 cards only on
page 9).
Segregation of MPS and CMS
The VM600 rack, machinery protection cards,
condition monitoring cards and associated
software are designed for compliance with the
machinery protection system (MPS) and condition
monitoring system (CMS) segregation
requirements of the API 670 standard, which
ensures that the functionality of the MPS does not
depend on and is not compromised in any way
by the operation of the CMS
