Figures 6-1. 6-2 and 6-3 show block diagrams of the main different versions of the CPUM
card with their different CPU modules:
• Later versions of the CPUM card (PNR 200-595-076-HHh or later) fitted with
the PFM-541I or equivalent CPU module (see Figure6-1). This is an Ethernet redundant
version of the card.
• Later versions of the CPUM card (PNR 200-595-082-533 or later) fitted with
the PFM-541I or equivalent CPU module and the additional/redundant serial
communications module (see Figure6-2). This is a serial redundant version of the card.
• Earlier versions of the CPUM card (PNR 200-595-075-HHh or earlier) fitted with
the MSM586EN or equivalent CPU module (see Figure6-3). This is an Ethernet
redundant version of the card.
Similarly, Figure6-4 shows a block diagram of the IOCN card.
See 13Configuration of CPUM/IOCN cards for information on how to use the jumpers on
the CPUM and IOCN cards to modify the operation of the external communications
interfaces.
6.5 Serial port naming
For the CPUM card:
• The RS-232 serial port on the card’s panel, shown as RS-232 (COM0) in Figures 6-1.
6-2 and 6-3. corresponds to the RSFRONT device in the modbusDefault.cfg
configuration file.
(RSFRONT corresponds to the ser2 device driver of the QNX operating system used by
the CPUM card. This is the primary serial communications port.)
For the IOCN card:
• The serial port on the card’s panel, shown as RS (COM1) in Figure6-4. corresponds to
the RS device in the modbusDefault.cfg configuration file.
(RS corresponds to the ser3 device driver of the QNX operating system used by the
CPUM card. This is the secondary RS-serial communications port.)
• The serial ports on the card’s panel, shown as A (COM2) in Figure6-4. correspond to
the SERIAL_A device in the modbusDefault.cfg configuration file.
(SERIAL_A corresponds to the ser4 device driver of the QNX operating system used by
the CPUM card. This is the first of the additional serial communications ports and
requires that the optional additional/redundant serial communications module is fitted.)
• The serial ports on the card’s panel, shown as B (COM3) in Figure6-4. correspond to
the SERIAL_B device in the modbusDefault.cfg configuration file.
(SERIAL_B corresponds to the ser5 device driver of the QNX operating system used by
the CPUM card. This is the second of the additional serial communications ports and
requires that the optional additional/redundant serial communications module is fitted.)
Operation of LEDs on CPUM panel
6.6.1DIAG LED
The CPUM card’s DIAG LED is used for the following purposes:
• To indicate normal operation.
• To indicate the activation of special functions (related to CPUM security settings).
Further information is given in Table6-1.
Table6-1:Behaviour of DIAGLED
Behaviour of
DIAGLED Event(s)
Off (continuous) The CPUM is off or starting
Green (continuous)
The CPUM is operating normally and access to the CPUM card is
allowed (CPUM Access Lock: Unlocked).
That is, VM600 MPS rack (CPUM) security is not being used.
Green blinking slowly
(approximately once
per second)
The CPUM is operating normally but access to the CPUM card is
restricted (CPUM Access Lock: Locked).
That is, VM600 MPS rack (CPUM) security is being used.
Green blinking quickly
(approximately twice
per second) for five
seconds
The CPUM card is resetting to its default security settings.
That is, VM600 MPS rack (CPUM) security will not be used.
PROCESSING MODES AND APPLICATIONS
This chapter describes the processing modes that can be configured on the VM600 MPS (for
example, shaft relative vibration, broad-band pressure). Additional background information is
provided on the types of measurements that can be performed in these modes.
The MPS is generally fully configured in the factory before delivery and can be employed as
is. In some cases one of the VM600 MPSx software packages (MPS1 or MPS2) can be used
to allow further configuration of system parameters, or to reconfigure the MPS if it is extended
by the addition of MPC, IOC or relay cards (such as the RLC16).
NOTE: Refer to the relevant manual for further information: VM600 MPS1 software
manual or VM600 MPS2 software manual.
7.1 Different versions of the MPC4 card
The MPC4 machinery protection card is available in different versions, including a standard
version, a separate circuits version and a safety (SIL) version, as described in
4MPC4/ IOC4T card pair.
However, the safety MPC4 card (that is, the MPC4SIL) does not provide all of the signal
processing capabilities supported by the standard and the separate circuits versions of the
MPC4 (seeTable7-1)
