Communicating with the VM600 MPS

A VM600 MPS can be configured in several ways, depending on the hardware installed in the

system rack (ABE04x). Figure1-3 shows the various possibilities for communicating with the

system. In all cases, one of the VM600 MPSx software packages (MPS1 or MPS2) is required

to perform the configuration.

In general, VM600 MPS racks can be classified as operating either with or without a CPUM

modular CPU card installed:

• A VM600 rack without a CPUM card, also known as a stand-alone rack, is a MPS system

that is not connected to a network.

In a stand-alone rack, each MPC4 and AMC8 card must be configured in turn using an

RS-232 link to a computer running one of the VM600 MPSx software packages (MPS1

or MPS2). The panels of MPC4 and AMC8 cards have a 9-pin D-sub connector for

configuring the card when used in a stand-alone rack.

• A VM600 rack containing a CPUM card (and, optionally, its associated IOCN card), also

known as a networked rack, is a MPS system that is connected to a network.

In a networked rack, the CPUM card acts as a “rack controller” and allows an Ethernet

link to be established between the rack and a computer running one of the VM600 MPSx

software packages (MPS1 or MPS2).

In general, communication between the CPUM and the MPC4 and AMC8 cards takes

place via a VME bus on the VM600 rack backplane. A networked rack allows all of the

MPC4 and AMC8 cards in a rack to be configured in ‘one-shot’ using a direct Ethernet

(or RS-232) connection to a computer running one of the VM600 MPSx software

packages

The MPC4 machinery protection card is available in different versions, including a

standard version, a separate circuits version and a safety (SIL) version

(see4MPC4/ IOC4T card pair).

The safety version of the MPC4 card (MPC4SIL) does not have a VME bus

interface so it cannot communicate with a CPUM or any other cards in a VM600

rack. Accordingly, the MPC4SIL card can only be configured via the RS-232

connector on its panel.

Figure1-3 (a) shows the simplest VM600 MPS configuration. This is a stand-alone rack, that

is, one not containing a CPUM card. In this case, each MPC4 and AMC8 card in the rack must

be programmed individually from a computer using an RS-232 link. This is done via a 9-pin

D-sub connector on the panel of each of these cards.

Figure1-3 (b) shows a networked rack containing a CPUM card. An Ethernet link can be

established between the computer and the MPS via this card. The connection is made on the

panel of the CPUM, hence at the front of the rack. Communication between the CPUM and

the MPC4 and AMC8 cards takes place via a VME bus on the VM600 rack’s backplane

except for MPC4SIL cards as they do not have a VME bus interface and cannot communicate

with a CPUM or any other cards in a VM600 rack.

Figure1-3 (c) shows a rack containing a CPUM card and its associated IOCN input/output

card. An Ethernet link can be established between the computer and the MPS via the IOCN.

The connection is made on the IOCN panel, hence at the rear of the rack. Communication

between the IOCN/CPUM and the MPC4 and AMC8 cards takes place via a VME bus on

the VM600 rack’s backplane – except for MPC4SIL cards as they do not have a VME bus

interface and cannot communicate with a CPUM or any other cards in a VM600 rack.
