Changing the slot number for a VM600 slimlinerack

To configure slot number coding for a VM600 slimline rack (ABE056), a DIP switch on the

rack’s backplane must be set in order to match the slot number used for the input/output card

by the configuration software (for example, VM600MPSx for a MPC4/IOC4T card pair).

As shown in Figure2-5 and Figure2-6(a), the DIP switch is accessible from the rear of the

VM600 slimline rack, when the cards are removed.

On most VM600 slimline racks, the DIP switch is installed with its “ON” text marking towards

the top. Although some have the DIP switch installed with its “ON” text marking towards the

bottom. This upside-down orientation is shown in Figure2-6.

Accordingly, it is important to note that the operation of the DIP switch depends on its

assembled/installed orientation. That is, the ON positions of the individual switches are

always towards the “ON” text marking, which can be on top (up) or bottom (down).

More specifically:

• For a DIP switch with “ON” on top: the switches ON positions are up (and OFF is down).

• For a DIP switch with “ON” on bottom: the switches ON positions are down (and OFF is

up). This upside-down orientation is shown in Figure2-6.

Irrespective of the orientation of the DIP switch, when looking into the rear of the rack with

the DIP switch located to the top left (see Figure2-6(a)), the least significant bit (LSB) is

always to the left and the most significant bit (MSB) is always to the right. It is also always the

case that the ON position (that is, with the raised part of an individual switch pushed towards

ON) corresponds to a logic0. while OFF corresponds to a logic1.

For a VM600MPSx/MPC4andIOC4Tsystem, the ABE056 rack DIP switch is typically set

to 03. as this is the slot number typically used by the VM600MPSx configuration software for

this type of rack. See2.1.2.1Slot number coding for cards in the rear of a VM600 slimline

rack.

For the VM600 slimline rack DIP switch, this translates as follows:

Slot 03 => 0011 in binary

=> (MSB) 0 0 1 1 (LSB) in significant bits

=> (LSB) 1 1 0 0 (MSB) as per switch orientation (reversed)

=> 1 1 0 0 in logic terms

=> OFF OFF ON ON in switch positions.

For a DIP switch with “ON” on top: this corresponds toDN DN UP UP.

For a DIP switch with “ON” on bottom: this corresponds to UP UP DN DN.

See Table2-1 for other examples of rack slot number to DIP switch translations for the

VM600 slimline rack (ABE056).

Figure2-5 shows a VM600 slimline rack DIP switch with “ON” on top configured for a

VM600MPSx/VM600 MPC4/IOC4T system in slot03.

Figure2-6(b) shows a VM600 slimline rack DIP switch with “ON” on bottom configured for a

VM600MPSx/VM600 MPC4/IOC4T system in slot03.MPC4 machinery protection card (ABE04x and ABE056)

The MPC4 card has the following panel elements (see Figure2-8):

1-One global DIAG/STATUS indicator for the MPC4/IOC4T card pair

This multi-coloured, multi-function LED is used to indicate:

• The status of the card configuration

• Whether special functions such as Trip Multiply (TM) or Danger Bypass (DB) are

inuse

• An MPC4 card failure due to a hardware or a software problem.

2-BNC connectors RAWOUT1 to RAWOUT4

A connector is present for each of the four measurement channels. Used to output raw

analog signals (corresponding to, for example, vibration or dynamic pressure).

3-BNC connectors TACHOOUT1 and TACHOOUT2

A connector is present for each of the two rotational speed channels. Used to output

speed/phase reference signals. These signals are TTL-conditioned.

4-Status indicators for the four measurement channels and the 2 rotational speed channels

Each multi-coloured, multi-function LED is used to indicate:

• Whether the signal input for that channel is valid

• The presence of an incoming signal in the Alert/Danger condition

• Whether the channel inhibit function is in use.

5-RS-232 connector

This 9-pin D-sub connector can be used to configure an MPC4 card in a stand-alone

rack. This is done via an interface cable from a computer running one of the VM600

MPSx software packages (MPS1 or MPS2). See Figure2-7 for details of the interface

cable
