card pairs and the RLC16 relay card. It has a VME-compatible slave interface so that it

can be configured via software via VME when VME is available.

It is software configurable via VME when acting as a rack controller in a VM600 rack.

It is also software configurable via RS-232 (on the front panel of the card).

The ‘Secure’ (SIL) MPC4 card (MPC4SIL) has been developed to provide a wider range of installation options.

Specifically, the VM600 rack also contains condition monitoring cards (e.g. XMx16) and relay cards (e.g. IRC4).

In order to certify the security of these configurations, it is necessary to ensure that the MPC4SIL

is isolated from the other cards in the VM600 chassis so that its configuration is not inadvertently modified.
