5.7 Memory commands
When you want to test the memory of an MVB module, you can use memory
commands to read and alter memory contents. In addition to testing the MVB module
itself, you can also use memory commands to verify the VME back plane bus.
However, for testing the backplane, you need to have a Gateway CPU available.
The memory commands can also help you trace application level failures as you can
inspect inbound and outbound MVB Process Data Port contents with them.
These commands are mainly intended for troubleshooting in laboratory conditions, not
on board the train with an active system running.
The memory commands include
ADDR
MEM
RM
RP
SM (D)
SP (D)
The following sections describe these commands in alphabetical order.
