EKE-Electronics EKE-Trainnet MVB - RP - Read Logical Port Data

Troubleshooting with software
40
addr32= start address for displaying data
count8= number of consecutive memory locations you want to display
EXPLANATION
Use this command to read the contents of the MVB memory. This is useful when you
need to read the memory to verify the functionality of the VME back plane bus. Also,
manipulating the memory on the MVB module side can be a convenient way to debug
the high level application on Gateway CPU.
This command displays the content of bytes starting from memory address you specify
with the addr32 parameter. The count8 parameter specifies the number of bytes you
want to display starting from the address parameter.
Before this command, you need to set the addressing mode to logical or absolute with
the ADDR command. For more information, see the ADDR section on page 37.
The following table lists the significant physical addresses of the Shared Memory of the
module.
