Clear Local Statistics MSTR Operation

The Clear Local Statistics operation (type 4 in the displayed register of the top
node) clears statistics relative to the local node where the MSTR has been
programmed.

Control Block
Utilization

The registers in the MSTR control block (the top node) contain the Clear Local
Statistics information as described in the following table:

3.2.7

Get Remote Statistics MSTR Operation

The Get Remote Statistics operation (type 7 in the displayed register of the top
node) obtains information relative to remote nodes on the network. This operation
may require multiple scans to complete and does not require a master data
transaction path. (See page page 40 for a listing of the TCP/IP Ethernet network
statistics).

The remote comm processor always returns its complete statistics table when a
request is made, even if the request is for less than the full table. The MSTR
instruction then copies only the amount of words you have requested to the
designated 4x registers.

Note: TCP/IP Ethernet routing must be accomplished via standard third-party
Ethernet IP router products.
