Chapter 3 The GEnet System Manager–Station Configuration
System Parameters Screen
The System Parameters Screen selection is used to modify parameters which determine
how the Ethernet Interface allocates its available buffer memory. This screen is also used
to modify Station Manager parameters.
The System Parameters Screen is shown below:

Memor y Pool Allocation Parameters
The Memory Pool Allocation fields define the buffer pools used by the Ethernet Inter-
face. The Ethernet Interface RAM memory available after all the Ethernet Interface
executive software and configuration information has been loaded is broken into four
fixed size pools.
The MEMORY ALLOCATION parameter specifies the percentage of available memory
to be allocated to each pool. For example, a value of 10 in this field would assign 10 per-
cent of available memory to be allocated to this pool. The total of the MEMORY AL-
LOCATION for all buffer pools cannot exceed 100 percent. If the total is less than 100
percent, some of the available memory will not be used.
Buffers are used to hold messages which are sent or received on the network and to save
state information regarding the communications software. IN ALL CASES, there must
be buffers available and of sufficient size to contain the messages sent or received.
Note
You should not change Memory Pool Allocation parameters without first
consulting GE Fanuc Automation
The Buffer Size of the Buffer Pools must be specified in increasing order as follows:
