Reference Information
 Load factor of target
The load factor is calculated from the EDS information [Capacity] of each target. When EDS
information is not registered, "Impossible to calculate" is displayed.
Adapter communication load factor =
[Calculation 1-1] Calculation of the number of communication packets sent/received per
second (pps) *4
The calculation method is the same as [Calculation 1] of unit load factor.
*4 When "HUB Switch IGMP Snoop Function" is "Invalid" and "Connection Type"
is "Point to Point", multicast communication packets (pps) are added.
[Calculation 1-2] Calculation of multicast communication packets (pps)
The calculation method is the same as [Calculation 1] of unit load factor.
Packets that "Multicast communication" is set to "Yes" in the I/O map setting and
the connection type is "MultiCast" in the connection setting are to be calculated.
[Calculation 2] Calculating the cyclic communication allowable communication band (pps)
Calculate from the data size per packet *2 and EDS information [Capacity] for
target.
The calculation method is the same as [Calculation 2] of unit load factor.
[Calculation 3] Calculating the unit communication load factor from the number of
sent/received packets (pps) and sent/received data size
Calculate the unit communication load factor from the number of sent/received
packets (pps) and sent/received data size.
The calculation method is the same as [Calculation 3] of unit load factor.
