E Timing & Performance
E.1 General Information
This chapter specifies timing and performance parameters that are verified and documented for
the Anybus CompactCom 40 EtherNet/IP.
Category
Startup Delay
NW_INIT Handling
Event Based WrMsg Busy Time
Event Based Process Data Delay
For further information, please consult the Anybus CompactCom 40 Software Design Guide.
E.2 Internal Timing
E.2.1 Startup Delay
The following parameters are defined as the time measured from the point where /RESET is
released to the point where the specified event occurs.
Parameter
T1
T2
E.2.2 NW_INIT Handling
This test measures the time required by the Anybus CompactCom 40 EtherNet/IP module to
perform the necessary actions in the NW_INIT-state.
Parameter
No. of network specific commands
No. of ADIs (single UINT8) mapped to Process Data in each direction. (If the network specific
maximum is less than the value given here, the network specific value will be used.)
Event based application message response time
Ping-pong application response time
No. of simultaneously outstanding Anybus commands that the application can handle
Parameter
T100
E.2.3 Event Based WrMsg Busy Time
The Event based WrMsg busy time is defined as the time it takes for the module to return the H_
WRMSG area to the application after the application has posted a message.
Parameter
T103
