Overview
The recommended RPI for EtherNet/IP implicit message connections are 1/2 of MAST cycle time. If the resulting RPI is less than 25 ms, the implicit message connections may be adversely affected when the diagnostic features of the CPU’s Ethernet I/O scanner service are accessed through explicit messages or the DTM.
In this situation, these timeout multiplier settings are recommended:
RPI (ms) |
Recommended Timeout Multiplier |
Connection Timeout (ms) |
|---|---|---|
2 |
64 |
128 |
5 |
32 |
160 |
10 |
16 |

NOTE: If you use values that are lower than those
recommended in the table, the network can consume unnecessary bandwidth,
which can affect the performance of the module within the system.
