The Network Delay Multiplier can be approximated by the following equation:
[Maximum Observed Network Delay + Margin_Factor]
÷
RPI
Understanding the
Configuration Signature
Each safety device has a unique configuration signature, which defines the
module configuration. The configuration signature is composed of an ID
number, date, and time, and is used to verify a module’s configuration.
Configuration via RSLogix 5000 Software
When the I/O module is configured by using RSLogix 5000 software, the
configuration signature is generated automatically. You can view and copy the
configuration signature via the Safety tab on the Module Properties dialog box.

EXAMPLE
Calculate the Network Delay Multiplier from Maximum
Observed Network Delay
If:
RPI = 50 ms
Maximum Observed Network Delay = 20 ms
Margin_Factor = 10
Then, the Network Delay Multiplier equals:
[20 + 10]
÷
50 = 60%
