Chapter 1
Digital Module Operation in a Control System
By default, the Connection Reaction Time Limit is four times the RPI.
Use the default values for Timeout Multiplier (2) and Network Delay
Multiplier (200). The Network Delay Multiplier value is in terms of
percentage. Thus, 200 means 200%.
For more information on how to specify RPI rates, see the following:

• Compact 5000 I/O safety modules -

Connection Over an EtherNet/IP Network
When you configure a remote Compact 5000 I/O digital module, you must
configure the Connection over EtherNet/IP parameter in the configuration
for the remote adapter that connects the I/O modules to the network. The
configuration choice dictates how input data is transmitted over the network.
The Compact 5000 I/O digital modules use one of the following methods to
transmit data:
• Multicast - Data is sent to all network devices.
If you are using the I/O modules in a redundancy system, you must use
Multicast.
• Unicast - Data is sent to one or more controllers depending on module
configuration.
Unicast is the default setting.
IMPORTANT
To determine what is appropriate, analyze each safety channel. The default
Timeout Multiplier of 2 and Network Delay Multiplier of 200 creates a worst-
case input connection reaction time limit of 4 times the RPI, and an output
connection reaction time limit of 3 times the RPI.
Changes to these parameters must be approved only after a thorough review
by a safety administrator.
