Fault Exclusion Affecting Category Rating 

There is a combination of undetected faults that could cause a dangerous 
failure of the safety function in this application. The accumulation of the 
following two faults would disable your safety system from stopping the 
PowerFlex 70 drive: 

 

Short of P terminal to 24V 

 

Short of M terminal to 0V 

 

If a P terminal short to 24V and/or an M terminal short to 
0V are faults that must be detected as determined by your 

risk assessment, refer to 

Achieving a CAT 4 Safety Rating

for an alternative wiring scheme. 

 

Configure 

Set the Network IP Address for the 1791ES-IB8XOBV4 
Module

 

The module ships with the rotary switches set to 999 and DHCP enabled. 
To support the hardware configuration shown above, use the following 
configuration.  

Set the network address using one of the following methods: 

 

Adjust the three switches on the front of the module. 

 

Use a Dynamic Host Configuration Protocol (DHCP) server, such as 
Rockwell Automation BootP/DHCP Server Utility. 

 

Retrieve the IP address from nonvolatile memory. 

Using the Rotary Switches to Set the Network IP Address 

The module reads the switches first to determine if the switches are set to 
a valid number.   

Set the network address by adjusting the three switches on the front of 
the module. 

Valid settings range from 001…254. When the switches are set to a valid 
number, the module’s IP address is 192.168.1.xxx (xxx represents the 
number set on the switches). 

 

 

 

 

 

 

The module’s subnet mask is 255.255.255.0 and the gateway address is 
set to 0.0.0.0. When the module is reading the network address set on the 
switches, the module does not have a host name assigned to it nor does it 
use any Domain Name System. 

If the switches are set to an invalid number (such as 000 or a value 
greater than 254), the module checks to see if DHCP is enabled. If 
DHCP is enabled, the module asks for an address from a DHCP server.
