EIP-200S Ethernet/IP Adapter
2.3 Faults / diagnostics
Module hot swap
The EIP-200S Ethernet/IP Adapter supports electronic module hot swap, which allows you to
replace modules while the device is active on the network without removing power.
A configuration mismatch due to an improper module substitution is considered a fault. A
subsequent hot swap that results in a match between the original configuration and the new
module configuration clears the fault and the EIP-200S Ethernet/IP Adapter resumes normal
operation.
Note the following issues regarding hot swap:
● No more than one module can be swapped at a time.
● All modules have to be present at power up or reset.
● Outputs go to a default state when a module is unplugged. The default state is normally 0
unless specified differently in the module parameters.
Communication faults
If you are unable to communicate with the EIP-200S Ethernet/IP Adapter, ensure that you
have completed the following :
● Check that the appropriate link LED, P1 or P2, is green. If it is off, check the cabling to the
network switch. The link LED must be on before proceeding to the next step.
● If the Network Status LED is off, the IP address is not set. If the Adapter is using DHCP
(factory default), check that the DHCP server is set up correctly and running. The
Network Status LED must be flashing green before proceeding to the next step.
● Perform a List Identity from the ZNX-EIP-200S Configuration Tool.
● Ensure that the IP address is unique on the network.
● Ensure that the IP address of the communication partner (controller or Configuration
Tool) is on the same IP subnet.
