From an earlier controller model to a Compact GuardLogix 5380, CompactLogix 5380, CompactLogix 5480, GuardLogix 5580, or ControlLogix 5580 controller

When changing the controller type from an earlier controller model to a Compact GuardLogix 5380, CompactLogix 5380, CompactLogix 5480, ControlLogix 5580, or GuardLogix 5580 controller, verify that projects containing multicast produce tags are configured correctly.

Compact GuardLogix 5380 and GuardLogix 5580 controllers only produce safety tags as unicast. The controllers consume safety tags as either unicast or multicast. When configuring a consumed safety tag, consider the capabilities of the producer.

If the producer in the I/O configuration of this controller is a Compact GuardLogix 5380 or GuardLogix 5580 controller consuming a safety tag, configure the consumed tag to use unicast.
If the producer in the I/O configuration of this controller is a Compact GuardLogix 5370, GuardLogix 5570, or GuardLogix 5560 controller, configure the safety consumed tag as either unicast or multicast.

In releases before version 28.00, produced tags produce data at the requested packet interval (RPI) of the fastest requesting consumer. This RPI allows multiple consumers, with different RPI settings, to connect successfully to a producer. In releases version 28.00 and later, the first consumer of a produced tag determines the RPI of produced data. All subsequent consumers must request the same RPI value as the first consumer or they fail to connect and display error code 0112.

The device that sends the first consumer connection to the producing controller is the first consumer of a produced tag. The first consumer makes a request based on the order in which the producer and consumer control system powers up. Therefore, cycling power to the system can change the first consumer. A device cannot be configured to be the first consumer. It is difficult to identify which consumer sends the first request to the producing controller, so plan accordingly when configuring multicast produced tags.

To make sure consumers of produced tags connect to Compact GuardLogix 5380, CompactLogix 5380, CompactLogix 5480, ControlLogix 5580, and GuardLogix 5580 controllers:

For consumers running releases version 17.00 and earlier that are consumers of a produced tag from Compact GuardLogix 5380, CompactLogix 5380, CompactLogix 5480, ControlLogix 5580, and GuardLogix 5580 controllers:
Verify that all multicast consumed tags of a produced tag have the same RPI. If they do not, some consumers fail to connect.
For multicast consumers running releases version 18.00 and later:
Verify that all multicast consumed tags of a produce tag have the same RPI, or
Verify that all multicast consumers are configured to
Allow Consumed Tags To Use RPI Provided By Producer
