Replacement Considerations with Safety Applications Chapter 4
Produce/Consume Safety
Tags
GuardLogix 5580 and Compact GuardLogix 5380 controllers can produce
standard tags as unicast or multicast, but they can only produce safety tags as
unicast. The controllers can consume safety tags as either unicast or multicast.
When you configure a produced safety tag, you are only allowed to configure
unicast connection options. Logix Designer does not allow you to configure
multicast connection options.
When you configure a consumed tag, you must consider the capabilities of the
producer:
• If the producer in the I/O tree of this controller is a GuardLogix 5580 or
Compact GuardLogix 5380 controller, and you are consuming a safety
tag, you must configure the consumed tag to use unicast.
• If the producer in the I/O tree of this controller is a GuardLogix 5570 or
5560 controller, or a Compact GuardLogix 5370 controller, the safety
consumed tag can be configured as either unicast or multicast.
• Produce/Consume from GuardLogix 5570 (V28) to GuardLogix 5570
(V28) in local chassis; and change the Producer to GuardLogix 5580
(SIL2 or SIL3)
• The GuardLogix 5580 can only produce safety tags using Unicast
connections. An older safety controller (such as GuardLogix 5570) in
the same chassis as the GuardLogix 5580 will not be able to consume
safety tags, because backplane consumed tags cannot be configured as
Unicast.
• For multi-controller Produce/Consume safety systems in the same
chassis, you must upgrade all the safety controllers to Studio 5000 Logix
Designer® version 31 or later. This works because V31 allows the
backplane safety consumed tags to be configured as Unicast.
The fault code for these unicast/multicast issues is
Code 0124 / Connection Request error / Invalid input network
connection type.
