Product Dimensions：The use of a safety tag with several multicast consuming controllers at varying firmware revisions can result in a connection timeout. If your application is configured with GuardLogix controllers consuming safety tags produced by a GuardLogix controller at revision 18.x, and the consuming controllers of one safety tag are at varying firmware revisions you may experience a connection timeout with error code 0x203. In the event of a connection timeout, all of the consuming controllers appear to connect to the tag and run for some time, but then the connection timeout occurs. If you use a single consumer of a safety tag, that consumer will connect and remain connected. To workaround this anomaly, set the revision of the producing controller to the same revision as the lowest revision of the consumers connecting to the safety tag. For example, if you have consuming GuardLogix controllers at revisions 17.x and 18.x, set the producing controller to revision 17.x to match the lowest revision of the consumers. Lgx00104877

Changes made to the Buffer Timeout value for FactoryTalk Alarm subscribers do not take effect until the existing buffer has been deleted. The FactoryTalk alarm buffer (stored in Logix controller memory) is designed to persist through power cycles. If you change the Buffer Timeout value (via the Communication Setup dialog in FactoryTalk View SE), the controller does not use the new timeout value until the existing buffer is deleted and then recreated. To force recreation of this buffer, you can either:

• Redownload the project to the controller

• Disconnect the FactoryTalk Alarm subscriber and leave it disconnected until the existing timeout expires. Lgx00069461
