Description
UCD240A101 3BHE022287R0101 redundant system requires some specific configuration options to successfully communicate. Use this department
The following redundant tasks can be performed:
·Configuration I/O
·Configure Producer Label
·Configuration Information (MSG) Command
·Configuring I/O for HMI configuration tags
For any output requiring undisturbed switching:
·Place these outputs in the highest priority task.
·Configure only the highest priority tasks.
Configure Producer Label
UCD240A101 3BHE022287R0101 To use the label in the redundant controller for a controller in another rack, use the communication mode
Is “None”. In the I/O configuration of the consumer controller, it is the remote CNB module (actual
CNB in redundant rack) Select “None” as the communication mode.
IMPORTANT For each module in the system, ensure that the request packet interval
(RPI) 375 milliseconds or less. If a longer RPI is used, then
The controller may be disconnected from the module during switching. This will
Causes the output to change state.
Important During switching, the connection of the label used by UCD240A101 3BHE022287R0101 in the redundant controller can
Can timeout.
·Data will not be updated.
·What acts on logic is the last data received.
After the switch, the connection will be re established and the update will start again

If the communication mode of the remote CNB module is set to non
“None”, module fault code will appear in RSLogix5000
16#000C。 This fault code indicates that the service request has
Service request error caused by invalid mode or state in the process.
