Safety_Sts_LocalAddr An array of DINT that consolidates the Modbus statuses of the 440C-CR30 safety relay. This variable allows
other Allen-Bradley controllers to read the status through CIP messaging.
Each array data represents the output of this UDFB. This list corresponds to the UDFB output to each array.

DINT
Safety_Cmd_CommRset A manual-mode variable that resets the messaging instruction when triggered from the HMI terminal. BOOL
Safety_Cmd_CommRset_Auto An auto-mode variable that resets the messaging instruction when triggered from a user program. BOOL
Safety_EM_IO_Des A 22-array variable that represents the names of the 22 embedded terminals.
[0] represents embedded terminal 0, [1] represents embedded terminal 1, and so on.
