FC 127 - Plant Loop Gateway Node Map (NPPG01-02, INPPR01)

The Plant Loop gateway node map function code performs two functions. First, it enables gateway time synchronization, and second, it defines each node type on the loop it resides in. This function resides in fixed block seven of the gateway module and differs between the local and remote gateway module.

 

Specifications S1 through S63 define the node types for respective Plant Loop addresses one through 63. This block must be defined in the local gateway to enable time synchronization. Each remote that has this block defined is synchronized to the local Plant Loop time.

 

Every node on the Plant Loop must be defined by this block. Failure to define every node correctly results in the loss of trend data. If multiple remote gateways reside on the same Plant Loop, only one must have this block defined. Failure to follow this rule results in the loss of trend data. If a Bailey 1090 system resides on the same Plant Loop as a remote gateway, the time synchronization function cannot be used.

NOTE: The range (node definition) can be set to 0, 1, 8, 10, or 16.

0 = vacant

1 = 1,400-tag operator interface unit

8 = process control unit

10 = INPCI01 Plant Loop to Computer Interface

16 = NCIU02/INPCI02 Plant Loop to Computer Interface, Management Command System, NPPG01 Plant Loop to Plant Loop Remote Interface and 5,000 Tag Operator Interface Unit
