FC 200 - INFI-NET to Plant Loop Local Transfer Module Executive Block (INIPT01)

The INFI-NET to Plant Loop executive function code defines the parameters that control the operation of the INFI-NET to Plant Loop transfer module. Function code 200 resides in fixed block one.

 

The configuration lock S1 disables mode changes. This prevents modification of INFI-NET data point definition blocks (function code 201) once the module is placed in execute mode.  Specifications S2 through S4 (loop, node, module) define a location for redirection of Plant Loop messages sent to INFI-NET. Redirection allows a Plant Loop device to send tuning and configuration commands to an INFI-NET node. The module redirects tuning and configuration commands addressed to module number three or higher to the address specified in S2 through S4. The redirection address is tunable when the module is in the execute mode, and can be modified when the module is in the configure mode. Any tuning or configuration commands destined for the INFI-NET to Plant Loop transfer module should be exclusively addressed to module address two.

 

Trend data poll commands should be redirected by setting up an INFI-NET data point definition (function code 201) for every INFI-NET point trended across the module, rather than by tuning the specifications of the executive block.

 

The exception report poll rate for the INFI-NET and Plant Loop sides of the gateway can be set individually. The setting is in terms of milliseconds and determines the frequency that the database is scanned for points that have been updated and require transmission to the ultimate destinations.

 

Loop time synchronizing can be isolated between INFI-NET and Plant Loop or permitted to flow across the gateway. If time synchronizing is isolated, then trending is not permitted

to occur across the gateway.

200.1   Explanation

 

200.1.1  Specifications

 

S1

Specification S1 is the configuration lock. If set to zero, configuration changes are allowed. If set to one, configuration is locked. Once a configuration is  Locked, it cannot be unlocked.  The module must be initialized and reconfigured.

 

S2

Specification S2 identifies the loop number where tuning and configuration commands received on Plant Loop are to be directed. Tuning and configuration commands addressed to module number three or higher are redirected by S2.

 

S3

Specification S3 identifies the node number where tuning and configuration commands received on Plant Loop are to be directed. Tuning and configuration commands addressed to module number three or higher are redirected by S3.

 

S4

Specification S4 identifies the module number where tuning and configuration commands received on Plant Loop are to be directed. Tuning and configuration commands addressed to module number three or higher are redirected by S4.

 

S5

Specification S5 sets the exception report poll rate (in milliseconds) for the INFI-NET side of the gateway.

 

S6

Specification S6 sets the exception report poll rate (in milliseconds) for the Plant Loop side of the gateway.

 

S7

Specification S7 is the time synchronization specification. If set to zero, there is no time synchronization between the central loop and satellite loops. If set to  one, synchronization exists between the central and satellite loops.
