Component Connections

The IRMIS schema, how components are interconnected:

• physically (housing hierarchy)

• logically (control hierarchy)

• power grid (power hierarchy)

• Each relationship type is hierarchical in nature (each child has a unique parent in each hierarchy). The hierarchies are modeled as node/edge graphs (DAGs).

Component Interfaces

• Each component type has the following properties:

• a set of ‘required’ interfaces

• a set of ’provided’ interfaces

• An ‘interface’ (both required and provided) restricts <<business rule>> the types of parent/child relationships that can take place (in any hierarchy)

• Thus an AllenBradley module (requires interface ‘AB_Slot’) cannot be inserted into a VME Chassis, which only provides an interface ‘VME_Slot’

IRMIS Future Developments

• Relating Process Variables to Components -- Data Mining

• Query PVs for records with field_type ‘INP’ or ‘OUT’

• Look for a characteristic signature in the INP string. Eg AB #Lx Ay Cz Sv

• This implies the existance of an Allen Bradley module (use DTYP for the specific module type). From IRMIS, we know which IOC has this component.

• By querying the ‘control interface required’ for the component, we have a limited number of component types that the component can connect to - (often only one). In the case of the A/B - we are left with the choice of an 8-slot or 12-slot chassis. Requires user input (once).

• Querying the required control interface of the chassis results in a choice of a PLC-5 or a remote adapter. The adapter number of this new component is obtained from the INP string.

• In this manner, one recursively applies the interface required/provided rule to extract the ‘infrastructure’ components that are implied by the existance of a given process variable.

IRMIS Future: Object vs Relational Modeling

• The data mining experience - object or relational modeling?

vcct1.3 - file based - single hierarchy - initial datamining

vcct20 - java based - 3 hierarchy - ‘schema 1’

irmis2 - idt - XAL - Hibernate ORM - object modeling - ‘schema 2’

PHP - web based viewer

irmis3 - AJAX - relational model - web based - ‘assembly schema3’

IRMIS Future Dev: Signal Tracing

• A component has in general a number of input signals, and a number of output signals.

• Each output signal is some function of the input signals, (and of the component itself).

• Extending the definition of a component output pin:

• Each component output pin has a ‘transfer function’ associated with it.

• The transfer function is similar to a line in a calc record:

• Example: A summing component. O=(A+B)/2. Output pin O is the sum of input pins A and B.

• Example: Fanout. Oj = I0 Output in Pin J = Input on Pin 0;

• (the transfer functions are indicated in green)

• With the pin transfer functions in place, one can now do end-to-end signal tracing (at least up-hill!).

• In the case of the APS timing system, it would thus be possible to trace the source of any event receiver module back to its ultimate source.

IRMIS Future Dev: Fault Tracing

• Trace failed PVs to locate the common part of the failed field bus path

• Can we have ‘state of health’ for general field bus communications? Or is there some signature (regex?) that can be defined to locates state of health PVs?

- Auto generate alarm handler config files with these PVs on IOC reboot

• Fault tracing is helped considerably if we can do general signal tracing.
