CONFIGURED LIST BLOCK

3-50

this block. When the list data is demanded from this block, it will demand data from the other

block in the appropriate sequence. Configured list data is defined as foreground in the ICN

and MSC blocks (Foreground List attribute). All lists are made part of the Tagged Interface

File (TIF) or a comma delimited text Modcell Interface File (MIF).

When the configured list block is not being used to collect data (NO), no data is collected and

no database space is allocated to do so. This feature is used to identify variables that are not

part of ICN or MSC foreground data but are still needed for TIF or MIF generation. The TIF

file is used by PC-30 as a list of parameters available for device block building. The MIF file is

used by other device drivers as a list of parameters available for device block building. Any

attribute that is to be read or written from a computer display must be included in an interface

file.

3.6.2 Configured List Block Parameters

The mnemonics, valid values, and data types for all fields that may be selected for display

and/or be used in making softwiring connections are listed in Table 3-5. The following further

defines the configured list block configuration parameters.

Block Type

CL This is the configured list block type.

Input 1 through Input 99 .................................................................................................... C – –

For each input (1 to 99), connect any variable you wish to be placed in the list or leave input at

NONE.

LSP Connect any variable you wish to be placed in the list to one of the 99 inputs.

To include another list in this list, connect the "LISTOUT" connection

of the other list as an input to this list.

NONE No variable or list is defined for the input.
