Function Blocks
NOTE: Refer to the
Function Code Application Manual,
I-E93-900-20 for the specifications and outputs of the LMM function
codes.
The range of function blocks for the logic master module is 0
through 1,023. Blocks 0 through 23 are reserved for the execu-
tive block and outputs of all the fixed address system blocks.
The executive block handles overall module operation. The
fixed address system block outputs can be used anywhere in
the configuration. Blocks 24 through 1,023 are user-assign-
able. Table
lists the outputs of the executive block.
Function Codes
The control strategy is designed with operations from the INFI
90 Function Code Library residing in ROM. Each code has a
set of parameters with default values. Change these values to
meet the requirements of your application. Table
