"Sets the Output Stream States" (APP/LPA)

ITOS Mnemonic:  LPASETOUTPUT

View Options: (help)

Focus:	Maintenance / Operation
Structures:	Abstract / Concrete

Context:

Description:

Enables or disables event output streams. The output streams are SSR and GRB, corresponding to bit positions 0 and 1, respectively. The LPAEVHOUTMASK parameter will enable/disable the posting of events by an event handler to the LPA output posters. The LPAPOSTOUTMASK parameter will enable/disable writing of data to the physical output, SSR for events and SIU for GRB. A set bit in an output mask will ENABLE that output stage. A bit not set will DISABLE that output stage. The GRB_ID parameter sets the active GRB processor for evet posting.

Fields:

CPU_MSK (index)

Attribute(s):  

Brief:  "CPU Mask"

Instance(s):  cpus

Mask of logical IDs for target CPUs.

DB_ID (index)

Attribute(s):  

Brief:  "LPA_DB Instance ID"

Instance(s):  db

Specifies the numerical ID of an LPA configuration database instance. Each instance is generally associated with a distinct LPA category, such as norma or diagnostics.

OUTPUT_MASK (index)

Attribute(s):  

Brief:  "Output Disable Mask"

Instance(s):  evh_mask, lpa_mask

Mask of output streams.
