1747-DTAM/D SLC 500 data access module

1747-DTAM/D provides SLC 500 data, mode and fault access at the operator service boundary.

System role and access path

Rebuilt from individual evidence

Unknown: verification boundary

A series-D listing identifies 1747-DTAM/D as an Allen-Bradley SLC 500 Data Table Access Module. Rockwell documentation describes access to SLC 500 data files, operating modes and fault functions.

This places the module at the operator and service access boundary of an SLC 500 control system, where commands and status are exchanged with the controller.

Unknown: exact firmware, cable, processor compatibility and condition for an individual 1747-DTAM/D unit.

System role

This section explains what the product does and where it acts in the surrounding system.

Function
Controls operator and service access to SLC 500 data files, modes and fault functions.
System position
Sits at the operator and service access boundary of an SLC 500 control system.
Upstream / inputs
SLC 500 data files and controller status feed the access module.
Downstream / outputs
Operator commands and service actions are applied to the SLC 500 access functions.
Limitations
Unknown: exact firmware, cable, processor compatibility and condition for an individual 1747-DTAM/D unit.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • A series-D listing identifies 1747-DTAM/D as an Allen-Bradley SLC 500 Data Table Access Module.

    Confidence: medium

  • Rockwell documentation describes the DTAM as providing access to SLC 500 data files, operating modes and fault functions.

    Confidence: high

Inferences

  • The DTAM sits at the operator and service access boundary of an SLC 500 control system.

    Confidence: medium

    Rationale: The exact-series listing supplies identity while Rockwell describes data-file, mode and fault access functions.

Unknowns

  • Unknown: exact firmware, cable, processor compatibility and condition for an individual 1747-DTAM/D unit.

    Confidence: low

    Missing evidence: The captured sources do not provide a unit inspection or a complete exact-suffix compatibility matrix.
