Overview Manuals Access Control DH-485 Path Processor Service Product Applications

Features:

  • Plant-floor access to SLC 500 data files
  • Hardware-controlled Monitor and Modify permissions
  • Point-to-point or DH-485 network attachment
1747-DTAM-E combines local SLC data access with selected processor-service authority rather than acting only as a message display.

Its three fastest recognition cues are controlled data access, a DH-485 connection role, and maintenance functions that depend on processor state.

Access authority, network attachment, and processor-service actions remain separate controls, preventing the operator role from being mistaken for unrestricted programming access.
Apter Power can coordinate official-document review, quotation, and sourcing support for 1747-DTAM-E.
1747-DTAM-E SLC 500 Data Table Access Module Manuals, Datasheets, Links Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Mode selection: The module provides separate Monitor and Modify operating modes.
  • Hardware control: A factory jumper or user security switch enables or restricts data changes.
  • Fast navigation: Ten Quick Recall functions can point operators to approved frequently used addresses.
  • Direct link: The 1747-C10 cable provides the point-to-point connection to an SLC processor.
  • Network option: A 1747-AIC link coupler supports attachment as a DH-485 network device.
  • Startup behavior: Auto Attach initiates processor communication after the physical path is available.
  • Fault handling: Authorized operators can view and clear documented processor faults.
  • Mode control: Run or Halt changes depend on processor state and the SLC 5/03 REM keyswitch condition.
  • Memory transfer: CPU RAM and EEPROM content can be transferred through the module workflow.
  • Local SLC data work: Monitor or modify approved processor data-file addresses at the machine.
  • Processor maintenance: Review faults and perform authorized operating-mode changes.
  • Memory recovery: Transfer SLC CPU information between RAM and EEPROM during documented service procedures.
Description
At an SLC 500 machine, 1747-DTAM-E gives plant-floor personnel a dedicated route to processor data without requiring a general-purpose programming computer. It is a Data Table Access Module, so its value lies in controlled local service rather than in acting as a general HMI replacement.

A site can use 1747-DTAM-E to place recurring data and processor tasks within reach of authorized operators. The installed security arrangement and controller state determine how far that local access may proceed, keeping the operating role tied to the machine procedure.

When an SLC program or maintenance policy changes, 1747-DTAM-E should be reviewed as part of the complete service path. Address design, connection method, and recovery responsibilities need to remain aligned so a familiar keypad does not hide a changed processor boundary.

Technical notes
Data-type compatibility is the primary migration boundary for 1747-DTAM-E. Rockwell Automation states that the module does not support floating-point, string, or ASCII values available in later SLC 5/03 operating systems; stop the operator-interface design if any required address uses those types, and choose a supported access method instead.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why might 1747-DTAM-E reject an address after an SLC 5/03 program change?
Check whether the revised program moved the value into a floating-point, string, or ASCII data type. Those later types are outside the module boundary, so stop the screen change and use a supported address or access method.
If 1747-DTAM-E cannot Auto Attach to the SLC processor, what should maintenance check first?
Inspect the 1747-C10 direct connection or the complete 1747-AIC network path, then confirm link-coupler power and processor operation. Review node and setup values only after the physical link is sound.
Why can operators monitor values on 1747-DTAM-E but be unable to modify them?
Inspect the factory jumper or user security switch and compare its position with the approved procedure. Do not bypass the hardware control; obtain authorization before enabling Modify mode.
Why does 1747-DTAM-E show an SLC 5/03 but refuse a requested Run or Halt change?
Check the processor keyswitch. The SLC 5/03 must be in REM before the module can change operating mode; stop and obtain authorized physical access instead of trying to bypass the switch.
A red communication indicator appears on 1747-DTAM-E; how should the next check be chosen?
First note whether the indication is steady, flashing, or part of startup. Then follow the official status table to separate normal self-test, hardware or software failure, and illegal network setup before cycling power repeatedly.
What should be saved before 1747-DTAM-E is removed from a working machine?
Record Quick Recall addresses, security configuration, DH-485 node and topology, cable catalogs, processor keyswitch state, current indicator behavior, and the approved RAM/EEPROM recovery procedure. Attach the full nameplate to that service record.
