Product Description
The Allen-Bradley 1747-M11 is a 32KB flash EEPROM memory module for SLC 500 systems, compatible with 5/03, 5/04, and 5/05 processors, and specifically usable with 1747-L532, 1747-L541, 1747-L542, and 1747-L543 SLC processors, but incompatible with 1746-BAS and 1746-BAST modules; Series A modules work only with SLC 5/03 Series A/B processors, while Series B modules work with SLC 5/03 OS302, SLC 5/04 OS401, and SLC 5/05 processors, requiring a 1747-M15 adapter for PROM programming, and offering 8KB memory with 64,000 words for storing up to 1000 instructions.
Is Your Device Showing These Signs?
The Allen Bradley 1747-M11 SLC 5/01 processor commonly experiences issues such as corrupted memory modules requiring replacement, backplane communication failures due to faulty capacitors, and power supply degradation causing intermittent operational faults. Program loss occurs from battery depletion; replace the battery to retain ladder logic. Resolve communication problems by verifying proper DH-485 network configuration and cable integrity. Address processor faults by inspecting I/O modules for short circuits and ensuring proper grounding to mitigate electrical noise interference.
Technical specifications
The Allen-Bradley 1747-M11 is a 32KB flash EEPROM memory module designed for SLC 500 systems, specifically compatible with certain 5/03, 5/04, and 5/05 processors (1747-L532, 1747-L541, 1747-L542, and 1747-L543). It's incompatible with 1746-BAS and 1746-BAST modules. Series A modules are limited to SLC 5/03 Series A/B processors, while Series B modules support a wider range of processors (SLC 5/03 OS302, SLC 5/04 OS401, and SLC 5/05) and require a 1747-M15 adapter for PROM programming, offering 8KB memory capable of storing up to 1000 instructions.
Our Repair Process for the
1747-M11
Our repair process for the Allen Bradley 1747-M11 SLC 5/01 processor begins with a comprehensive diagnostic evaluation to pinpoint the root cause of the malfunction. Memory modules are replaced if corruption is detected. Backplane communication failures necessitate capacitor replacement. Power supply degradation requires immediate power supply unit replacement. Battery replacement is mandatory to prevent program loss. Communication problems are resolved through DH-485 network configuration verification and cable integrity checks. Processor faults are addressed by inspecting I/O modules for short circuits and ensuring proper grounding to eliminate electrical noise.
