Siemens TM1703ACP SICAM Automation Unit
A modular SICAM 1703-family automation and telecontrol platform for substation, energy and process applications.
Overview
TM1703ACP is the submitted identifier for the Siemens SICAM TM 1703 ACP automation unit. The platform is built from processing, communication and peripheral modules so the installed rack configuration—not the family name alone—defines the supplied system.
TM 1703 ACP supports telecontrol and substation-automation duties and has manufacturer evidence for IEC 61850 conformance in specified hardware/software combinations. The platform is discontinued, so project backups and installed module details are essential.

Features
- Combines telecontrol communication and local automation in a modular station platform.
- Allows project-specific communication and peripheral-I/O configurations.
- Supports IEC 61850 functions in documented hardware/software combinations.
- Provides an installed-base path for maintaining legacy SICAM station equipment.
Applications
- Electrical substation automation and bay/station communication.
- Energy and utility telecontrol installations.
- Process automation stations requiring modular remote I/O and protocols.
Lifecycle
- Archive the complete engineering project and communication configuration before intervention.
- Photograph the full rack, every module order number, firmware label and terminal block.
- Document time synchronization, station addresses, protocol mappings and redundancy behavior.
- Treat modernization as a system project because protocol and I/O behavior must be retested end to end.
FAQ
Why is a family-name match insufficient when ordering TM1703ACP?
The CPU, communication processors, peripheral modules, firmware and project configuration determine the actual automation unit, so a rack inventory is required.
What backup should be secured before servicing TM1703ACP?
Preserve the complete engineering project, parameter files, protocol mappings, station addresses, time-sync settings, firmware versions and I/O documentation.
How should IEC 61850 compatibility be checked for TM1703ACP?
Match the exact CP/CPC and peripheral hardware, firmware and conformance-document revision; family-level IEC 61850 support does not approve every build.
What makes a migration from TM1703ACP a system-level task?
Modern hardware can change protocol timing, data-point addressing, SOE behavior, GOOSE mapping and terminal allocation, all of which require staged station testing.
Which photographs make a TM1703ACP spare enquiry actionable?
Provide the rack overview, front and side labels of every module, backplane/terminal details, power module and any communication adapters.
