        Overview Manuals Display Hardware S5 Data Link Memory & Serial Power & Rack

        Features:

        • The WF 470C generates 256x512 color process graphics through BAS or TTL monitor outputs.
        • A 256-byte dual-port RAM moves requested process values and control records across the SIMATIC S5 backplane.
        • Three memory slots, internal RAM, a programming interface, and a second serial path organize display data and peripherals.
        The processor combines stored picture definitions with controller values before the video section refreshes the connected monitor.

        Shared dual-port RAM coordinates S5 requests and acknowledgments without placing display variables directly on a serial link.

        Rack power feeds the core electronics, while memory buffering and the external TTY supply serve separate retention and interface functions.

        The Siemens 6FM1470-3CA25 WF 470C Color Display Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        WF 470C Processing and Video Structure

        • Processor core: An Intel 80C186 processor executes the RMOS real-time display functions at 12 MHz.
        • Picture hardware: Dedicated picture memory and video processing generate the configured color screen.
        • Monitor paths: BAS and TTL outputs provide separate RGB video connection formats.
        • Graphics timing: The display system uses 256x512-pixel graphics with a 50 Hz repeat frequency.

        Dual-Port RAM Exchange with the Controller

        • Shared memory: A 256-byte dual-port RAM transfers coordinated records between the S5 and display module.
        • Data request: The WF 470C places the requested S5 data type and address in the coordination area.
        • Controller response: The S5 function block writes the requested value into the shared transfer area.
        • Picture selection: The controller can send the picture number and keyboard-related control bytes through the same link.

        Program Storage and External Data Paths

        • User slots: Three positions accept SIMATIC RAM or EPROM memory modules up to 128 KB each.
        • Internal RAM: The WF 470C adds 64 KB of internal user RAM beside the removable memory positions.
        • Programming path: A serial PG interface connects the programming device to the display module.
        • Second serial path: The additional interface connects the documented printer or supported external equipment.

        S5 Rack Supply and Buffering

        • Rack power: The SIMATIC S5 bus supplies 5 V DC to the module electronics.
        • TTY power: An external 24 V DC level supplies the active TTY interface where configured.
        • Buffering: The configured jumper arrangement selects S5-only or combined module buffering.
        • Module format: The WF 470C occupies the documented double-height Eurocard mechanical format.
        Description
        Siemens 6FM1470-3CA25 is a WF 470C color display module that generates configurable process pictures for SIMATIC S5-115U, S5-135U, and S5-155U systems. An 80C186 processor runs the real-time display software, and the color video section sends the generated image to BAS or TTL monitor outputs.

        Process data reaches 6FM1470-3CA25 through a 256-byte dual-port RAM shared with the SIMATIC S5 bus. The controller function block places requests and values in the coordination area, and the display module reads those records to update variables, messages, and picture selections.

        Three user-memory positions on 6FM1470-3CA25 accept RAM or EPROM modules with as much as 128 KB per slot, while a separate 64 KB internal RAM area supports the WF 470C. The serial PG connection serves programming access, and the second serial interface provides the documented printer or external-device path.

        The SIMATIC S5 bus supplies the 5 V electronics of 6FM1470-3CA25, with an external 24 V source used for the active TTY interface. Buffering arrangements preserve the clock and designated memory areas, while the double-height Eurocard format places the module and its monitor connectors in the S5 rack environment.
