Siemens 6FM1470-3CA25 Video Display Module

The Siemens 6FM1470-3CA25 PLC video display module provides graphical monitoring for SIMATIC S5 systems. This module generates high-resolution graphics and text on an external monitor. It mounts directly into any S5-135U or S5-155U rack slot. You can use this module as a direct replacement for older video units.

Detailed Technical Specifications

The Siemens 6FM1470-3CA25 PLC video display module measures 250 mm in length. Its width reaches 160 mm across the main body. The total height goes up to 48 mm with all components installed. This unit weighs approximately 0.68 kilograms for secure mounting.

Key hardware parameters include:

Complete Model: Siemens 6FM1470-3CA25
Component count: 132 individual electronic parts
Connector ports: Two 20-pin screw terminal blocks
Video output: VGA (15-pin SUB-D female)
Energy storage: Eight aluminum capacitors (100 µF each)
Mounting system: Two rear locking levers
PCB layers: Six-layer high-speed construction
Display resolution: 640 x 480 pixels (VGA)
Color depth: 16 colors from a palette of 4096
Display memory: 256 KB dedicated video RAM

Application and Installation

The Siemens 6FM1470-3CA25 PLC video display module slots into any S5 rack alongside the CPU. It requires an external VGA monitor for visual output. This module displays process diagrams, trend graphs, and machine status screens. Consequently, you create high-quality operator interfaces without an external HMI.

Programming and Graphics Creation

This module uses simple graphic commands from the STEP 5 program. The Siemens 6FM1470-3CA25 stores all screen layouts in onboard flash memory. You program graphic objects using standard function blocks from the library. Therefore, creating dynamic process displays requires minimal additional coding effort.

Always power down the rack before inserting or removing this module. Connect the VGA cable securely to the 15-pin port. The module features LED indicators for power, communication, and video sync status. Furthermore, its conformal coating protects against dust and light moisture.
