Product Overview

PRODUCT INFORMATION
Logic module LOGO!
Simply ingenious for small automation tasks
Easy installation, minimal wiring, convenient programming: LOGO! 8, the small controller from Siemens, allows for the quick implementation of basic automation projects. You save space in the control cabinet and can easily implement functions, such as timer switch, timer relay, counter, and auxiliary relay with the LOGO! logic module
Highlights
Engineered with LOGO! Soft Comfort
In addition to the usual operation in single mode, LOGO! Soft Comfort engineering software offers easy operation in network mode. Automatic configuration of the communication with visual representation in the network view, calling of up to three programs side by side, and easy transfer of signals from one program to another with drag-and-drop are only some of the many convenient options. Programs from previous versions can be integrated without any problems.
Integrated web server
Users need no HTML expertise to use the LOGO! Web Editor (LWE) to create application-specific web pages with their own images and icons. Users can configure the webserver to control automation components via mobile devices. The web server is integrated into all basic devices for monitoring and control with LOGO! via WLAN and Internet. The web server is protected by a password and is suitable for all common browsers.
Versatile communication
The Ethernet port of the basic devices enables communication of the LOGO! modules with each other and with all SIMATIC S7 systems. Modbus TCP/IP is an additional communication protocol for LOGO! 8. LOGO! can be a client or server in this case. With the LOGO! CIM and LOGO! CMR communication modules, you can receive status information and alarms of the LOGO! station via text message or email with y our smartphone or tablet. Secure remote access via https or Open VPN using the wireless network allows configuration changes and diagnostics on the web server of the communication modules as well as on LOGO! 8. Locating services via GPS can be used, for example, for low-price container tracking. The position is signaled to the LOGO! basic module or to a control room via text message or email. With the LOGO! CMK2000 communications module, LOGO! 8 can be used as an intelligent controller in the KNX system. The time and date synchronization is possible as ma aster or slave in networked systems.
Cloud connectivity
The latest logic module series, LOGO! 8.4, is offered with preconfigured cloud connectivity and open MQTT communication. Users can activate and configure a cloud connection with LOGO!. Through live access, the cloud provides access to the collected data during ongoing operations. LOGO! 8.4 can also be used as cloud gateway f or existing systems. This means you can, for example, export data to the cloud for which the memory in the controller is limited. The dashboard for the cloud data is created with LOGO! Web Editor and can be hosted directly in the cloud. The web app created can be opened with a smartphone, tablet or PC. The encrypted connection from the cloud to LOGO! 8.4 via TLS protocol ensures secure transfer of data in both directions, that is, writing and reading.
