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 supported as an additional communication protocol, allowing LOGO! to act as a client or server. With the LOGO! CIM and LOGO! CMR communication modules, status information and alarms can be received via text message or email. Secure remote access via HTTPS or Open VPN allows configuration changes and diagnostics. GPS locating services can be used for tracking, signaling position data via text message or email. The LOGO! CMK2000 module enables LOGO! 8 to be used as an intelligent controller in the KNX system, supporting time and date synchronization.

Cloud Connectivity
