New SIMATIC S7-1200 CPUs With Upgraded Firmware Recommended For New Designs, Now Available From RS Components

V4.1 firmware makes popular PLC platform faster, more flexible, and failsafe-ready

The new firmware has improved instruction processing for faster unnamed (62)execution of PLC programs, while increased work memory makes extra resources available for program and user data.

New features include enhanced motion capabilities such as position control and support for analogue or PROFIdrive drives. A PID control block allows temperature control in active heating or cooling systems, as well as interval measurements using high-speed counters. In addition, a built-in station web server allows flexible access via IP address. There is also dynamic copy protection, support for shared I-Device allowing connection of multiple controllers and fast data exchange, and enhanced configuration handling that allows modules to be specified and left unconnected without triggering alarms.

The firmware also introduces support for the forthcoming failsafe S7-1200 CPUs and signal modules (SM) for implementing safety-related appliances.

The latest S7-1200 FW4.1 CPUs, available now at RS Components, are recommended for new designs. 13 part numbers offer versatile configurations of analogue and 24V digital inputs and outputs. Version 4.1 firmware is also available to download for existing S7-1200 CPUs.
