Siemens SIMATIC S7-1200 CPUs FW4.1 CPUs

The Siemens SIMATIC S7-1200 CPU series features upgraded firmware V4.1 that introduces performance improvements, extra features and support for forthcoming failsafe CPUs. The firmware has improved instruction processing for faster execution of PLC programs, while increased work memory makes extra resources available for program and user data.

Features include enhanced motion capabilities such as position control and support for analog 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. A built-in station web server allows flexible access via IP address.

There is also dynamic copy protection; support for a 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 CPUs are recommended for new designs. Versatile configurations of analog and 24 V digital inputs and outputs are available. The firmware can also be downloaded for existing S7-1200 CPUs.
