The new firmware now also equips Simatic S7-1200 compact controllers with a real-time tracing functionality for application diagnostics and debugging. The firmware version 4.0 now enables all Simatic S7-1200 CPUs to operate as Profinet iDevices in addition to the already available option of operating as a Profinet controller. The device is designed as a DC/DC/DC variant. In addition to line driver I/Os, its features include 24 volt DC standard inputs and outputs, Profinet functionality with two ports, and two analog inputs and outputs. Like its most powerful predecessor, the Simatic S7-1217C CPU has a processing speed of 0.08 microseconds per operation. Moreover, the compact CPU comes with line driver ports to drive stepping motor controls at a frequency of up to 1 megahertz. With 125 kilobyte (KB) capacity, the work memory of the Simatic S7-1217C CPU is 25 KB larger than the most powerful S7-1215C so far. Upgrades include the S7-1217C CPU and firmware version 4.0.
