Signal modules can be connected to the CPU to increase the capacity of digital or analog I/O.

PLC digital I/O module of the proven SIEMENS SIMATIC series – 6ES7223-1PH32-0XB0 for use with the SIMATIC S7-1200 series enables communication between the processor and input-output devices. It is an advanced device that helps the programmable logic controller to use its potential as efficiently as possible, and was designed specifically to work with SIMATIC S7-1200 PLCs.

Signal cards can also be added to the CPU itself to increase the number of digital or analog I/Os, and battery cards can be added to the controller to meet application requirements without increasing the size of the controller itself. CPU 1212C supports up to two, CPU 1214C, CPU 1215C and CPU 1217C up to eight additional signal modules. With its advanced expansion capabilities, the SIMATIC S7-1200 is ideally suited to any precision automation task.

Instant troubleshooting of encountered problems and localization of errors in real time thanks to the new unified display concept reduces total startup time and eliminates unwanted production downtime almost to zero. Built-in, system-integrated diagnostics without additional programming greatly accelerates and facilitates fault detection, gets rid of production delays while providing the grounding necessary for advanced safety functions.

The continuous development and enhancement of the versatility of the communication modules in the S7-1200, new applications such as predictive maintenance and machine learning, with their properties make the entry into digitalization a standard. Offering open communication protocols such as serial communication, PROFIBUS, IO-Link, AS-Interface, PROFINET, Industrial Ethernet, Telecontrol, as well as modern vertical and horizontal communication, MQTT and OPC UA, which require memory access and constant data analysis effectively enable the implementation of this process.
Simulation tools like engineering in the TIA portal give full access to the entire digital automation system, reducing the total time to market, diagnostic functions increase their efficiency and the connection to management provides increased flexibility and transparency.

Safety Integrated is the ability to connect PROFIsafe devices via PROFIBUS and PROFINET, and control data integrity across all program components. Mixed operation of fail-safe system modules and standard I/O modules is also supported. A system specially created to effectively protect any investment.

SIEMENS SIMATIC S7-1200 binary I/O SM 1223, 8DI / 8DO – 6ES7223-1PH32-0XB0 module’s compact, precision design with integrated I/O, communication interfaces that meet high industry standards, and a range of applied technology features make SIMATIC series modules a permanent, integral part of complex automation solutions.
