Why Engineers Specify This Model
- Highest I/O density in the S7-200 family – 24 DI + 16 DO onboard eliminates the need for immediate expansion in most mid-size machines, reducing panel space and wiring cost.
- Dual RS-485 ports – Port 0 for HMI/SCADA communication and Port 1 for device-level networking run simultaneously without protocol conflicts.
- Freeport mode – enables custom ASCII/binary protocols for barcode scanners, weighing terminals, and third-party instruments without additional gateways.
- 6 high-speed counters @ 30 kHz – sufficient for multi-axis encoder feedback in conveyor and web-tension applications.
- Battery-backed RTC – supports time-stamped event logging and scheduled recipe execution without external clock modules.
- Proven field reliability – the S7-200 platform has a documented MTBF exceeding 100,000 hours in continuous industrial duty.

Application-Specific FAQ
Q: Can the CPU 226 DC/DC/DC control AC loads directly?
A: No. The transistor outputs are 24 V DC sourcing. For AC loads, use an intermediate relay or solid-state relay (SSR) module. Konmask can supply compatible relay output expansion modules.
Q: Is this CPU compatible with STEP 7 (TIA Portal)?
A: No. The S7-200 series uses STEP 7-Micro/WIN exclusively. TIA Portal supports S7-300/400/1200/1500 families. If you are migrating to TIA Portal, consider the S7-1200 CPU 1214C as a functional successor.
Q: How many expansion modules can be connected?
A: The CPU 226 supports up to 7 expansion modules on the local I/O bus, achieving a maximum of 248 DI / 248 DO / 35 AI / 12 AO.
Q: What is the maximum network size for a PPI multi-master network?
A: Up to 32 nodes on a single PPI segment at baud rates from 9.6 kbps to 187.5 kbps. Repeaters can extend the network to 126 nodes.
Q: Does the unit include a memory card slot?
A: Yes. The CPU 226 accepts a SIEMENS EEPROM memory cartridge (6ES7291-8GF23-0XA0) for program backup and recipe storage without a PC connection.
Q: What warranty applies to this purchase?
A: Konmask provides a 12-month warranty against manufacturing defects from the date of shipment. Warranty claims are processed within 5 business days of receipt of the returned unit.
