Omron PLC Programming Cable
The OMRON CS1W-CIF31 is a USB-to-serial conversion cable for Omron PLCs. The full cable that connects a PC to an Omron PLC is typically the CS1W-CN226, which is a combination of the RS-232 converter and a cable to a specific PLC port. The user’s query for “CN226” likely refers to the CS1W-CN226 cable.
Technical Specifications and Features:
CS1W-CIF31:
