Main communication units
Connection example
Connecting the SR-X Series and SR-2000/1000/750 Series to a network requires a dedicated cable.
RJ-45 connector
(Ethernet, EtherNet/IP®, PROFINET)
9-pin D-sub / Strand wire
(RS-232C)
Connecting the SR-700 or BL-1300/700/180 Series to a network requires a communication unit compatible with the specific series and network.

- PLC link connectivity of PLCs made by various other manufacturers is possible via RS-232C/Ethernet.
- Serial communication can be used via USB when connected to a PC.
Typical connection example
Connecting to a network makes it possible to collect and manage various information from code readers. This allows for the construction of information systems for checking marking quality, changeovers, production management, and more.
The following example includes a network-connected code reader.
Serial code management for small-lot, multiple-variety production
Automatic product type identification is possible by reading the serial code on the production instructions. The operation details for each product type are shared from the PLC to each device (touch panel, laser marker, robots, etc.). This helps prevent errors during small-lot, multiple-variety production on a single line. Connecting the PLC to the host PC makes it possible to centrally manage operation details and production results directly on the host PC.
