I have been assigned the responsibility of connecting an RFID scanner to a PLC. While I am aware of RTA's standard module for simplifying this integration process, I am curious if there are any alternative solutions available. Any suggestions would be greatly appreciated. Thank you!
Although I cannot endorse any specific brand, in the past I have encountered Euchner units connected to Siemens PLCs. It is worth noting that Euchner also offers models compatible with Allen Bradley (AB) systems. Additionally, Turck is another reputable brand to consider. An Idec representative mentioned that their units can also be connected, but their software is required to set up tags in advance, which may not be suitable for all applications. For badge reading solutions, Fortress and RF Ideas are recommended. While Fortress can be on the pricier side, RF Ideas may be worth considering if you are looking for dual-band or encrypted tags, although results may vary.
Turck's RFID readers are compatible with popular industrial protocols like Ethernet/IP and ModbusTCP, making integration seamless. Additionally, Turck offers models with a built-in Codesys PLC for added convenience.
Sure, besides RTA's standard module, you might consider using third-party middleware like KEPServerEX. It simplifies the integration process as it has various drivers to communicate with multiple devices. RFID4CONTROL is another option, which directly adds RFID data to your PLC. It's worth noting that the best procedure depends greatly on your PLC model and the specific application of the RFID scanner. Hope this helps!
You certainly have other options beyond RTA's standard module. Beckhoff's RFID solutions are one recommendation; they seamlessly incorporate into their own PLC solutions. Another option could be the Siemens Simatic RF series which is explicitly built to work with their S7 PLC series. Furthermore, numerous third-party communication protocol conversion devices facilitate different kinds of integration. Finally, depending on the level of customization and control you need, coding the communication protocol directly could always be an alternative. This last option requires a good understanding of both your PLC and the RFID hardware, but it gives you maximum flexibility.
