Modular RFID: Gateway expands radio frequency identification on machine, in cabinet

Minneapolis, MN — The new Turck 2RFID module for the company’s BL ident RFID system adds to existing BL20 and BL67 network I/O systems. “BL ident’s modular design provides flexible integration into new or existing Turck systems,” says Mark DiSera, product marketing manager for the company’s network and interface division. “This modularity provides customization in both IP 20 rated cabinet installations and IP 67 rated field installations,” he says.

Minneapolis, MN — The new

Turck

2RFID module for the company’s BL ident RFID system adds to existing BL20 and BL67 network I/O systems. “BL ident’s modular design provides flexible integration into new or existing Turck systems,” says Mark DiSera, product marketing manager for the company’s network and interface division. “This modularity provides customization in both IP 20 rated cabinet installations and IP 67 rated field installations,” he says.

Up to 8 channels can be added to each BL ident node, depending on system requirements. All channels operate in parallel so there is no time delay during communication between the data carrier and module. “Ability to add multiple channels makes the system more affordable, because you only incur the cost of one gateway,” DiSera says. Additional standard I/O modules may reside in the same rack, still providing IP20 or IP67 protection. BL ident offers 2, 4, 6 or 8 channels and may be integrated into existing networks, including

Profibus-DP

and

DeviceNet

industrial networks and industrial Ethernet protocols:

Modbus-TCP

, Profinet, and

EtherNet/IP

.

Standard function modules and/or sample code are available for integration into the control and fieldbus environment. Additional functions, such as intentional switch-off of individual read/write heads, are inherent when the heads are installed in close proximity with overlapping air interface areas. Furthermore, a 32 kB memory allows asynchronous processing of the individual read/write commands, and LEDs display diagnostics for individual RFID channels and fieldbus-specific diagnostic messages.
