Overview
SIMATIC RF640R is a powerful UHF reader with integral antenna
that is suitable for applications at single recording stations, in
conveyor systems or production plants. Due to its high maximum
transmission power of up to 2 W ERP (ETSI) / 4 W EIRP (FCC),
longer ranges can also be achieved. The high degree of
protection of the overall system is a guarantee for problem-free
use, even under the most difficult environmental conditions.
Instead of the integral antenna, an external antenna of the
RF600
series (SIMATIC RF620A, RF640A, RF642A, RF660A) can
be used. The reader offers 2 digital inputs (24 V) and 2 digital
outputs (typ. 24 V/0.5 A) that have protection circuits for
industrial use.
The integrated processing logic of the reader enables numerous
functions to be executed in the device itself. For example, the
reader offers extensive, intelligent filter functions, a parameteriz-
able state machine for forwarding the data, the automatic control
of the digital outputs for signaling functions, and the extensive
configuration of response message frames. The advantage:
Thanks to its intelligence, this considerably reduces the cost for
additional software modules (RFID middleware). The reader is
configured by means of the easy-to-use SIMATIC RF-MANAGER
Basic software, which is provided on a free CD supplied with
each reader.
Data communication takes place via an XML protocol with
TCP/IP; the reader provides an Ethernet interface for this pur-
pose. The protocol is compatible with the SIMATIC RF670R.
■
Application
The stationary SIMATIC RF640R UHF reader with its integral
antenna is suitable for applications in production (with PC/IT
interface), production-level logistics, distribution, supply chain
management, asset management, service processes or material
flow control.
The digital inputs and outputs (DI/DO) are used for simple
process interfacing (sensors, actuators).
The SIMATIC RF640R supports the established EPCglobal
Class 1, Gen 2 standard and is offered in three versions:
compliant with ETSI for Europe, compliant with FCC for USA/
Canada, and compliant with CMIIT for China.
