Function
The SIMATIC RF180C / RF182C and RFID 181EIP communica-
tion modules consist of a basic module and a connection block
that must be ordered separately.
The connection block is available in three versions:
•
M12, 7/8" (5-pole):
PROFINET/Ethernet is connected by means of an M12
connector, the power supply is connected by means of a
5-pole 7/8" connector. There are 2 connections each for
PROFINET/Ethernet as well as for the power supply. This
ensures that the SIMATIC RF180C/RF182C can be connected
to additional bus nodes without the need for external distrib-
utors. The removable connection block allows a base module
to be replaced without interrupting the supply voltage to other
bus stations.
•
Push-pull connector (according to IEC 61918):
PROFINET/Ethernet and the power supply are connected by
means of a push-pull connector. There are 2 connections each
for PROFINET/Ethernet as well as for the power supply. This
ensures that the SIMATIC RF180C/RF182C can be connected
to additional bus nodes without the need for external distrib-
utors. The supply voltage connectors can conduct currents of
up to 12 A (1L+ and 2L+). The removable connection block
allows a base module to be replaced without interrupting the
supply voltage to other bus stations.
•
M12, 7/8" (4-pole; not recommended for RF180C):
Ethernet is connected by means of an M12 connector, the
power supply is connected by means of a 4-pole 7/8"
connector. There are 2 connections for Ethernet and one
connection is available for the power supply. This connection
block can be used in applications where the 5-pole 7/8"
connector is already being used for other functions and
therefore cannot be used for the power supply.
A pre-assembled reader cable is used to connect one or two
readers to the communication module. The standard cable
length is 2 m. If other reader cable lengths are required, an
extension cable from 2 to 50 m in length can be used. The cable
can also be assembled by the customer as required.
The data in the transponder can be accessed as follows:
Direct addressing via absolute addresses.
Error messages and operating states (transponder in the field,
transmission, etc.) are indicated additionally by means of LEDs
and simplify commissioning and service.
SIMATIC RF180C/RF182C and RFID 181EIP have two reader
interfaces from which the readers are also supplied with voltage.
In the communication module , the power supply of the readers
has an electronic fuse. The maximum permissible current per
communication module for the readers is 1 A. It is of no impor-
tance here whether the current is drawn by 1 or 2 readers.
SIMATIC RF180C
The SIMATIC RF180C is designed for use in PROFINET net-
works. SIMATIC RF180C is integrated in SIMATIC STEP 7 via the
GSDML file. SIMATIC RF180C can then be configured via the
SW tool HW Config of SIMATIC Manager or another PROFINET
tool.
The application accesses the tag via FB45. FB45 accesses the
tag/Data Matrix Code via absolute addresses. For large volumes
of data and complex tag operations, the FB45 can process
chained commands.
Data is exchanged between SIMATIC RF180C and the applica-
tion by means of acyclic data records. This ensures that a large
quantity of data can be transferred from/to SIMATIC RF180C
without loading the bus cycle. This is advantageous when large
volumes of data are being transferred. SIMATIC RF180C can
also process chained tag commands in this mode extremely
quickly.
SIMATIC RF182C
The SIMATIC RF182C is designed for use in Ethernet networks
based on TCP/IP. The IP address of the SIMATIC RF182C is set
using the "Primary Setup Tool". The RF182C is then ready for
operation. This tool can be downloaded from
Communication with the SIMATIC RF182C is implemented using
XML commands. XML commands have a very simple structure.
This makes programming of the RF182C under any operating
system very easy. The simple command command set of the
RF182C can also be programmed easily in any Ethernet-capa-
ble controller.
RFID 181EIP
The communication module RFID 181EIP is for use in Ethernet/
IP networks. A DHCP server automatically assigns an IP address
to the RDID 181EIP. Alternatively, the user can assign issue static
IP addresses on the DHCP server. The standard tool for assign-
ing IP addresses is called the BOOTP/DHCP server and is
included in the RSLinx software package.
The RFID 181EIP communicates with the reader by means of
implicit and explicit messages. Commands and results are
transferred with explicit messages. The user sets up the com-
mands directly in the application program.
