1-1 Features
The V600 RFID System adopts electromagnetic coupling enabling contactless
data communications. It can significantly enhance factory automation (FA) sys-
tems incorporating large-scale decentralized control systems and small lot pro-
duction systems.
OMRON’s original Parallel Interface is built-in, enabling connection to general-
purpose Programmable Controllers using the I/O Units of Programmable Con-
trollers (PC). The V600-CA8A-Vhas PNP transistor output and the
V600-CA9A-Vhas NPN transistor output.
Easy to Use •Safety is ensured with powerful check functions such as an innovative error
logging function which records the 30 most current operational errors.
•An optional Monitor Unit can be mounted on the ID Controller for the offline
monitoring of system operations and reading of error log data and error mes-
sages, thus improving system start-up and on-site maintenance.
•Two Read/Write Heads can be connected to one ID Controller providing flexi-
bility for sophisticated production systems.

Read/Write Head (R/W Head) The R/W Head enables contactless communications with a Data Carrier (DC)
mounted on a stationary or moving pallet or other means of conveyance. The
epoxy resin mold makes it highly durable, maintenance free, and ensures stable
operation.
Data Carrier (DC) The Data Carrier can record data such as production indicators, and data can be
read or written at any time using the Read/Write Head. The DC is molded with
epoxy resin to withstand severe operating conditions and is sufficiently compact
to be attached anywhere.
Monitor Unit This convenient monitoring tool enables the user to communicate with DCs with-
out connecting to a host computer, as well as allowing readout of error condi-
tions. Refer to Section 4 Monitor Unit Operation.

1, 2, 3... 1. When a command is sent from the host computer to the ID Controller, R/W
Head 1 enters the waiting condition and waits for the arrival of the DC. The
command data at this time specifies the memory area from which data is to
be read by R/W Head 1.
2. When the DC arrives within communications range of R/W Head 1, the data
(format and machining/inspection command data) in the memory area indi-
cated by the read command is sent to the host computer as the response.
3. Based on the response data, the host computer transmits the workpiece
machining/inspection command to the PC.
4. Once operations in the machining/inspection process have been com-
pleted, a write command is sent to the ID Controller, and this time R/W Head
2 waits for arrival of the DC. This command sets the memory area to which
R/W Head 2 is to write data and set the machining/inspection results data.
5. When the DC arrives in the R/W Head 2 communications range, the machin-
ing/inspection results data is written to the memory area specified by the
DC.

3-1-1 Communications Control Procedure
OMRON’s unique host communications control procedure enables the ID Con-
troller to communicate with a general-purpose PC via the PC’s I/O Unit.
•The ID Controller has access to the PC via a total of 32 points (i.e., 21 input and
11 output points of the ID Controller are used).
•Eight points are used to write an address. The address space for the host uses
256 bytes (00 to FF). The leftmost two digits are used for page number settings
with DIP switches 1.

Set by the PC according

•Eight points are used for the data line. The ID Controller has access to the PC
via one byte.

Explanation 1, 2, 3... 1. The PC sends a command to the ID Controller.
2. The ID Controller interprets the PC command and executes local commu-
nications, and writes data to or reads data from the DC memory.
3. If it is a read command, the data read out is sent to the PC as the response. It
is a write command, a response (00) is sent to the PC.

3-1-2 Read and Write Functions
Command Processing The read/write functions are used for communications when the DC is station-
ary. Thus, before using these commands, it is necessary to check that the DC is
at a specific position. If the DC is not in a specified position, an error response is
returned.

1, 2, 3... 1. Once it is confirmed that the DC has stopped in the specified position, the
PC sends the command.
2. The ID Controller follows the command and performs either writing or read-
ing operations.
3. After completing processing, the ID Controller returns a processing com-
pleted response to the IBM PC/AT or compatible. The IBM PC/AT or com-
patible accepts the response, and once again starts the line workpiece (with
the DC attached) in motion.

3-1-3 Automatic Read/Write Function
Command Processing Under the automatic commands, the ID Controller does not return a response
until the DC comes close to the specified R/W Head. This means that the com-
munications path to the PC remains in the busy condition until the response is
returned, and the IBM PC/AT or compatible cannot send commands specifying
the other R/W Head of the same ID Controller.

1, 2, 3... 1. The PC sends the auto command to Head 1.
2. The ID Controller does not return the response until the DC comes close to
the specified R/W Head, and consequently, the IBM PC/AT or compatible
stays in the busy condition. If two R/W Heads are connected to the same ID
Controller, communications to Head 2 are not possible.
3. When the DC passes in front of a R/W Head, write or read processing is per-
formed.
4. Once processing is completed, the ID Controller sends a response to the PC
indicating that processing indicated by the auto command has been com-
pleted.
