There are two operation modes, i.e., Command Execution mode and Self-Execution mode. Through the dip switch 3-2, you can specify
one mode of them to be started at the power ON. Also, you can change the mode by a mode change command (MO) from a host device.
(1) Command Execution mode
The communication is executed by an instruction (command) from a host device. In this mode, you can use all the command. All,
you can read/control the external I/O terminals (IN, OUT1 and OUT2) by a command from a host device.
(2) Self-Execution mode
The communication to a tag is executed automatically according to the operating conditions registered in the controller, the commu-
nication result can be judged (judgment conditions), and the self-completion operation, to which is output to the two external out-
puts (OUT1 and OUT2) or to the RS-232C port (result output), can be performed. The ID system does not need to be controlled
from a host device. So, a simplified system can be built up very quickly. The following operating conditions can be registered.
The preset operating conditions are stored in nonvolatile memory in the controller. So, you do not need to set them at every power on.
Item Description

tions One of the conditions below can be specified per output.
