4-1 Communication Designation Function
4-3
4-1-3 Designation of External Trigger System Communication (SI/RI/PI)
In the external trigger system communication designation, the communication is started at a leading edge of an external input signal.
The communication is directly controlled by output of a sensor which detects a tag in the communication area. So, the communication
can be executed even in a fast line without fail.
SI designation:
In the single designation (SI), the controller command processing is ended by terminating the communication.
RI designation:
In the repeat designation (RI), the system waits for a leading edge of the next input signal even after the communication is ended. The
communication is executed to the tag whenever the leading edge of input signal is detected. Repeat processing is ended by a command
process abort command (AA).
To the external input of ID controller
The system waits for a leading edge of an
input signal when a command has been
issued by a host. (An sensor is one of
examples.) The communication is exe-
cuted to the tag in the communication
area at the leading edge of the input sig-
nal. If the tag is not in the communication
area, an error occurs to indicate that there
is no tag in the communication area.
