5GFK–0644A Chapter 1 Introduction
Reset Pushbutton
The Reset pushbutton provides a convenient means of reset if a failure occurs. If the
module is being used as a master, pushing the Reset button resets both the module and
operation of the link. The application program must be used to re–initialize the link. If
the module is being used as a slave and a fault has caused the module to stop operating,
pushing the Reset button resets the module while the rest of the link continues to
function.
Note
The Reset pushbutton should not be used if the link is operating
normally. Pressing Reset during normal operation causes the link to
stop operating. The diagnostic program logic interprets this as an
external link failure.
Serial Ports
The front of the module has two 20–pin, D connector, RS–422/485 serial ports. These
ports are used for connection to the I/O Link.
