(2) Transmission speed setting
For using the module as a local station or standby master station, the transmission speed can be set to "Auto-
tracking".
In that case, no transmission speed setting error will occur because the local station or standby master station
tracks the transmission speed of the master station automatically.
The transmission speed can be checked with the B RATE LED on the front of the module. (Refer to
22, CHAPTER 2.)
● When the transmission speed is set to "Auto-tracking", it takes about five seconds for the transmission speed to be
determined after powered on. This also applies when a station is reconnected to the network after disconnection.
When the terminal block is installed or removed or line status becomes unstable during the power-on, it may takes five
seconds or longer for the transmission speed to be established.
● The transmission speed that can be set varies depending on the total cable length.
For details, refer to
● Use the same transmission speed for all of the master station and device stations.
If the setting for even one of the stations is different, data link cannot function properly.
● To check whether the same transmission speed is set for all of the master station and device stations, obtain the
transmission speed settings in the loop test with GX Works2. (Refer to
(3) Mismatch in the number of points between parameter-set expanded cyclic
setting and installation status
If there is a mismatch in the number of points between the parameter-set expanded cyclic setting and installation
status, the L series master/local module stores an error code into SW0069. Also, it stores the matching status of
each station into SW009C to SW009F.
