Transmission Speed; Parameter Setting Method - Mitsubishi Electric MELSEC iQ-R Series User Manual

Transmission Speed

Set the transmission speed of the master/local module.
Item Description
Transmission Set the transmission speed of the master/
Speed local module.
Precautions
• When "Transmission Speed" is set to "Auto-tracking", it takes approximately five seconds for the transmission speed to be
established with auto-tracking after the power-on. When a station returns after disconnection, it also takes approximately
five seconds for the transmission speed to be established with auto-tracking. 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.
• Set the same transmission speed in all the stations in the CC-Link system. Data link cannot be performed with a slave
station where the different transmission speed from the master station is set.
• The transmission speed that can be set varies depending on the overall distance of Ver.1.10-compatible CC-Link dedicated
cable. ( MELSEC iQ-R CC-Link System Master/Local Module User's Manual (Startup))
• Check whether the same transmission speed are set for both the master station and slave stations by obtaining (checking)
the transmission speed setting using the operation test of CC-Link diagnostics. ( Page 108 Checking the transmission
speed setting)

Parameter Setting Method

Select whether to set parameters of the master/local module with the engineering tool or with a program.
Item Description
■Parameter Editor
Setting Method
of Basic/ Select this item to set the parameter using the engineering tool. The
Application following are advantages.
Settings • Parameters can be easily set in the window without creating a
program for setting.
• The data will be automatically transferred between the devices of
the CPU module and the link special relay (SB), link special
register (SW), and link devices of the master/local module, or
between the module label of the CPU module and the link special
relay (SB) and link special register (SW) of the master/local
module.
■Program
Select this item to set the parameter using the dedicated instruction
(RLPASET instruction). The following are advantages.
• Parameters can be changed without resetting the CPU module.
• More master/local modules than the number of modules that can
be set using the engineering tool can be mounted.
*1 Set the mode and transmission speed using the engineering tool even if "Program" is selected.
