Common Parameters (Network Range Assignment Screen); Send Range For Each Station (Lb/Lw Settings) - Mitsubishi Electric Melsec QJ71LP21 Reference Manual

5 PARAMETER SETTINGS

5.3 Common Parameters (Network Range Assignment Screen)

5.3.1 Send range for each station (LB/LW settings)

5 - 14
The common parameters are used to set the cyclic transmission ranges of LB, LW, LX
and LY that can be sent by each station in a single network. The common parameter
settings are required only for the control station. The data of the common parameters
are sent to the normal stations when the network starts up.
Assign the send ranges of the link devices (LB/LW) for each station in 16-point units for
LB (start 0 to end
The following example shows send range for each station (LB/LW settings) when each
of 512 points is assigned to station numbers 1 to 8.

POINT
(1) In order to enable 32-bit data assurance, it is necessary to set the number of
points of send range for each station in such a way that LB is a multiple of 20
and LW is multiple of 2. Also, each station's head device number must be set
in a similar way so that LB is a multiple of 20
details of the 32-bit data assurance, refer to Section 6.2.1.)
(2) For the assignment of the same points only to LB and LW, use the identical
point assignment setting. For the identical point assignment to LBs and LWs,
including low-speed LB and low-speed LW, use equal assignment.
