Instructions
(1) Replace the existing MELSECNET/MINI(-S3) with MELSECNET/H (remote I/O network).
Install new network cables: optical cable (loop) or coaxial cable (bus).
(Optical cables are used for the following example.)
(2) When the I/O module of the existing MELSECNET/MINI(-S3) remote I/O station is of terminal block type,
utilize the existing terminal block with the external wiring through a Q Series large type base unit and the
following products.
•
Q Series large type I/O modules
•
Q Series I/O m upgrade tool manufactured by Mitsubishi Electric Engineering Co., Ltd.
(3) In MELSECNET/H (remote I/O network) network parameter, set the master station side devices to be the
same as the ones assigned to the existing MELSECNET/MINI in order to avoid program modification.
The following example shows the network parameter settings of MELSECNET/H (remote I/O network) after
replacement in the case where the transmission devices of the existing MELSECNET/MINI(-S3) network were
X/Y100 to 1FF.
(1) Existing MELSECNET/MINI(-S3)
Auto refresh parameter
(2) Network parameter setting example
(3) Module selection example
• MELSECNET/H (remote I/O network) can utilize Q Series large type base unit. Wiring time can be
reduced by utilizing the external wiring of MELSECNET/MINI remote I/O station, which consists of
existing building block type I/O modules.
•
Progr
am modification is not required because the number of occupied points are the same for
each I/O module to be replaced. Therefore, programming time and debugging time after the
replacement is reduced.
