4.2 Power Up Sequence
The procedure for starting the remote I/O system [MEWNET-F] is as follows.
1. Power up all the remote I/O controlled slave stations.
↓
2. Power up the master station system (i.e. the system that the master unit is connected). (The remote
I/O control will be performed for the running slave stations at this point.)
↓
3. Set the CPU of the master station system to "RUN mode".
The basic procedure is as above, however, the procedure after the start-up may be different according to
the settings.
4.2.1 Remote I/O Mapping, Slave Station Connection Confirmation Mode
If a slave station registered in the remote I/O map has not been turned on, the operation will not start
until the slave station is turned on although the master station system has been turned on and set in
"RUN mode" (The PROG. LED of the CPU is blinking during confirmation). The remote I/O control will
be perfomred when setting to "RUN mode", if the master station system is turned on after all the
registered slave stations have been turned on.
Reference:
<7.3 Slave Station Connection Confirmation Mode>
4.2.2 Remote I/O Mapping, Slave Station Connection Not Confirmed Mode
Remote I/O control is performed only for the slave stations which have been already turned on when the
master station system turns on (3).
Even if there is a slave station which is not activated when the master unit is turned on, if it has been
registered in the remote I/O map, it will be controlled by the master unit after it powers up.
Reference: <6.2 Automatic I/O Number Allocation and Arbitrary I/O Number Allocation>
4.2.3 Remote I/O Map Not Registered Mode
Remote I/O control is performed only for the slave stations which have been already turned on when the
master station system turns on (2). (Automatic allocation)
If you turn on the slave stations after turning on the master unit, the CPU on the master station will not
be able to control the slave stations. You may not allocate I/O numbers in sequence.
Be sure to trun on the salve stations to be controlled first, then turn on the master station.
Turn on the master station system after turning on all the salve stations.
Reference:
<6.2 Automatic I/O Number Allocation and Arbitrary I/O Number Allocation>
When actually controlling devices, it is recommended to register an remote I/O map.
