7 PARAMETER SETTING
(c) Default router IP address
Set the IP address of the router (default router) to be used when the
QJ71MT91 communicates with the target device on another Ethernet via
other than the router specified in the router information (refer to (e) below).
Set the value that satisfies the following conditions.
Condition 1: The IP address class is any of A, B and C.
Condition 2: The subnet address of the default router is the same as that
of the local station QJ71MT91.
Condition 3: The host address bits are not all "0" or all "1".
POINT
The default router is used for communication if the corresponding subnet address
does not exist in the router information (refer to (e) below) at data transmission.
(d) Number of routers set
1) Set the number of routers (within the allowable range) according to (e)
Subnet address and (f) Router IP address below when the QJ71MT91
communicates with the target device on another Ethernet via other than
the default router.
2) Set the necessary number of subnet addresses and router IP
addresses to the areas of (e) and (f) below.
(e) Router information: Subnet address
1) Set the network address (*1) or subnet address (*2) of the target device
when the QJ71MT91 communicates with the target device on another
Ethernet via other than the default router.
Set the value that satisfies the following conditions.
Condition 1: The IP address class is any of A, B and C.
Condition 2: All the host address bits are "0".
2) Set the router information in order, starting from the first target device.
*1 Set the network address of the target device when the class (network
address) of the local station QJ71MT91 differs from that of the target
device.
*2 Set the subnet address of the target device when the class (network
address) of the local station QJ71MT91 is the same as that of the target
device.
