PRE-OPERATIONAL PROCEDURES AND SETTING

(d) Send frame specification (Bit 3)
Specify the frame format in which the QJ71MT91 will send data to the
target device.
[When corresponding bit is OFF]
Data are sent in the Ethernet (V2.0)-compliant frame.
[When corresponding bit is ON]
Data are sent in the IEEE 802.3-compliant frame.
(3) IP address setting (Switch 3, Switch 4)
Set the IP address of the QJ71MT91 on the local station.
b15
<Switch 3>
: 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 not "0" or "1".
If the conditions are not satisfied, a switch 3, 4 error (7303
In such a case, correct the switch setting and then switch the power OFF then ON or
reset the programmable controller CPU.
(a) When the QJ71MT91 is mounted on a redundant system
When the QJ71MT91 is mounted on the main base unit of a redundant
system, the IP addresses are assigned as follows.
System A, control system: IP address set
System B, standby system: The fourth octet of IP address set + 1
(Example) When 192.168.0.1 is set
System A, control system: 192.168.0.1
System B, standby system: 192.168.0.2
Also, the IP address assignment at a system switching differs depending on
the IP mode type set using the switch 5.
[For fixed IP mode]
Fixed IP addresses are assigned to system A and system B. Even if a
system switching occurs, the IP addresses are not switched.
[For redundant IP mode]
IP addresses are assigned to the control system and standby system. If a
system switching occurs, the IP addresses are also switched.
REMARK
When a value of 254 is set to the fourth octet of IP address of system A or control
system, the fourth octet of IP address of system B or standby system will be 253.
IP address : 192. 1.
