Page 81: Redundant System Function
Redundant System Function The redundant system function improves system reliability by making the RJ71GF11-T2 or the remote head module redundant so that the new control system can continue data link even if an error occurs in the control system. The following modules are required to use the redundant system function in the Process CPU. •...
Page 82 Redundant master station For the redundant master station, the master station (1) and the submaster station (2) are connected with a tracking cable. When an error occurs in the control system master station, the control is switched to the standby system submaster station to control the slave stations and continue data link.
Page 83 Redundant line In redundant line configuration, two network lines are prepared and a slave station is connected to each network line. (The RJ71GF11-T2 of both systems operate as a master station of each network.) When an error occurs in the control system network (1), the control is switched to the standby system network (2) to control the redundant system and continue data link.
Page 84: System Switching Operation
System switching operation In a redundant system, if the control system fails, the control system and the standby system are switched. In CC-Link IE Field Network, send data is transferred to the new control system after system switching to continue data link. This section describes system switching operations for each system.
Page 85 ■Cyclic transmission send/receive processing The RJ71GF11-T2 maintains cyclic transmission by the transfer of send data to the new control system when system switching occurs. The send range of cyclic transmission of both systems is as follows: • The own station send ranges of the link devices (RY, RWw) of both systems become the same. •...
Page 86 ■Precautions • When using the module in a redundant master station configuration, check the submaster function precautions before use. ( Page 76 Precautions) • Manual switching cannot be performed using 'Forced master switching command' (SB0019) of the submaster function. • As shown below, if the redundant configuration splits into two systems due to such a problem as cable disconnection, a continuation error occurs in the standby system CPU module because a network configuration mismatch occurs between the master station (1) and the submaster station (2).
Page 87 ■Cyclic transmission send/receive processing The slave station maintains cyclic transmission by the transfer of send data to the new control system when system switching occurs. The send range of cyclic transmission of both systems is as follows: • The own station send ranges of the link devices (RY, RWw) of both systems become the same when pairing is set. •...
Page 88 Redundant line In redundant line configuration, two network lines are prepared and a slave station is connected to each network line. (The RJ71GF11-T2 of both systems operate as a master station of each network.) When an error occurs in the control system, system switching occurs in the redundant system. The network switched to the new control system through system switching continues the control.
Page 89 ■Cyclic transmission send/receive processing The master and slave stations maintain cyclic transmission by the transfer of send data to the new control system when system switching occurs. The send range of cyclic transmission of both systems is as follows: • The own station send ranges of the link devices (RY, RWw) of the master stations of both systems become the same. •...
Page 90 Precautions ■Tracking • Of all refresh target devices of link devices (RY, RWw), tracking needs to be set for the devices in the own station send range. • Tracking cannot be set for link direct devices. • Do not set tracking for the link special relay areas (SB0020 to SB01FF), which are turned on/off by the system, or the link special register areas (SW0020 to SW01FF), where data is stored by the system.
Page 91: System Switching Request To The Control System Cpu Module
System switching request to the control system CPU module When the RJ71GF11-T2 mounted on the control system detects a network error, it issues a system switching request to the control system CPU module. However, depending on the operating status of the standby system, system switching is not executed. For details on the operating status of the standby system and whether system switching is executable, refer to the following.
Page 92 When the master/local module is powered on or is reset, even if the communication error with the system switching monitoring target station continues for the system switching monitoring time or longer a system switching request is not issued to the control system CPU module until each slave station goes back to normal.
Page 93 System switching monitoring target station When a system switching monitoring target station is set, if the RJ71GF11-T2 mounted on the control system detects a communication error with the monitored slave station, a system switching request can be issued to the control system CPU module.
Page 94 ■Precautions • When it is desired to give priority to continuation of communication for multiple slave stations, set two slave stations connected most closely to the master station (1) and the submaster station (2) as system switching monitoring target stations (3). In this case, when an error is detected in communication with both system switching monitoring target stations, a system switching request is issued to the control system CPU module.
Page 95: Wiring Precautions
Wiring precautions For a configuration including a star topology • When disconnection occurs between the control system of the redundant system and the switching hub, communications can be continued by system switching. However, if disconnection occurs between the switching hub and the system switching monitoring target station, because communications with the system switching monitoring target station cannot be continued, a communication error occurs in the standby system and system switching does not occur.
Page 96: Functions Restricted In A Redundant System
Functions restricted in a redundant system The following table lists the functions restricted when the RJ71GF11-T2 is used in a redundant system. FUNCTIONS Restrictions Transient transmission • To perform the transient transmission specifying the control system or standby system, acquire the current target station address (address of the control system or standby system) by using the module FB (RedundantSystem_GetAddress) and access the acquired address.
