2.6 System Configuration Precautions
2.6.1 Precautions when using Redundant CPUs
When using the high speed data logger module in a redundant system, be sure to
mount the module to the extension base unit for CPU/redundant power supply.
The high speed data logger module cannot be mounted to the main base unit in a
redundant system.
• When the high speed data logger module is mounted to the Redundant CPU, it
can only access the own station CPU.
It cannot access CPUs of other stations.
• The high speed data logger module cannot access Redundant CPUs of other
stations.
• When the high speed data logger module is mounted to the C Controller module,
it can only access the own station CPU.
It cannot access CPUs of other stations.
• When the control CPU of the access target network module is a C Controller
module, only the control CPU of the network module can be accessed.
• When the network module is mounted to the C Controller module, the network
module cannot be used as a relay station.
