Questions fréquentes (FAQ)
-
What is the main difference between CP461-10 and CP461-11?
CP461-11 surfers upgraded RAM (256 MB vs. 128 MB) and larger flash storage, making it suitable for systems requiring more processing power and storage. -
Does CP461-11 support dual CPU redundancy?
Yes, it can be installed in redundant configurations to ensure high availability and failover protection. -
What is the maximum number sur I/O points this module can manage?
It can control up to 50,000 I/O points, especially when used with distributed and remote I/O unités. -
Which communication protocols are supported?
The module supports Vnet/IP, Ethernet, and FCS Bus, allowing seamless system communication and device integration. -
Is the CP461-11 hot-swappable?
While the module itself is not hot-swappable, in redundant setups, the standby module can be replaced without disrupting operation. -
What engineering tools are used for programming?
Yokogawa’s CENTUM VP Engineering Station (SENG) is typically used for configuration, control logic, and diagnostics. -
Can it be used in hazardous or corrosive environments?
Yes, the G3 environmental standard ensures operation in industrial environments with corrosive gases, assuming proper enclosure. -
Does it require a dedicated power supply?
No separate supply is required — it draws 24V DC from the system backplane sur the FCS rack. -
What maintenance is typically required?
Routine diagnostics, firmware updates, and visual inspections are sufficient; Yokogawa also provides predictive maintenance support. -
