FAQS

• What is the difference between CC-PCNT01 and CC-PCNT02?
  The CC-PCNT02 is a C300 series controller in the Honeywell Experion PKS system. As the enhanced successor to the CC-PCNT01, it doubles the memory from 32 MB to 64 MB, upgrades the core chip to resolve component obsolescence, and supports advanced function blocks such as the Profit® Controller. It is fully backward compatible and can directly replace the -01 model without major system overhauls.
• What are the operating temperature and power requirements for the CC-PCNT02?
  The maximum operating temperature is typically 70°C, with a standard range of -20°C to +70°C. It requires a 24 VDC power supply.
• How are C300 controllers connected to the network?
  They connect to the upper system via Fault Tolerant Ethernet (FTE) (yellow cable to FTEA, green to FTEB), and to I/O racks via IOLINK cables. The Device Index is set via rotary switches on the IOTA base (range 001-510), and the primary controller must be set to an odd number.
• Why is my CC-PCNT02 failing to sync with its redundant partner?
  Check whether the primary and backup controllers are connected to the same IOLINK cable, whether the primary index is odd and the backup is the next consecutive even number, and whether the "Controller is Redundant" option is checked in Control Builder.
• What does a red LED on the module indicate?
  A red LED on the controller itself typically indicates a hardware fault or critical system error. A red LED on a counting I/O module usually indicates a communication fault with the controller.
