Frequently Asked Questions (FAQ)

Q1: What is the purpose of the TB850, TB807, and TB852 terminators in the PM861K01 kit?
A1: These terminators are used for proper electrical termination of the CEX-Bus, ModuleBus, and RCU-Link to ensure signal integrity and reliable communication.

Q2: Can the PM861K01 operate in a redundant CPU configuration?
A2: Yes, it fully supports redundancy via the RCU-Link. Two PM861 units can operate in a primary-backup mode with automatic switchover.

Q3: Is the PM861K01 suitable for safety-critical applications?
A3: The PM861 itself is not SIL-certified. For safety-critical (SIL2/SIL3) applications, use PM865 or PM865/SM810 combination.

Q4: Can the included TP830 baseplate be used for other CPU types?
A4: Yes, TP830 is compatible with other PM8xx series CPUs, including PM860, PM864, and PM865.

Q5: How do I connect S800 I/O modules to the PM861K01?
A5: Connect S800 I/O modules directly to the Electrical ModuleBus on the TP830 baseplate using a ModuleBus cable with TB820 modems if needed.

Q6: What types of communication modules are supported on the CEX-Bus?
A6: The CEX-Bus supports modules such as CI854 (PROFIBUS), CI860 (FF HSE), CI867 (Modbus TCP), and others.

Q7: What is the function of the INIT push button on the PM861?
A7: The INIT button is used to reset the processor or initiate firmware download and recovery operations.

Q8: How is memory backed up in the PM861K01 system?
A8: The system includes internal memory backup supported by an external battery via the TP830 baseplate to maintain RAM and RTC data during power loss.
