Installation Guide

Follow these steps to install the HIMA X-CPU 01 correctly. First, insert the module into a supported base plate slot in your HIMax rack. Second, connect the 24 VDC supply with proper SELV/PELV isolation. Third, attach Ethernet cables to the four RJ-45 ports for safeethernet communication. Fourth, configure IP addresses and subnet masks using HIMax engineering tools. Fifth, load up to 32 user programs into the 128 MB Flash memory. Sixth, set up redundancy with up to 3 additional X-CPU 01 modules if needed. Seventh, verify the safety time meets your application requirements (≥20 ms). Finally, test event storage by generating sample CPU and I/O events.

Frequently Asked Questions (FAQ)

Q1: What is the maximum number of user programs the HIMA X-CPU 01 can run?
A: The X-CPU 01 processes up to 32 user programs simultaneously. Each program gets 1023 kB of program memory and 1023 kB of data memory. The total combined memory for all programs is 10 MB less 4 kBytes for CRC checking.

Q2: Can I use multiple X-CPU 01 modules in a redundant configuration?
A: Yes, you can add up to 3 additional X-CPU 01 modules for redundancy. The system handles automatic failover between processor modules. This provides high availability for critical safety applications.

Q3: What communication protocols does the HIMA X-CPU 01 support?
A: The module supports safeethernet for safety-related communication. It also supports PADT (Programming and Diagnostic Tool) protocol. The four RJ-45 ports run at 10/100/1000 Base-T with auto negotiation and auto crossover.

Q4: How does the HIMA X-CPU 01 handle date and time during power loss?
A: A gold capacitor buffers the date and time during temporary power interruptions. This maintains time stamps for stored events without a battery. For extended power loss, the system may require time re-synchronization after restart.

Q5: What is the safety time of the X-CPU 01 for SIL 3 applications?
A: The safety time is at least 20 ms but depends on your application configuration. Longer user programs or more I/O modules increase the safety time. Refer to the HIMax Safety Manual (HI 801 003 E) for detailed calculation methods.
