Description
HIMA X-COM02 Communication Module
Product Overview
The HIMA X-COM02 designation requires particular attention during procurement. HIMA’s official HIMax documentation identifies X-COM 01 as the HIMax communication module and describes it as providing four RJ45 interfaces and two 9-pin D-Sub interfaces, with support for up to six communication protocols. HIMA’s certification and firmware documentation also identifies X-COM 01 E as an enhanced-memory communication module. I could not verify an official HIMA HIMax hardware designation called X-COM02 in the available manufacturer documentation.
That distinction matters for a legacy safety-system replacement. A part number that differs by only one digit should never be treated as interchangeable in a certified SIS. The HIMax communication module sits in the central system architecture alongside the X-CPU and X-SB modules, and its operating-system compatibility is part of the overall configuration. HIMA’s published release information lists dedicated communication-module operating systems for X-COM 01 and X-COM 01 E rather than an X-COM02 device.
For that reason, HIMA X-COM02 should currently be handled as a part-number verification case rather than assigned an unverified channel count, protocol list, supply voltage, firmware revision, or environmental rating. The correct engineering approach is to compare the physical module marking, HIMA order number, hardware revision, host HIMax system, and installed SILworX/operating-system version before approving the replacement.
Product Introduction
Legacy HIMA systems can contain similar-looking communication hardware with materially different firmware and certification boundaries. The X-COM02 designation should therefore be checked against the installed HIMax hardware rather than matched by appearance alone.
For a HIMA safety-system upgrade or legacy replacement, the first verification target should be the complete nameplate and order information. HIMA’s official documentation confirms X-COM 01 and X-COM 01 E as HIMax communication-module variants; an unverified X- should not be presented as a drop-in equivalent.

Major Features / Practical Advantages
HIMax Communication Architecture
In a HIMax installation, communication hardware is part of the safety-system architecture rather than simply a generic Ethernet interface. HIMA lists the X-COM 01 alongside the X-CPU processor modules and X-SB system-bus module as central HIMax hardware.
That means replacement selection needs to consider the complete controller configuration. The communication module’s hardware generation and operating system must remain compatible with the rest of the HIMax installation.
Multiple Communication Interfaces
For the verified X-COM 01, HIMA documents four RJ45 interfaces and two 9-pin D-Sub interfaces. The same manufacturer document states that the module can support up to six different protocols.
Those specifications should not automatically be assigned to an X-. If the physical module really carries an X- marking, its exact HIMA order number should be established before these interface specifications are used in an engineering document.
Firmware Is a Procurement Issue
HIMA maintains dedicated operating-system images for its communication modules. The release documentation identifies X-COM 01 with a HIMax communication operating system and separately identifies X-COM 01 E with its own operating-system family.
This is important when purchasing a surplus or legacy spare. Hardware compatibility alone does not establish software compatibility. The installed HIMax operating-system version, loader, hardware revision, and SILworX project should be checked as part of replacement planning.
Safety-System Application
HIMax is used for safety applications including emergency shutdown, fire and gas, high-integrity pressure protection, pipeline management, turbomachinery control, burner and boiler protection, and interlocking.
A communication module in such an architecture should therefore be evaluated as safety-system hardware. It should not be substituted with a generic industrial Ethernet card simply because the connector arrangement appears similar.

FAQ
What is HIMA X-?
The designation X- cannot currently be confirmed as an official HIMax product designation from HIMA’s available manufacturer documentation. HIMA’s official documentation identifies X-COM 01 and X-COM 01 E as HIMax communication modules.
Is X- the same as X-COM 01?
It should not be assumed to be. The available HIMA documentation explicitly identifies X-COM 01 as the HIMax communication module. A one-character difference in a safety-system part number is sufficient reason to verify the hardware before substitution.
Does HIMA X-COM 01 support multiple protocols?
Yes. HIMA’s technical facts document states that the X-COM 01 has four RJ45 ports, two 9-pin D-Sub interfaces, and supports up to six different protocols.
Can I hot-swap X-?
Do not assume hot replacement for an unverified X- designation. In a HIMax safety system, module replacement must follow the applicable HIMA maintenance procedure and the site’s safety-management process.
Does X- support firmware V3.1?
There is not enough verified manufacturer information to associate firmware V3.1 with an X-. HIMA’s published documentation uses specific operating-system identifiers for X-COM 01 and X-COM 01 E.
Can an X- be used as a legacy replacement for X-COM 01?
Not without verification. Check the complete HIMA order number, hardware revision, system generation, operating-system compatibility, connector arrangement, communication configuration, and SILworX project before treating one module as a replacement for another.
What should I verify when purchasing a New Surplus X-?
Request clear photographs of the front label, complete HIMA order number, hardware revision, serial/nameplate information, and connector side. If the label actually reads X-COM 01 or X-COM 01 E, use that exact designation when checking compatibility.
Procurement Note
For , the most important procurement issue is identification accuracy rather than a claimed specification sheet. HIMA’s own documentation supports X-COM 01 and X-COM 01 E as HIMax communication-module designations, while I could not verify X- as an official HIMax module designation.
Do not approve a replacement solely from a reseller title or a photograph that does not show the complete label. Verify the exact catalog/order number, hardware revision, host HIMax controller generation, installed communication configuration, operating-system version, and SILworX project compatibility.
For a safety-critical installation, that extra verification step is worth more than a specification table filled with assumptions.
