FAQ

1. What is the main function of the HIMA X-COM 01 985260000?

The HIMA X-COM 01 is a communication module designed for the HIMax programmable electronic system (PES). It provides communication between the HIMax safety system and external control, monitoring, automation, and plant-level systems. The module provides four Ethernet interfaces and two fieldbus interfaces, allowing different communication technologies to be integrated into the same HIMax system. It can handle safety-related communication such as SafeEthernet as well as standard industrial protocols such as Modbus TCP, PROFINET/PROFIsafe, PROFIBUS DP, and Modbus RS485, depending on the installed configuration and activated protocol options.

2. What is the difference between X-COM 01 and ordering number 985260000?

X-COM 01 is the module model designation, while 985260000 is the ordering number for the standard X-COM 01 configuration. The standard X-COM 01 is supplied without optional fieldbus submodules. When one or more fieldbus submodules are installed, the product designation and ordering number change to the corresponding X-COM 010 XY configuration. Therefore, both the model and ordering number should be checked when purchasing or replacing a communication module to ensure that the hardware configuration matches the existing HIMax system.

3. How many Ethernet ports are available on the X-COM 01?

The X-COM 01 provides four RJ-45 Ethernet interfaces. These ports support 10/100 Mbit/s Ethernet with auto-negotiation and auto-crossover functionality. The four Ethernet ports are internally connected through an integrated switch, allowing the communication module to connect multiple Ethernet devices within the HIMax network architecture. Depending on the configured communication protocols, the interfaces can be used for SafeEthernet and standard Ethernet-based protocols. Proper IP addressing, subnet configuration, and network topology should be established during commissioning to ensure stable communication with external systems.

4. Which communication protocols can be used with the X-COM 01?

The X-COM 01 supports multiple communication options. Depending on the system configuration and activated software options, it can simultaneously process up to six protocols. Supported options include SafeEthernet, Modbus TCP Master/Slave, PROFINET and PROFIsafe, Modbus RS485 Master/Slave, PROFIBUS DP Master/Slave, TCP Send/Receive, ComUserTask, SNTP, and HART over IP. The actual protocol availability depends on the hardware configuration, installed fieldbus submodules, and software configuration. When configuring a safety system, engineers should verify that the required protocol is supported and correctly activated before commissioning the communication network.

5. Does the standard X-COM 01 include fieldbus submodules?

No. The standard X-COM 01 with ordering number 985260000 is the communication module without fieldbus submodules. Optional fieldbus interfaces can be provided as part of other X-COM 010 XY configurations. HIMA documentation specifies that fieldbus submodules are selected when ordering and are not intended to be retrofitted by unauthorized personnel. If a system requires PROFIBUS, Modbus RS485, RS232, RS422, or another supported fieldbus interface, the correct hardware configuration should be selected when ordering the communication module. This is important when replacing an existing module because a visually similar X-COM variant may have a different hardware configuration.

6. Does the X-COM 01 require a separate connector board?

Yes. The X-COM 01 forms a functional unit with the X-CB 001 02 connector board, which is purchased separately. The connector board provides the physical interface connections between the communication module and external Ethernet or fieldbus wiring. Before installing the X-COM 01, the appropriate connector board should be correctly installed in the designated position. If the connector board is missing, incorrectly installed, or damaged, the communication interfaces cannot be connected correctly to the external system. When replacing an existing module, the condition and compatibility of the connector board should therefore be checked as part of the maintenance procedure.

7. What should be checked if the Ethernet communication of the X-COM 01 is unstable?

Troubleshooting should begin with the Ethernet connection and LED status indicators. Check the RJ-45 connectors, Ethernet cables, network switches, and the connected communication partners. The Ethernet LEDs can provide useful information about link status and communication activity. If an IP address conflict occurs, the Ethernet indicators can also show an abnormal status. The network configuration should then be checked, including IP address, subnet mask, gateway, protocol configuration, and communication parameters. If the physical link is stable but application communication remains unavailable, the configured protocol and corresponding software settings should be reviewed. For safety-related communication, the SafeEthernet configuration and redundant communication paths should also be checked according to the system design.

8. What are the power and environmental requirements of the X-COM 01?

The X-COM 01 operates from a 24 V DC supply with an allowed tolerance of approximately -15% to +20%. Its specified current consumption is approximately 0.25 to 0.46 A. The normal operating temperature range is 0 to +60 °C, while the storage temperature range is -40 to +85 °C. The module supports up to 95% relative humidity without condensation and has an IP20 protection rating. During installation, the module should be installed inside a suitable control cabinet or protected enclosure that maintains the specified environmental conditions. Stable power and adequate environmental protection are especially important in safety-related HIMax installations because communication failures can affect system availability and may generate diagnostic or fault conditions.
