Compatible Replacement & Equivalent Models
When the MW100-E-1H is unavailable or discontinued, the following models may serve as functional replacements or equivalents depending on your system configuration:
- YOKOGAWA MW100-E-1H/M — Extended memory variant; direct functional equivalent with additional data storage capacity.
- YOKOGAWA MW100-E-2H — Dual-port Ethernet variant; suitable when redundant network paths are required.
- YOKOGAWA MW100-E-1H/C — Conformal-coated version for harsh environments; same electrical specifications.
- YOKOGAWA MX100 Series Ethernet Modules — Next-generation platform; requires MX100 mainframe; not a drop-in replacement but functionally equivalent for new installations.
- Third-party Modbus/TCP Ethernet Gateways — For legacy system integration where original YOKOGAWA modules are unavailable; protocol compatibility must be verified.
Note: Always verify firmware version, backplane compatibility, and communication protocol support before substituting modules. Contact Konmask.com for pre-sales compatibility verification.

Selection Guide
Use the following criteria to determine whether the MW100-E-1H is the right module for your application:
- ✔ Choose MW100-E-1H if: You have an existing MW100 DAQ Station and require standard single-port Ethernet connectivity with Modbus/TCP support.
- ✔ Choose MW100-E-1H/M if: You need extended onboard data storage in addition to Ethernet communication.
- ✔ Choose MW100-E-2H if: Your application requires dual Ethernet ports for network redundancy or segmentation.
- ✔ Choose MW100-E-1H/C if: Your installation environment involves corrosive gases, high humidity, or extreme dust exposure.
- ✔ Consider MX100 Series if: You are designing a new system and require higher channel density or advanced features — plan for a full platform migration.

Replacement & Compatibility FAQ
Q: Is the MW100-E-1H still in production?
A: YOKOGAWA periodically updates the MW100 platform. Contact us to confirm current availability and lead times.
Q: Can I use a third-party Ethernet module in the MW100 mainframe?
A: The MW100 backplane uses a proprietary slot interface. Third-party modules are generally not compatible. Only YOKOGAWA-designed MW100 communication modules are supported.
Q: What is the difference between MW100-E-1H and MW100-E-2H?
A: The MW100-E-1H has a single Ethernet port; the MW100-E-2H provides dual ports for network redundancy. Both support the same protocols.
Q: Does the MW100-E-1H support Modbus/TCP?
A: Yes. The MW100-E-1H natively supports Modbus/TCP, enabling integration with SCADA systems and PLCs from Siemens, Rockwell, Mitsubishi, and others.
Q: Can I upgrade from MW100 to MX100 using the same modules?
A: No. The MX100 is a different platform with a different backplane. Modules are not interchangeable between MW100 and MX100 mainframes.
Q: Do you offer expedited shipping for urgent replacements?
A: Yes. Express shipping via DHL Express or FedEx Priority is available. Contact support@konmask.com for urgent orders.
