INTRODUCTION
The M4SENET-100 is an Ethernet network interface card designed for Opto 22’s legacy M4-series industrial controllers, such as the SNAP-LCM4 and the M4RTU. The key advantage of the M4SENET-100 is that it operates on standard Ethernet networks using standard TCP/IP transport. A separate I/O or control network is not required for the control system. (Note: M4-series controllers are legacy products and not recommended for new development. For new development, use SNAP PAC programmable automation controllers.)

Differences from Previous M4-Series Ethernet Cards
The M4SENET-100 differs from previous Ethernet cards used with M4-series controllers as follows: • The M4SENET-100 is far faster than previous cards (100 Mbps rather than 10 Mbps). • The M4SENET-100 can be easily diagnosed and maintained using Telnet. • Previous cards supported both NetBIOS and TCP/IP; the M4SENET-100 supports TCP/IP only. • The M4SENET-100 card requires FactoryFloor version 3.0 or greater. FactoryFloor 3.0 and above do not support the older M4SENETU or M4SENETC Ethernet cards.
