I think,many plc user of omron should be has question for what is the different between CPM2A and C200HX-CPU44 of omron controller.

There are 2 different Ethernet adapter for PLC Series CP.
1 is designed CP1W-CIF41 Omron Japan, the other is the U.S. Omron developed CP1W-ETN01-USA.
They have slightly different data, but are very similar in concept.
One of the two devices is essentially an Ethernet serial converter, so that both some limitations on an Ethernet module on the bus directly to the PLC CPU as CS and CJ Ethernet modules are compared.

The CP1W-CIF41 uses the protocol Toolbus on the PLC, and has a maximum length frame of ~ 1000 bytes.
The CP1W-ETN01 US-CV-mode uses the Host Link protocol on the PLC, and has a maximum length frame of ~ 500 bytes. (more…)
