Precautions for Correct Use Precautions for Correct Use
The differences between the Ethernet Option Board and the CS/CJ series Ethernet Unit are as follows.
• Connect with the CPU Unit by the Host Link (serial communications) whose internal baud rate is 115.2
kbps.
• The size of communications buffers is 8K bytes, one fifty of that of the CS/CJ series Ethernet Unit.
Therefore, the communication performance is slower than the CS/CJ series Ethernet Unit.
Refer to the following processing time (Netwok delay is not included), when accessing to the CP-series CPU
Unit through the Ethernet Option Board.
When accessing to the CP1E CPU Unit and reading 269 words from the DM area, if the cycle time of the
CPU Unit is 10 ms, the processing time will be more than 225 ms and less than 356 ms.
For the CS/CJ series CPU Unit who installs the Ethernet Unit, when executing the same task, the process-
ing time will be approximately 20 ms, up to 17 times faster.
