12.4.9 Communication format setting [D8400 and D8420]
These devices set the communication format.
1. Detailed contents
These devices can set the data length, parity, baud rate, etc.
When communication port ch1 is used, D8400 sets the communication format.
When communication port ch2 is used, D8420 sets the communication format.
The table below shows the contents of the communication format settings. Computer link setting is not
applicable for D8400.
*1. Make sure to set as "0" when using computer link.
*2. Make sure to set as "0" when using non-protocol communication.
*3. In RS2 instruction, up to four headers and up to four terminators can be set.
*4. When executing non-protocol communication using RS2 instruction, add the sum check after the
terminators.
Make sure to set the terminators when adding the sum check.
2. Cautions on use
In FX3U and FX3UC PLCs, the communication format can be set using parameters.
