12.4.9 Communication format setting [D8370, 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 ch0 is used, D8370 sets the communication format.
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 D8370, D8400.
*1.
Make sure to set as "0" when using computer link.
*2.
In RS2 instruction, up to four headers and up to four terminators can be set.
*3.
The control line is not available in FX
3G
, FX
3GC
PLCs when ch0 is used. Set "(1, 1, 1)".
*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.
*5.
Make sure to set as "0" when using non-protocol communication.
2. Cautions on use
• In FX
3S
, FX
3U
and FX
3UC
PLCs, the communication format can be set using parameters.
• Even if the communication format is changed while the RS2 instruction is being driven, it is not reflected.
• In FX
3G
and FX
3GC
PLCs, the communication format can be set only for ch1 and ch2 using parameters.
