The following devices are used in the communication setting.
When using communication port ch0, set D8370.
When using communication port ch1, set D8400.
When using communication port ch2, set D8420.
1. D8370, D8400 and D8420 (communication format)
By setting values to D8400 or D8420, the data length, parity, baud rate, etc. can be set.
The table below shows the contents of D8400 and D8420.
*1.
In RS2 instruction, up to four headers and up to four terminators can be set.
*2.

PLCs when ch0 is used. Set "(1, 1, 1)".
*3.
Make sure to set as "0" when using non-protocol communication.
*4.
When executing non-protocol communication using RS2 instruction, add the sum check code after the
