2. Cautions on use
Do not use both the parameters and communication format setting devices (D8120 or D8420) at the same
time. If the communication format is set using both methods at the same time, priority is given to the setting
using parameters.
When setting the communication format device (D8120) in an FX
0N
PLC, set the communication setting
latched (battery backed) device (M8120) to ON.
When using computer link, make sure to set the header (b8) and terminator (b9) to "not provided". And set the
protocol (b14) to "used".
If the communication format is set using the special data register, the setting becomes valid when the power
is turned ON after the setting is written to the special data register.
