The RS2 instruction is dedicated to the FX
3S
, FX
3G
, FX
3GC
, FX
3U
and FX
3UC
PLCs.
In FX
3G
, FX
3GC
PLCs, the RS2 instruction allows communication using three channels at the same time.
In FX
3U
, FX
3UC
PLCs, the RS2 instruction allows communication using two channels at the same time.
1) Up to 4096 points of data can be sent, and up to 4096 points of data can be received. In the case of FX
2N
and FX
2NC
PLCs, make sure that the total number of sent and received data is 8000 points or less.
2) Data transfer is enabled when the connected equipment supports non-protocol serial communication.
3) The applicable total extension distance is 15m (49' 2") maximum in accordance with RS-232C
