2.3.3 Other cautions
1. For FX , FX
1S 1N
1) Verify that the communication format is in the initial status (D8120 = K0).
Check the communication parameters using the peripheral equipment.
If the communication is set so that non-protocol procedure (RS instruction) or a dedicated protocol is
used, clear the setting to "0" using the peripheral equipment.
2) If RS instruction is used in the program, delete it, turn OFF the PLC power, and then turn it ON again.
2. For FX (Ver. 2.00 or later) and FX
2N
1) Verify that the communication format is in the initial status (D8120 = K0).
Check the communication parameters using the peripheral equipment.
If the communication is set so that non-protocol procedure (RS instruction) or a dedicated protocol is
used, clear the setting to "0" using the peripheral equipment.
2) If RS instruction is used in the program, do not execute it. If it is executed, the PLC operates according to
RS instruction.
3. For FX (Ver. 3.00 or later) and FX
2N
1) Verify that the communication format is in the initial status (D8120 = K0).
Check the communication parameters using the peripheral equipment.
If the communication is set so that non-protocol procedure (RS instruction) or a dedicated protocol is
used, clear the setting to "0" using the peripheral equipment.
2) If RS instruction is used in the program, do not execute it. If it is executed, the PLC operates according to
RS instruction.
3) If EXTR instruction is used in the program, delete it, turn OFF the PLC power, and then turn it ON again.
4. For FX and FX
3U
1) Verify that the communication format for the communication port used in programming communication is
set correctly (D8120, D8400, D8420 = K0).
Check whether the communication parameters are set correctly using the peripheral equipment.
2) Verify that the RS or RS2 instructions are not executed in the program for the communication port used in
programming communication.
Do not execute RS and RS2 instructions.
3) If an inverter communication instruction is used in the program for the communication port used in
programming communication, delete it, turn OFF the PLC power, and then turn it ON again.
