Prior to Sequence Program Creation 1.5 Prior to Sequence Program Creation 1.5.1 Precautions for sequence program creation POINT •Online change of the sequence program and access to other stations are not allowed. In addition, program read/write from other stations and all PLC memory clear cannot be performed. •Back up the ladder configured with the protective function of GX Developer. If any of the instructions (refer to page 103) and devices (refer to page 3) that cannot be used with the built

Prior to Sequence Program Creation 1.5.3 Sequence program execution key The sequence program execution key (STOP/RUN) of the PLC is switched by turning off/on the SQ signal. POINT •For the terminal used for SQ signal input, set "50" in any of Pr.178 to Pr. 189 to assign the function. •SQ-SD must be shorted to execute the built-in PLC function. CAUTION If the SQ signal is not turned on, the start signal of the inverter is designed to become valid by the factory setting of Pr.415 Inverter operati

Prior to Sequence Program Creation 1.5.4 Sequence program write POINT Sequence program write can be performed in any operation mode. When rewriting the PLC function parameters and sequence program using GX Developer, check the following: 1)Check that the sequence program execution key is in the STOP position (SQ signal is off) (refer to page 7). 2)Check that the inverter is at a stop. 3) Check that the communication specification setting parameters (Pr.117 to Pr.124) are set correctly. If any o
