1) transmitted the instruction MOV instruction is to transfer the data in the source operand to specify the number of target actions, namely [s] → [d].Figure 1 routing instructions form2) instruction MOV instructions figure. When X0=ON, and the source operand [s] constant K100 is transmitted to the target actions in element D10. When the instruction … Continue reading Mitsubishi FX series PLC transmitted instruction
(1) shall comply with heat in the ladder diagram language syntaxRelay diagram, for example, contacts can be placed online on the left, or you can put the right side of the coil, but in a ladder diagram, coils and output class instruction (such as SET and application instructions and RST) must be placed in the … Continue reading Relay diagram design
FX series timers for a maximum time of 3 276.7s, if you need more time, you can use the circuit shown in Figure 1. When OFF is X2, T0, and C0 is in reset State, they do not work. X2 for ON Shi, its often open touch points connected, T0 began timing, 3000s Hou 100ms … Continue reading Timed extension of FX series PLC programming
(1) instruction MOV (d) MOV (p) order number is FNC12, which is the function of the source data to the specified destination. As shown in Figure 1, when ON is X0, then the [s.] K100 delivered to the destination of the data in the operation elements [d.] The D10. At the time of order execution, … Continue reading PLC transmit instruction MOV SMOV CMOV BMOV FMOV
Monitor the WDT timer instructions (p) number is FNC07 no operands, possession of 1 program step. WDT instruction function is to refresh the watchdog timer of the PLC.FX series PLC watchdog timer default value is 200ms (D8000 could be used to set), normal PLC scan period is less than the scheduled time. If outside interference … Continue reading PLC watchdog timer instructions WDT
Instruction FEND number main program ends FNC06, no operation, taking up 1 program step. FEND main program ends, as when performing to FEND, PLC input/output processing, watchdog timer, refresh, complete and return the start step.FEND instruction should be used note:1) subroutines and interrupts service routines should be placed after the FEND;2) subroutines and interrupts service … Continue reading PLC program instructions FEDND
CALL subroutine call instruction's number is FNC01. P0~P127 the operands, this instruction takes 3-program step.SRET subroutine return directive number FNC02. No operands, occupies 1 program step.As shown in Figure 1, if X0 connected, go to the label P10 to execute subroutines. When a SRET instruction is executed, it returns to the next step of the … Continue reading PLC subroutine call and return instructions
FX2NC has very high performance volume and communication capabilities, can be installed to a PLC in a much smaller space than standard. I/O connectors wiring costs can be reduced, saving connection time. I/O point numbers can be extended to 256, optional real-time clock, can connect up to 4 specific modules. Take advantage of built-in features, … Continue reading FX2Nc series PLC performance profile (basic unit, extension)
