Instructions:OR parallel connection, ORI/1 contact instructions.More than 2 contacts connected in series and this series circuit with other circuits connected in parallel, using ORB directives referred to later.OR,ORI is the directive from the start, and the previous step LD,LDI instructions, connected in parallel. No restrictions on the number of parallel connections, but when using the … Continue reading Mitsubishi PLC PLC’s OR, ORI instructions
When M1536-M3071 is used, procedure step 1. Instructions: 1 point of contact with the AND,ANI instruction can be connected in series. Unlimited contacts in series, this directive can be used multiple times. OUT instruction, through contacts on the other coil uses OUT instructions, called vertical output (bottom OUT with OUT Y004 M101) The vertical output, if the order is … Continue reading Mitsubishi PLC Programming FX2N PLC AND, ANI instruction

PLC program can be changed. Now most of the microcontroller (internal FLASH ROM) are available online-burning program, change the program so that it functions with PLC is the same. Of course, there is a curing process. You can no longer change the program like this.PLC chip, its main advantages:1: stable photoelectric isolation due to I/O … Continue reading The difference between the microcontroller and PLC
Implementation calls the system real-time clock clock instructions or according to the need to set the clock, monitoring of the operation of the control system, operation records and real-time time control and is very convenient.Clock instructions there are two: read the real time clock and set the real time clock
pulse output (PLS) instructionsPulse output (PLS) function: enabling effective, check for pulse output (Q0.0 or Q0.1) the special memory (SM), and thenSpecial memory bit pulse action defined
PID command: enables effective, according to the parameters table (TBL) of input measured values, control set value and calculation of PID parameters PID (1) eight PID command can be used in your program, number 0-7, respectively, cannot be repeated. (2) to enable the ENO = 0 error conditions: 0006 (indirect address), SM1.1 (overflow, parameter start addresses or … Continue reading PLC PID instruction
