(3) The rising edge detection command of the normally open contact connected between the LDP (taking the rising edge command) and the left bus is only connected for one scanning cycle (4) when the rising edge of the positioning element is pointed (from off to on). The falling edge detection command of the normally closed contact connected between the LDF (taking the falling edge command) and the left bus. (5) Out (output command) command to drive the coil, also known as output command fetch command and output command instructions: 1) ld and LDI commands can be used to input the contacts connected to the left bus, and can also cooperate with anb and orb commands to realize block logic operation. 2) LDP and LDF commands only maintain the connection of a scanning cycle when the corresponding components are valid. 3) The target components of LD, LDI, LDP and LDF instructions are x, y, m, t, C and S; 4) The out command can be used several times continuously (equivalent to coil parallel connection). For timers and counters, the constant K or data register should be set after the out command. 5) the target components of the out command are y, m, t, C and s, but it cannot be used for a normally open contact series connection command of X (1) and (and command) to complete the logical "and" operation. (2) Ani (and reverse command) a normally closed contact is connected in series to complete the logical "and not" operation. (3) The rising edge of the andp detects the serial connection command. (4) Instructions for the use of andf falling edge detection series connection command contact series connection command: 1) and, ani, andp, andf all refer to the command of single contact series connection. The number of series connections is unlimited and can be used repeatedly. 2) the target components of and, ani, andp, andf are x, y, m, t, C, and s. 3) Driving Y4 through the contact of T1 after the out M101 command is called continuous output. Contact parallel instruction (or/ori/orp/orf) (1) or (or instruction) is used for parallel connection of single normally open contact to realize logical "or" operation. (2) Ori (or not command) is used for parallel connection of single normally closed contact to realize logical "or not" operation 3) ORP rising edge detection of parallel connection command. (4) Instructions for use of ORF falling edge detection parallel connection command contact parallel command: 1) or, ori, ORP and ORF commands refer to the parallel connection of a single contact. The left end of the parallel contact is connected to LD, LDI, LDP or LPF, and the right end is connected to the right end of the contact corresponding to the previous command. The number of continuous use of the contact parallel command is unlimited; 2) The target components of or, ori, ORP and ORF instructions are x, y, m, t, C and s. Block operation command (ORB / anb (1) orb (block or command) is used for parallel connection between circuits with two or more contacts connected in series. Use of orb instruction 1) when several series circuit blocks are connected in parallel, LD or LDI instruction should be used at the beginning of each series circuit block; 2) There are multiple circuit block parallel circuits. If the orb command is used for each circuit block, the number of circuit blocks in parallel is unlimited; 3) Orb instruction can also be used continuously, but this programming method is not recommended. LD or LDI instruction shall not be used more than 8 times, that is, orb can only be used continuously for less than 8 times (2) anb (block and instruction) for series connection between circuits with two or more contacts connected in parallel. Instructions for using anb command: 1) when parallel circuit blocks are connected in series, LD or LDI command is used at the beginning of parallel circuit blocks; 2) When multiple parallel circuit blocks are connected in series with the previous circuit in sequence, there is no limit on the number of times anb commands can be used. Anb can also be used continuously, but like orb, it is used less than 8 times. Set and reset instruction (set/rst1) set (set instruction) its function is to set and maintain the operated target element (2) rst (reset instruction) to reset and maintain the reset state of the operated target element. The use of set and RST commands. When x0 is normally open and connected, Y0 changes to the on state and remains in this state. Even if x0 is disconnected, Y0's on state remains unchanged; Only when X1 is normally open and closed, Y0 becomes off and remains. Even if X1 is normally open and closed, Y0 is still off. The target components of set and RST instructions are y, m and S. the target components of RST instructions are y, m, s, t, C, D, V and Z. Rst instruction is often used to clear the contents of D, Z and V, and to reset the integrating timer and counter. 2) For the same target component, set and RST can be used multiple times, and the order can be arbitrary, but the last executor is valid. Differential command (pls/plf) (1) PLS (rising edge differential command) generates pulse output of one scanning cycle at the rising edge of the input signal (2) PLF (falling edge differential command) generates pulse output of one scanning cycle at the falling edge of the input signal. Use the differential command to detect the edge of the signal, and control the status of Y0 through the set and reset commands. Instructions for the use of PLS and PLF commands: 1) the target components of PLS and PLF commands are y and m; 2) When using PLS, the target element is on only in one scanning cycle after the drive input is on, and M0 is on only in one scanning cycle when the normally open contact of x0 changes from off to on; When PLF command is used, it is only driven by the falling edge of the input signal, and the others are the same as pls. Master command (mc/mcr) 1) MC (master command) is used for connection of common series contacts. After MC is executed, the left busbar moves behind the MC contact. 2) MCR (master control reset instruction) is the reset instruction of MC instruction, that is, use MCR instruction to restore the position of the original left bus. In programming, it often happens that multiple coils are controlled by one or a group of contacts at the same time. If the same contacts are connected in series in the control circuit of each coil, it will occupy a lot of storage units. This problem can be solved by using the master command. MC and MCR instructions use MC N0 M100 to realize the right shift of the left bus, so that Y0 and Y1 are under the control of x0, where N0 represents the nesting level, and there is no limit to the number of times N0 can be used in the non nested structure; Use MCR N0 to restore to the original left bus state. If x0 is disconnected, the instruction between MC and MCR will be skipped and executed downward. Instructions for use of MC and MCR commands: 1) the target components of MC and MCR commands are y and m, but special auxiliary relays cannot be used. MC accounts for 3 procedure steps and MCR for 2 procedure steps;) The main control contact is perpendicular to the general contact in the ladder diagram. The main control contact is a normally open contact connected to the left bus and is the main switch that controls a group of circuits. The contacts connected with the main control contacts must be commanded by LD or LDI. 3) When MC refers to disconnection, the integrating timer, counter and components driven by reset / set command in MC and MCR remain unchanged. For non integrating timers and counters, components driven by out command will be reset. When x0 is disconnected in 22, Y0 and Y1 will become off.
