Advanced Function <strong>Instruction</strong>FUN 74 PIMDIOIMMIDIATE I/OFUN 74 PIMDIOLadder symbolReflesh controlEN74P.IMDIOD :N :D : Starting number of I/O points to be refreshedN : Number of I/O points to be refreshedOperandRangeX Y KXn ofMainUnit.Yn ofMainUnit.D ○ ○N1∣36○●●●For normal PLC scan cycle, the CPU gets the entire input signals before the program is executed, and thenperform the executing of program based on the fresh input signals. After finished the program execution theCPU will update all the output signals according to the result of program execution. Only after the completescan has been finished will all the output results be transferred all at once to the output. Thus for the inputevent to output responses, there will be a delay of at least 1 scan time (maximum of 2 scan time). With thisinstruction, the input signals or output signals specified by this instruction can be immediately refresh to getthe faster input to output response without the limitation imposed by the scan method.When refresh control "EN" = 1 or "EN↑" ( P instruction) has a transition from 1 to 0, then the status of Ninput points or output points (D~D+N-1) will be refreshed.The I/O points for FBs-PLC's immediate I/O are only limited to I/O points on the main unit. The table belowshows permissible I/O numbers for 20, 32, 40 and 60 point main units:Main-unit typePermissible numbers20 points 32 points 40 points 60 pointsInput signals X0~X11 X0~X19 X0~X23 X0~X35Output signals Y0~Y7 Y0~Y11 Y0~Y15 Y0~Y23●●If the intended refresh I/O signals of this instruction is beyond the range of I/O points specified on abovetable then PLC will be unable to operate and the M1931 error flag will be set to 1. ( for example, if in aprogram, D=X11, N=10, which means X11 to X20 are to be immediately retrieved. Supposing the main unitis FBs-32MA, then its biggest input point is X19, and clearly X20 has already exceeded the main unit's inputpoint number so under such case M1931 error flag will be set to 1).With this instruction, PLC can immediately refresh input/output signals. However, the delay of the hardwareor the software filter impose on the I/O signals still exist. Please pay attention on this.7-55

According to the key-in sequence (ON) of these input points, it is possible to enter 4 or 8decimal numbers into the registers specified by D.• When input control "EN" = 1, this instruction will monitor the10 input points starting from IN and put the correspondingnumber into D register while the key were depressed. It willwait until the input point has released, then monitor the next"ON" input point, and shift in the new number into D register(high digit is older than low digit ) . For the 16-bit operand, Dregister can store up to 4 digits, and for the 32-bit operand 8digits may be stored. When the key numbers full fill the Dregister, new key-in number will kick out the oldest keynumber of the D register. The key-in status of the 10 inputpoints starting from IN will be recorded on the 10corresponding coil starting from KL. These coils will set to 1while the corresponding key is depressed and remainunchanged even if the corresponding key is released. Untilother key is depressed then it will return to zero. As long asany input point is depressed (ON), then the key-in flag KPRwill set to 1. Only one of IN0~IN9 key can be depressed atthe same time. If more than one is pressed, then the firstone is the only one taken.
