PAGE 49
1.4 Special Functions 1.4.3 Constant Scan Time Mode This function executes a program while keeping the scan time at a constant value which usually changes based on the processing contents. This section describes how to set this function. Though the scan time changes usually depending on the processing contents, it can be kept at a constant value by using this function. This function can be used to acquire data from external equipment at a constant time interval.
PAGE 50
1.4 Special Functions 1.4.4 Output Disabled Function This function disables outputs from each unit in RUN mode without regard to the program used. By disabling external outputs, the program can be debugged while external equipment is connected, even when output of signals to the external equipment is not desired. ■ Setting procedure When special utility relay 2300 turns ON, all outputs from all output relays (0500 to 0915) to the outside are cleared after 1 scan is finished.
PAGE 51
1.5 Extended Ladder Diagrams 1.4.6 Contact Comment Save Function • This function transfers contact comments to the Visual KV Series using the "KV IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software. • The Visual KV Series can store not only programs but also comments registered to each contact using the "KV IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software. A program may not be easy to understand if only device Nos. are used.
PAGE 52
1.4 Special Functions 1.4.7 Special Functions KV-300 PLC only Constant Scan Time Mode In this mode, operation can take place according to a preset scan time (in ms). ■ Setting Write the desired scan time into TM29 (temporary data memory), then turn on special utility relay No. 2303. The scan time can also be written into TM31. Specify a scan time in increments of 10 ms (a value of less than 10 ms is invalid). Here, write a value into TM equivalent to 10 times the scan time.
PAGE 53
1.5 Extended Ladder Diagrams 1.5 Extended Ladder Diagrams This section describes KEYENCE’s unique extended ladder diagram. 1.5.1 Features of Extended Ladder Diagrams The extended ladder diagram is a programming method developed to reduce problems related to design, testing, operation, and maintenance of programs. In a conventional ladder diagram, output instructions can be written only on the right side of a ladder diagram.
PAGE 54
1.5 Extended Ladder Diagrams 1.5.2 Advantages of Extended Ladder Diagrams The number of lines in a ladder diagram can be reduced. Because both output instructions and input instructions can be written side by side, the number of program lines can be reduced. As the result, the contents of the program can be seen at a glance. Example When DM0000 stores 1000, 0500 turns ON. 2000, 0501 turns ON. 3000, 0502 turns ON.
PAGE 55
1.5 Extended Ladder Diagrams Note: When an extended ladder diagram is used, the number of lines in ladder diagram may be reduced. However, this may not necessarily reduce the number of mnemonics in the program. Conventional ladder diagram 0000 Extended ladder diagram 0500 0000 0500 0501 0501 LD 0000 OUT 0500 OUT 0501 LD 0000 OUT 0500 CON OUT 0501 The CON instruction for connection is added.

3.2 Interrupt Processing 3.2 Interrupt Processing Visual KV Series This section describes interrupt processing. 3.2.1 Interrupt Processing Outline Normally, a PLC processes a ladder sequence program by repeating the steps of input processing, program execution, and output processing. Therefore, signals which are shorter than the scan time cannot be received. When the interrupt processing function is used, a process can be executed at the instant of the interrupt, independent of the scan time.
PAGE 219
3.2 Interrupt Processing 3.2.2 Types of Interrupts Interrupt by an external input This interrupt is executed by input relays 0000 through 0003. Use the special utility relay to specify the polarity of the interrupt factor to a rising or falling edge. Visual KV Series Interrupts can be divided into two types: an interrupt by an external input, and an interrupt by the high-speed counter comparator. This section describes both of these interrupt types.
PAGE 220
3.2 Interrupt Processing CAUTION • • Use SET-RES instructions to turn the special utility relays ON/OFF. The input capture function stores the high-order bit data only when the 24bit high-speed counter is used. The data is undefined when the 16-bit highspeed counter is used. Visual KV Series ➮ "4.4.1 24-bit High-speed Counter" (p. 3-221) • Timing of the input capture execution depends on the input polarity setting specified with special utility relays 2402 through 2405 and 2410 through 2413. 3.2.

3.3 Direct Input/Output 3.3 Direct Input/Output 3.3.1 Direct Input The direct input function is used during interrupt processing. Direct input allows the KV PLC to fetch the input status of the input relays during execution of the interrupt program. Visual KV Series This section describes direct input and output.

6.2 High-speed Counters ■ High-speed counter and counter comparators High-speed counter (CTH1) CTH1 is a 16-bit hardware counter that counts from 0 to 65535. • • • • • KV-10/80 KV-300 • You can specify the operands listed in the table below as the count input. You can specify one operand from the table below. Operand cannot be modified externally during execution of the program. When the external pulse (0004, 0005) is selected, CTH1 is used as a High-speed counter with a response frequency of 30 kHz.
PAGE 303
6.2 High-speed Counters CAUTION • You cannot change operands of the high-speed counters (CTH) during execution of the program. The input time constant of the high-speed counters is usually set to 25 ms. (The HSP instruction is not required.) • High-speed pulses can be counted at up to 30 kHz through external inputs (0004 to 0007) by turning ON special utility relay 2813. (Internal pulses can be counted at up to 50 kHz by turning ON 2813.
PAGE 304
6.2 High-speed Counters Pulse period and width Period and width of the pulse is determined by the period of the internal clock (CTH) used and the preset value of the comparator (CTC). When two counter comparators are used, only the pulse width can be changed while a constant period is maintained.
