8 <Toc> <Ind> <. Overview > -. Overview The F3XS4-3N and F3XS4-4N Pulse Input Modules are used with the FA-M3 Rangefree Multi-controller. These modules receive and count voltage pulse signals of to 2 khz. A single F3XS4 module can receive up to 4-channel pulse signals. Features Up to 2-kHz pulse signals can be received with four independent inputs. The input and output terminals are insulated from the internal circuit with photocouplers. A filter can be selected using software to suppress chattering in the input signals. At the count edge, either the rising edge or the falling edge can be selected. Incorporates a 6-bit ring-up counter. The maximum ring size is programmable. Each channel can have two preset values. Generates various types of outputs for combinations of counter values and preset values. A single channel can set up to four external programmable outputs. Generates an interrupt signal when the counter value reaches a preset value or exceeds its maximum value. Counter operation can stop immediately after the counter value returns to zero.

14 <Toc> <Ind> <2. Functions and Operation > Operation of Modules Basic Operation of the Counter The module incorporates a 6-bit ring up-counter to count the number of input pulses: rising inputs from off to on, or falling inputs from on to off. The initial value of the counter is (zero). The counter can count from $ to $FFFF in hexadecimal. If the counter value exceeds $FFFF, the counter will reset to. Select a count edge of either rising or falling to count the number of input pulses (see the input functions). TIP Note that a count value exceeding 32,767 in decimal numbers is expressed as a negative number. Setting the Ring Up-Counter Maximum Value The counter has been set to count $ to $FFFF in hexadecimal as a ring up-counter. However, the maximum count value of the counter can be changed by setting bit at the input data set position and changing preset value 2 to an appropriate value. The ring upcounter maximum set value is given by: Ring up-counter maximum value = (preset value 2) In the above setting, if bit is set, the ring up-counter maximum value will be $FFFF (see the example below). Example: When set value 2 is changed to 5, the ring up-counter is configured as follows: Counter value changes: to to 2 to 3 to 4 to to to 2 to 3 to 4 to to to 2 to... The module detects a preset value when the counter value changes from 4 to 5, and the counter will then reset to. This will configure a to 4 ring up-counter. When the counter is used as a variable ring up-counter, set the ring maximum value greater than 2 (instead of set value 2). If the input pulse frequency is khz or lower, there is no maximum set value limitation on preset value 2. Input pulse frequency Preset value 2 for variable ring up-counter Hz to khz No limitations on preset value 2 to 2 khz Preset value 2 2 TC22.EPS CAUTION To change the ring up-counter maximum value, first stop the counter operation and then reset it. If its maximum value is changed while the counter is operating, operation of the counter will not be assured. IM 34M6H54-E st Edition : Feb.,999-

15 <Toc> <Ind> <2. Functions and Operation > 2-6 Resetting the Counter Resetting the counter means that the counter value returns to (zero). A counter value is reset to by setting the following or if the counter value exceeds its maximum set value. () Resetting by output relays Turning on () output relays Y 36, Y 4, Y 44, and Y 48 (slot numbers for modules are entered in ) related to input channels to 4 will reset their related counter values. (2) Counter value exceeds its maximum value A counter value is reset when it exceeds its maximum value. Counter Enabled and Disabled Operation of the counter is enabled or disabled by setting the following: () Enabling or disabling the counter by output relays To set Counter Enabled or Disabled, use output relays Y 49, Y 53, Y 57, and Y 6 (slot numbers for modules are entered in ) related to input channels to 4. While the output relay related to the input channel is off (), counter operation is disabled. While the output relay related to the input channel is on (), counter operation is enabled. Counter operation in the initial state after the power is turned on is disabled ( stop counter operation ). (2) Automatically stop the counter operation when the counter value is reset. Operation of the counter will stop when the counter value exceeds its maximum value and it is then reset. To stop the counter operation, set bit rather than bit 2 at the data position at which the corresponding input is set. When is set for bit 2, counter operation will continue. To restart the counter operation, turn on the output relays related to the input channels to 4 (Y 35, Y 39, Y 43, and Y 47). IM 34M6H54-E st Edition : Feb.,999-

16 <Toc> <Ind> <2. Functions and Operation > 2-7 Comparing Counter Values with Preset Values This module can provide two preset values ( and 2) per input channel. Counter values are always compared with these preset values. Equal (counter value = preset value) Counter value is smaller than the preset value (counter value < preset value) Counter value is equal to or greater than the preset value (counter value preset value) These comparisons are applied to the input relays X to X 3 (not including X 4, X 8, X 2, X 6, X 9, X 2, X 23, X 24, X 27, and X 28). Input relays X to X 5 (not including X 4, X 8, and X 2) and the corresponding external outputs will be off () if the related output relays Y 33 through Y 47 (not including Y 36, Y 4, and Y 44) change from off () to on (). Preset value 2 is applicable as a maximum value of the ring up-counter. The following gives an example of the coincidence of a counter value and the preset value. When the set value is (initial value): The coincidence is detected when a counter value exceeds its maximum value and returns to. When $FFFF is set for the set value: The coincidence is detected when the counter value exceeds $FFFE and then reaches $FFFF. TIP The coincidence of a counter value with a preset value is detected when the counter value reaches the preset value. However, when an output relay resets a counter value to and the preset value is, or when the set value has been changed to agree with the current counter value, the coincidence will not be detected. Interrupts An interrupt can be allowed in the following states: () When the counter value and preset value coincide; (2) When the counter value and preset value 2 coincide; and (3) When the counter value resets to (zero). This interrupt is allowed by declaring an interrupt. IM 34M6H54-E st Edition : Feb.,999-

17 <Toc> <Ind> <2. Functions and Operation > 2-8 Output to External Output Terminal The module incorporates four independent external output terminals to allow programmable setting of external outputs. Output setting can be made by: () Output selection, and (2) Interconnections between output and input channels. () Output selection Comparing the counter values with preset value or 2 allows any output to be selected from among eight latched outputs or status outputs, as well as counter operating states, output normally on and output normally off. In the initial state, latched outputs, after the counter values have been compared with preset value, will be selected. The latched outputs are turned on when the counter value and preset value or 2 coincide, or when the counter value exceeds a ring up-counter maximum value and is reset. If a user s program turns on a related output relay, the latched output will be off (). The latched output remains on until it is reset. A state output will be on when the comparison operation is true, and will be off when the comparison operation is false. The counter operating status indication output remains on () while the counter is in operation, and remains off () while the counter is not in operation. An output that is normally on or off remains on or off regardless of the counter operating status. (2) Interconnections between input and output channels Up to four remote output terminals can be set to output comparison results obtained in a one-input channel. In the initial state, output is issued to remote output terminals n relating to the input terminal n has been set. For example, comparison results in input channel are issued to remote output terminal. Interconnecting between the input and output channels allows comparison results of counter values in input channel with preset values and 2 to be output to four remote output terminals. However, note that comparison results in input channels 2 through 4 cannot be issued to the remote output terminals. IM 34M6H54-E st Edition : Feb.,999-

18 <Toc> <Ind> <2. Functions and Operation > 2-9 Input filter Pulse input If the module accepts dry-contact input pulses which may contain chattering noise, and the counter counts these pulses, accurate counter values will not be obtained. To obtain a correct counter value, use an input filter. Whether or not an input filter is used for each channel can be set. Input filter constants are common to all input channels. For applications where the modules are used in a location with undesired electrical disturbance, set an appropriate filter using application software. $FFFF Preset value 2 Counter value Preset value Counter enabled Y 49 * Input functionality $ $2 $6 Counter value resets to (zero) X 3 * X3 (reset) Y 35 * F26.EPS *: The relay numbers shown above are for channel.
