  • Page 57: Events

    Chapter 5. FUNCTIONS ■ Events The event configuration data setting allows event types to be set for event outputs 1 to 16. Events are of the following four types: time event, PV event, code event and mode event. Settings are divided into two types of events: segment events and instrument event.
  • Page 58 Chapter 5. FUNCTIONS • An On Time ≥ Off Time setting cannot be made. (See segment 3C in the figure.) Segment On-time No On Time is set. Off-time Output-ON ON=OFF ON>OFF Output-OFF • An On Time or Off Time is valid only within a segment and cannot straddle segments.
  • Page 59 Chapter 5. FUNCTIONS • When there is a G.SOAK wait at the start of a segment and the ON Time is set to 0, the output goes on at start of the G.SOAK wait and the On Time starts as the G.SOAK wait ends.
  • Page 60 Chapter 5. FUNCTIONS • When there is a G.SOAK at the end of the previous segment, the On Time in the next segment is ignored if it is set to 0. (See segments 11 and 12 in the figure.) Thus the ON = 0 of segment 12 is not output at the end of the set time for segment 11, but when the G.SOAK wait ends.
  • Page 61 Chapter 5. FUNCTIONS • Event on delay The number of the event to be delayed and the delay time can be set regardless of event type. The delay turns on the output for the duration of the delay when the event meets the conditions for going from OFF to ON. When this function is combined with the event standby function, the event on delay operates when the standby state is cleared.

  • Page 63 Chapter 5. FUNCTIONS ● PV deviation rate event PV deviation is measured in each sampling cycle set using eventconfiguration while on/off states are determined by comparing event setting deviation rate PVs. PV deviation between sampling cycles is ignored. Event on/off switching is performed according to the sampling cycle.
  • Page 64 Chapter 5. FUNCTIONS ● Code event Several events are used as one group and the number of output points are output as one parallel code number. Assigning code numbers to event outputs has the same effect as increasing the number of physical output points. •...
  • Page 65 Chapter 5. FUNCTIONS • Timed code event This function is a combination of a code event and a time event. The set code value is output at the set time. The number of settings that can be made in the first segment is the same as the number of output points.
  • Page 66 Chapter 5. FUNCTIONS • Program/segment number event A program or a binary coded segment number is set in an event type and the number of output points (1 to 7) is set in auxiliary setting 1. Or a program or a BCD code of the segment number is set in an event type and the number of output points (1 to 8) is set in auxiliary setting 1.

  • Page 68: Pid Group Selection

    Chapter 5. FUNCTIONS ■ PID group selection • ID groups can be selected in two ways: by setting a PID segment or through automatic PID group switching. A PID group segment and automatic PID group switching can also be combined. When a PID group number is set to 0, the setting in the previous segment is continued.

  • Page 69: G.soak (Guarantee Soak)

    Chapter 5. FUNCTIONS ■ G.SOAK (Guarantee soak) G.SOAK on/off state, type and G.SOAK width is set by the segment. G.SOAK are of three types: segment start point, segment end point and the entire segment. G.SOAK time is set using the variable parameter PA46 setting. Any offset between SP and PV triggers a G.SOAK wait which narrows the distance between SP and PV to guarantee the segment execution time.

  • Page 70: Pv Shift

    Chapter 5. FUNCTIONS • G.SOAK at end of segment PV and SP are compared at the end of the segment. The operation in that segment ends when the absolute value continues beyond the G.SOAK time and becomes narrower than G.SOAK width. A G.SOAK wait state continues until these conditions are met which is announced by the flashing of the linear LED at the center of the profile display.

  • Page 71: Repeat

    Chapter 5. FUNCTIONS ■ Repeat Repeat on/off and return destination are set by the segment with the segment number and repeat count. Operation completes at the end of a segment. If there is a repeat setting, the program returns to the start of the set destination segment and operation is resumed from there.

  • Page 72: Pv Start

    Chapter 5. FUNCTIONS ■ PV start When a PV start is set in the program setting, a PV start is performed in a normal RUN operation. The program looks for the first point where PV and the program pattern SP are equal (both PV and SP include bias) and starts operation from there.

  • Page 73: Cycle

    Chapter 5. FUNCTIONS ■ Cycle The cycle function allows you to repeat operation from segment 1 to the last segment in a program pattern the number of times set in the cycle count. A total of 10,000 times can be set. When a cycle number of n is set, the total operation count is n + 1.

  • Page 74: Pattern Link

    Chapter 5. FUNCTIONS ■ Pattern link The pattern link function links patterns; the program number of the link at the destination is set in the pattern link item. An initial value of 0 indicates that linking is not performed. When the number of the program is set in the pattern link item, it forms an eternal loop.

  • Page 75: Tag

    Chapter 5. FUNCTIONS ■ Tag Tags are 8-character alphanumerics, katakana or symbols that can be entered in a program. When segment 1 pattern item is set in a program setting, a total of eight characters consisting of PROG plus two characters in the program number and “__” two space characters.

In the program RUN mode, program operation progresses according as time elapses. Note, however, that G.SOAK (guarantee soak) wait, like the HOLD mode, halts program operation.
