Page 51

■Operation [Operation performed when an alarm is output] Digital output values are monitored on the rate alarm alert detection cycle. When a change rate of a digital output value (from a previous value) is equal to or more than the rate alarm upper limit value, or the rate is equal to or less than the rate alarm lower limit value, an alert is output as follows.
Page 52

■Judgment of rate alarm The rate alarm is judged as follows according to the setting of 'Rate alarm change rate selection' (Un\G299). • When 'Rate alarm change rate selection' is "Rate specification" The change rate is judged with 'CH1 Rate alarm upper limit value' (Un\G524) and 'CH1 Rate alarm lower limit value' (Un\G526) converted to digital values per rate alarm detection cycle.

Set "Input signal error auto-clear enable/disable setting" to "Enable" or "Disable". Setting example ■Setting example of the input signal error detection In the channel where the following values are set, an input error is detected when an analog input value falls below -10.2 V or exceeds +10.2 V.
Page 61: Logging Function

Logging function This function stores 10000 points of digital output values or digital operation values per channel in the buffer memory area. In addition, the data collection can be stopped by using the status change of the data as a trigger. This function also helps the error analysis since the data before and after the occurrence of an error is held.
Page 62

Operation of logging ■Starting logging data collection Logging data collection starts when 'CH1 Logging enable/disable setting' (Un\G535) is set to Enable (0) and 'Operating condition setting request' (Un\G70, b9) is turned offonoff. The data in 'CH1 Digital output value' (Un\G400) or 'CH1 Digital operation value' (Un\G402) is stored in CH1 Logging data (Un\G10000 to Un\G19999) on the set logging cycle.
Page 63

Logging cycle ■Logging cycle setting Set the logging cycle with 'CH1 Logging cycle setting value' (Un\G537) and 'CH1 Logging cycle unit setting' (Un\G538). The following table lists the setting range for each cycle. Setting value of CH1 Logging cycle unit setting Setting range of CH1 Logging cycle setting value s (0) 80 to 32767...
Page 64

When 'Operating condition setting request' (Un\G70, b9) is turned offonoff on the condition that the logging cycle determined by 'CH1 Logging cycle setting value' (Un\G537) and 'CH1 Logging cycle unit setting' (Un\G538) is shorter than the conversion cycle, an error occurs and logging does not start. A logging cycle setting disable error (error code: 1D2H) is stored in 'Latest error code' (Un\G0), 'Error flag' (Un\G69, b15) and the ERROR LED turn on.
Page 65

■Checking logging data without stopping the logging operation Logging data can be checked during the logging operation with 'CH1 Head pointer' (Un\G434), 'CH1 Latest pointer' (Un\G435), and 'CH1 Number of logging data' (Un\G436). To check logging data during logging operation, follow the precautions below because logging data may be refreshed while data is being read out.
Page 66

Stopping the Logging Operation Logging operation stops (holds) when the preset trigger condition is satisfied and the set points of the data are collected. A trigger that is generated when the condition is satisfied is called a hold trigger. To generate a hold trigger, the following two methods are available. Page 67 Logging hold request Page 68 Level trigger When a hold trigger is detected during data collection, the logging operation stops after the points of the data set in 'CH1 Post-...
Page 67

• Checking the trigger generation time The trigger generation time can be checked with 'CH1 Trigger generation time' (Un\G444 to Un\G448). Even when the logging cycle is set to a period less than 1 millisecond (Example: 80 s), the minimum time unit recorded in 'CH1 Trigger generation time' (Un\G444 to Un\G448) is millisecond.
Page 68

■Resuming the logging It may take time until ON (1) is stored in 'CH1 Logging hold flag' (Un\G409) after 'CH1 Logging hold request' (Un\G471) is changed offon. To resume logging, check that ON (1) is stored in 'CH1 Logging hold flag' (Un\G409) and 'CH1 Logging hold request' (Un\G471) is changed from onoff.
Page 69

Logging hold request A hold trigger is generated from a program at any timing. Logging starts when ON (1) is set to 'CH1 Logging hold request' (Un\G471) and stops after a preset number of the data is collected. Controlled by the analog input module 'CH1 Logging hold request' OFF(0) ON(1)
Page 70

Level trigger When a value in the monitored buffer memory area of an analog input module satisfies a preset condition, a hold trigger is generated. A level trigger is monitored on the refreshing cycle of the digital output value or the digital operation value. ■Initial setting of a level trigger [Setting a target to be monitored] As a condition to generate a hold trigger, set the buffer memory address to be monitored to 'CH1 Trigger data' (Un\G541).
Page 71

• Set a value where a hold trigger is generated to 'CH1 Trigger setting value' (Un\G542). Item Setting range CH1 Trigger setting value (Un\G542) -32768 to +32767 The following figure shows the relation between setting items to be configured for the initial setting of a level trigger.
Page 72

■Operation of a level trigger To use a level trigger, set ON (1) to 'CH1 Logging hold request' (Un\G471) in advance. At the point where ON (1) has been set to 'CH1 Logging hold request' (Un\G471), the module becomes the trigger condition wait status. After the trigger condition has been satisfied, and the set points of the data have been collected from that point, the logging stops.

Executing the wave output function This section describes the procedure for executing the wave output function. After the initial setting of the wave output function, execute the contents of this section. ■Transfer the wave output data The CPU module power is turned offon or reset, and the wave output data created with module extension parameter "Wave output data creation tool"...
Page 215

■Changing the module settings For the wave output function parameter settings written with the program, 'Operating condition setting request' (Un\G70, b9) needs to be turned offonoff to enable the settings. When the settings are enabled, the CH1 Analog output value set as D/ A conversion enable changes to the following depending on the status of the 'CH1 Output enable/disable flag' (Un\G70, b1).
Page 216

■Start, stop, or pause the wave output [Starting the wave output] After the wave data is registered, the wave output can be started using the following procedure. Turn on 'CH1 Output enable/disable flag' (Un\G70, b1). Turning on this flag outputs the 'CH1 Output setting during wave output stop' (Un\G524) setting as analog data. Set 'CH1 Wave output start/stop request' (Un\G462) to Wave output start request (1).
Page 217

[Pausing the wave output] • To pause the wave output, set 'CH1 Wave output start/stop request' (Un\G462) to Wave output pause request (2). The wave output pauses by changing from Wave output start request (1) to Wave output pause stop request (2). In addition, Wave output paused (2) is stored in 'CH1 Wave output status monitor' (Un\G401).

The wave output update continues also while ‘CH1 Output enable/disable flag’...
Page 221

■If the CPU module status was changed during output When the CPU module status was changed during wave output, after terminating the wave output, it operates as follows depending on the analog output HOLD/CLEAR function setting. • For the previous value If the CPU changes from RUN to STOP, the wave output terminates and the value immediately before STOP is held.
Page 222

• For the setting value If the CPU changes from RUN to STOP, the wave output terminates and its value is held as the 'CH1 HOLD setting value' (Un\G596). When 'CH1 Output enable/disable flag' (Un\G70, b1) is turned on with the CPU module changed from STOP to RUN, the output changes as per the setting of 'CH1 Output setting during wave output stop' (Un\G524).
Page 223

• For CLEAR If the CPU changes from RUN to STOP, the wave output terminates and the offset value is output. When 'CH1 Output enable/ disable flag' (Un\G70, b1) is turned on with the CPU module changed from STOP to RUN, the output changes as per the setting of 'CH1 Output setting during wave output stop' (Un\G524).
Page 224

■When an error occurs If a value out of the setting range of the output range is attempted to be output, an error will occur and error code 191H is stored in ‘Latest error code' (Un\G0); 'Error flag' (Un\G69, b15) turns on at this time. If this error (error code: 191H) occurs during wave output, the analog output value will be as follows.
Page 225

■When the external power supply turns off during wave output When the external power supply turns onoff during without, the wave output status of every channel stops and the wave output fully stops. If the external power supply turns offon at this time, the wave output will not restart. To restart the wave output, after the external power supply turns offon, check that the status of the analog output module and the externally connected devices.
Page 226

■When the disconnection occurs during wave output When the disconnection is detected during wave output, the wave output status of the channel in which the disconnection was detected becomes the wave output stopping, and the wave output completely stops. Even if the disconnection cause is eliminated from the disconnection status, the wave output is not restarted.
Page 227

■Using the wave output function as PWM The wave output function is available also as PWM with the shortest pulse width of 80 s. In addition, since any number of pulses can be analog output by only creating a one pulse wave pattern, it contributes to reduction of man-hours for program creation.
