Ex.
Condition specification: M0=ON
■Condition specification
Configure the trigger condition based on the device data value. A trigger occurs when the monitored data meets the specified
condition.
• : When the specified data turns off and on
• : When the specified data turns on and off
• =: When the monitored data is equal to the comparison value, regardless of whether or not its current value is equal
• : When the monitored data is not equal to the comparison value, regardless of whether or not its current value is equal
• : When the monitored data is greater than or equal to the comparison value, regardless of whether or not its current value
is equal
• >: When the monitored data is greater than the comparison value, regardless of whether or not its current value is equal
• : When the monitored data is less than or equal to the comparison value, regardless of whether or not its current value is
equal
• <: When the monitored data is less than the comparison value, regardless of whether or not its current value is equal
• At change: When the current value of the specified data changes
■Specifying the monitored data
For the device change specification, monitored data can be specified from the devices listed in the following table. The data
types that can be selected include bit/word (unsigned), word (signed), double word (unsigned), and double word (signed). If
double word (unsigned) or double word (signed) is specified, a trigger occurs only when data equal to one double word is
written. No trigger occurs when only the upper or lower word of a double word is written.
*1 Index modification, and indirect specification cannot be specified.
*2 For bit devices, bit specification of word cannot be specified.
*3 For word devices, nibble specification of bit devices cannot be specified.
*4 To specify these devices with the CPU Module Logging Configuration Tool, use T (contact): TS, ST (contact): STS, C (contact): CS, LC
(contact): LCS.
*5 To specify these devices with the CPU Module Logging Configuration Tool, use T (current value): T or TN, ST (current value): ST or
STN, C (current value): C or CN, and LC (current value): LC or LCN.
*6 This format is supported by the FX5UJ and FX5U/FX5UC CPU modules.
