Note
You need to set device mode as Normal before using this function.
The contrast control function compares the data that the device reads with preset data and outputs
contrast result. The result can be used as the event source of trigger signal, including Contrast
Success and Contrast Fail. This function has two ways to contrast, including regular contrast and
consecutive number contrast.
Regular Contrast
The regular contrast requires you to set code contents in advance, and the client software will
contrast the data that the device reads with preset contents and outputs comparison result.
Steps
1. Right click the device in Device Connection, and click Feature Tree.
2. Go to Contrast Control, enable Contrast Enable, and select Regular as Contrast Rules.
3. Set Start Position that means the stating position of the comparison.
4. Set Character Number that means the comparison quantity.
5. Set code contents in Wildcard String.
Note
You can use wildcard * and ?. * stands for multiple strings you can use, and ? stands for one string
you can use. * can be used once only and ? can be used many times.
