Using TagTextSerial to display serial numbers from PLCs

This allows a set of tags to point to a string area in a PLC which is used to hold string text � this can then be read in and displayed by a digital object, or saved to a custom report.

Tag Text Serial data setup

1. The strings are held in the PLC, two ascii characters per word.

Such as DM 100, each two characters requires 1 tag, thus a 16 char string would need 8 tags.

2. A set of tags is setup to read the entire length of the string (for 16 char string as above)

Tag 1=DM 100
Tag 2=DM 101
Tag 3=DM 102
Tag 4=DM 103
Tag 5=DM 104
Tag 6=DM 105
Tag 7=DM 106
Tag 8=DM 107

To display on a Mimic Screen, use a digital object, set the Type to Tag Text Serial
