Special data type conversion
When the data type is configured to "ASCII" in the sending message setting, [DATE-A], [DATE-Q], [TIME16], [TIME14],
[TIME12], and/or conversion table (when defined) options will be available.
The [DATE-A] and [DATE-Q] are used when the item data is ASCII time data.
For reception data, ASCII time data is converted to numerical time data and registered to a specified register. For sending
data, the register is referenced, and then the data is converted to ASCII time data and sent.
For details of data type conversion, refer to the following:
Page 281 Data Type Conversion
[TIME16], [TIME14], and [TIME12] are used to configure and send the calendar data held by the SECS/GEM communication
software pre-installed model module to the item data.
• [TIME16]: 16-byte format (YYYYMMDDhhmmsscc)
• [TIME14]: 14-byte format (YYYYMMDDhhmmss)
• [TIME12]: 12-byte format (YYMMDDhhmmss)
If conversion of these data types was specified by the reception frame, the time of the SECS/GEM communication software
pre-installed model module is overwritten. It is not registered to a register.
