CH1 HART device information (message)
A message set to a HART-enabled device by users is stored. Sixteen words of the buffer memory areas are used per channel.
■Stored value
• The set message is converted to 32 characters of ASCII code (hexadecimal) and stored.
• The first character is stored in the lower byte (LSB) of the lowest address.
• A space (code: 20H) is assigned to the last character.
Ex.
When a message of a CH1 HART device is 1234
