Data Type
attributes to USINT or SINT, which have a 1-byte
Data Size
.
Width
– Required for SINT, INT, USINT, UINT, REAL
Data Types
. Defines the number of
ASCII bytes (1-16) that will represent the integer or real number.
Precision
– Required for REAL
Data Type
. Defines the number of digits (0 to 6) after the real
number decimal point. Gateway adds trailing zeros to the converted value if needed.

When bit 0 = 0, the ASCII bytes represent the
Transmit Data
integer number in a decimal
format. When bit 0 = 1, the ASCII bytes represent the integer number in a hexadecimal format.
This bit only applies to SINT, INT, USINT, and UINT Data Types.
When bit 7 = 1, leading zeros are added to real and integer numbers as needed to match the
Width
setting. This bit only applies to SINT, INT, USINT, UINT, and REAL Data Types.
Data in I/O Command
– Enables the Instance to use output data from the I/O Command
Message as its
Transmit Data
value. This bit must be set to enable the
Serial Transmit Object
Instance. All unused instances must be disabled.
