The
Data Size
attributes for all 8
Serial Receive Object
instances must sum to a total less than or
equal to 128 bytes, regardless of whether an instance is enabled or not. Set unused instances’
Data Type
attributes to USINT or SINT, which have 1-byte
Data Size
.
Width
– Required for SINT, INT, USINT, UINT, REAL
Data Types
. Defines the number of
ASCII bytes (1-16) to be converted into an integer or real number.
Conversion
– Required for SINT, INT, USINT, UINT
Data Types
. Denotes if the ASCII bytes
represent a decimal integer (‘D’ or 0x44) or a hexadecimal integer (‘X’ or 0x58).
Pad Char
– Byte value to pad the RX Message bytes.
Data in I/O Response
– Enables the Instance to send its
Receive Data
value as input data in the
I/O Response Message. Typically you would always have this attribute enabled when the
Instance is enabled. For more complex applications, the Instance’s
Receive Data
can be read
using the Get_Attribute command (explicit message), reducing the number of input bytes in the
I/O Response Message. All disabled Instances must have this attribute set to zero.
Enabled
– Enables the
Serial Receive Object
instance. When enabled, the Instance processes
received messages based on its
Receive Mode
and
Data Type
. This attribute must be disabled for
all unused
Serial Receive Object
Instances.
Sync Enabled
– Enables receive synchronization with the user application. When enabled, the
instance will not update its
Receive Data
until the
Receive Acknowledge
bit matches the
Receive
Toggle
bit. Enabling receive synchronization ensures that the user application does not miss any
received message data between polls.
