Transmit Record Number/ Receive Record Number / Length_Lo Note:
Note that “7 data bits” allows Transmit / Receive record Number of
Length_Lo values of 0 - 127, which RSLogix 5000 does support in the signed
Short Integer data type SINT (-128 to +127 range).
Note that “8 data bits” allows Transmit / Receive record Number of
Length_Lo values of 0 - 255.
To enter values from +128 to +255, use this conversion formula:
Desired Decimal Value - 256 = Entered Decimal Value.
Example: For a Transmit / Receive record Number of Length_Lo value
of 128, 128 - 256 = -128
