C-40 1734 POINT I/O Module/RSLogix 5000 Controller Tag Reference
Transmit Record Number/ Receive Record Number / Length_Lo
Note that 7 data bits allows Transmit / Receive record Number of Length_Lo values of 0 to 127, which RSLogix 5000 software does support in the signed Short Integer data type SINT
Note that 8 data bits allows Transmit / Receive record Number of Length_Lo values of 0 to 255.
To enter values from +128 to +255, use this conversion formula:
Desired Decimal Value - 256 = Entered Decimal Value.
As an example, for a Transmit / Receive record Number of Length_Lo value of 128, 128 - 256 =
