Translation ChallengesData ResolutionTHE CHALLENGE‣ <strong>LonWorks</strong>‣ Supports data types from 8-bit 8through to 64-bit <strong>and</strong> allowsfor corresponding resolutions in the different SNVT’s‣ <strong>LonWorks</strong> has two common SNVT’s s to manage binary datatransfer: SNVT_switch <strong>and</strong> SNVT_state. . Both are 16-bitSNVT’s.SNVT_switch is more popular.‣ <strong>Modbus</strong>‣ Supports two basic data types: 1-bit 1<strong>and</strong> 16-bit.‣ All <strong>Modbus</strong> variations that support 32-bit are applicationlayer enhancements that combine two registers at the lowerlevel‣ The challenge is matching the different resolutions in thetwo protocols to achieve the desired resolution for theapplication.
