5. unit count for the LTX controller Typically this is to a limit of 16 units but some new LTX controllers may be able to address up to 64 units If it is necessary to use more than one interface then each interface is bound to successive VCI Proxies For example a second LTX interface would be bound to VCI Proxy 1 this performs a default mapping so that unit 1 in the second LTX corresponds to unit number 17 in the VCI and unit 16 in the second LTX corresponds to unit number 32 in the VCI Each of the proxy function blocks has two configuration parameters UCPTStartUnitOffset and UCPTEndUnitOffset which can be used to map each proxy to any address range within the range 1 to 64 If the configuration parameters are set to zero the function block will operate with default address ranges outline above These offset values can be used to map units into the correct address range should a site addressing scheme not begin at 1 1 3 3 Fault Code Mapping Existing LTX controllers use an established fault reporting system that allows fault codes to be translated and reported in various different BMS architectures To retain backwards compatibility the current version of the VCI translates manufacturers fault codes into the established fault code format In the BMS the LTX can be translated back into the native manufacturers codes either manually or using suitable lookup mechanisms Each Device Interface Sheet provides the necessary translation between LTX and m
