Data Type 16 This parameter (/swap16) is used only in conjunction with points of data type 16 (see section ). String This parameter (/swapstring) is used only in conjunction with points of string data types (see section ). TCP/IP Header Since some Modbus TCP/IP systems may not support the standard Modbus Application Protocol (MBAP) header, an optional parameter (/hcp) is provided so that the message packets do not use the standard header (see for more details): Node Trace The trace group of buttons and fields gives the user the ability to turn on and off debug tracing for particular actions and data in the interface for the selected Ethernet node. In general, tracing need only be turned on when instructed by OSIsoft technical support personnel. Tracing is described in more detail in the section (/debug=#). Requests Trace the Modbus request buffers. Responses Trace the Modbus response buffers. Scan Lists Trace the scan list processing control. Tag Groups Trace the tag groups that represent a group of tags to request. Device Points Trace the device points that represent a tag in the interface. Tags Trace the tags (i.e. PI points) in the interface. Communications Trace the general flow of communications such as opening, closing and reconnecting Ethernet nodes.
