If a DTM allows a Frame Appl
30、ication, other DTMs, or a controller the direct access to its process values via IEC 61784 CPF 6 protocol, it should provide FDT-Channel objects as described in this clause. Only the complete description of all channels belonging to an IEC 61784 CPF 6 process value allows proper access for external
31、applications. The description of channels, especially of the process values, allows the Frame Application to support the device in a more efficient way. The data types are used at GetChannelParameters service and SetChannelParameters services. The information returned by the GetChannelParameters ser

An IEC 61784 CPF 6 scan may detect different device types: IEC 61784 CPF 6 devices following the base profile, IEC 61784 CPF 6 PCP devices and simple IEC 61784 CPF 6 devices. The following rule shall be applied for IEC 61784 CPF 6 Communication Channels: if an
44、IEC 61784 CPF 6 base profile is available, create an IEC 61784 CPF 6 base profile identification; otherwise check IEC 61784 CPF 6 PCP; otherwise create a simple IEC 61784 CPF 6 device identification. 12.1 Protocol specific handling of data type STRING IEC 61784 CPF 6 char array rules In all strings
45、based on char ranges defined in the field bus protocol specification, the leading spaces are left trimmed. The char array is to be filled with 0x20h (blank). In VisibleStrings, invisible characters provided by a device have to be replaced by ?. Characters within VisibleStrings, which are not defined
46、 in the 7 bit ASCII/ANSI character set, are considered to be invisible. 12.2 Device type identification data types The IEC 61784 CPF 6 device type identification data types provide general data types with a protocol specific semantic (see Table 10, Table 11 and Table 12) as well as data types withou
47、t such a mapping (see Table 13). The data types described in this clause are defined for the following namespace.
