Chapter 9 Communication
CSP Addressing
This type of addressing is also known as ‘PLC-5 style’ or ‘PCCC’ addressing.
Addresses are written in the form ‘Axx:yy’ where A is a letter describing the
function of the data table, xx is the table number, and yy is the element within, or
offset into, the table. For example, ‘F53:0’ is the CSP address of the first element
in the MeteringResults.RealTime_VIF_Power
table on on page 373. PCCC
messaging can be used to read or write a single data element or a range of data
elements within a data table.
Data Types
The PowerMonitor 5000 unit stores data by using several data types:
• Int16, in which the 16-bit word can be represented by an integer value or a
bitmap
• Int32, a 32-bit integer value
• SINT, an 8-bit (Byte) value
• REAL, using the 32-bit IEEE 754 floating-point format
• String, containing alphanumeric characters used for security and unit
descriptive information
• DWORD, a 32-bit structure typically containing bitmap status
information
• SINT, INT, and DINT data types are also used as pads for data alignment
with the Logix architecture
