PROFIBUS CONNECTOR AND PIN DESCRIPTIONS
Table 4-4 provides descriptions for the PROFIBUS port pins.
PROFIBUS PROTOCOL
PROFIBUS (Process Field Bus) is an interface that lets you communicate with
the HPG generator from a host (master). Dressler manufactures a certified
PROFIBUS, which means the interface is tested and certified to work with
PROFIBUS masters described in the DIN 19245 PROFIBUS Standard DP,
part III. Any PROFIBUS master that complies with this standard can
communicate with Dressler's certified PROFIBUS.
The PROFIBUS connection on the HPG generator is a 9-pin, female,
subminiature-D connector on the rear panel. The following sections describe
the
PROFIBUS protocol. Please note that Dressler's PROFIBUS protocol
does not support the following functions: address changing, freeze/unfreeze
modes, or sync modes.
PROFIBUS Type Files (GSD Files)
Type files are computer files that some Programmable Logic Controllers
(PLCs) use to compile PROFIBUS programs. These files are device-specific
and contain information on features found in that device. Thus, a different type
file should be defined for each PROFIBUS device.
For older Siemens
®
PROFIBUS PLCs, the type file is proprietary to Siemens
Energy & Automation
®
(SE&A
®
); hence, SE&A must create the type file.
Newer PROFIBUS PLCs use a non-proprietary equivalent of a “type file,”
generally referred to as a “GSD file.”
