Communication Interfaces
CESAR 1312 (E)
Dressler
®
HF-Technik GmbH
Bytes 0 and 1 of the upload packet contain information about the CESAR
generator; this information appears as status bits (or status “flags”).
defines these status bits:
In the first status byte, bit 13 (the active toggle bit) indicates the status of the
PROFIBUS
interface. After the CESAR generator has powered up, this bit’s
continuous change indicates that the
PROFIBUS
interface is ready. During
operation, a cessation of this change indicates that a communication problem
exists.
In the packet, bytes 8, 9, 10, 11, and 12 comprise the “data field” and contain
information defined by byte 13, the data field definition byte. Note that when
the data extends over more than one byte, the
PROFIBUS
sends the least
significant byte (LSB) before the most significant byte (MSB). Byte 13
references the requesting command.
Host Port—Ethernet (Modbus/TCP)
This section describes the
Ethernet
host port. For information on the
