Profibus Dp - Pilz PMCprimo C Operating Instructions Manual

Function description
CAN devices detected by the motion controller are ready for operation immediately
}
after the initial network run-up. No complex configuration of the CAN devices is re-
quired.
The overall cable length and the length of the stub lines depend on the transmission
}
rate.
Process data objects (PDO) are defined for each CAN device type and cannot be cus-
}
tomised by the user.
For servo amplifiers, the "FS" command can be used to set which process data is to be
}
exchanged between the motion controller and the servo amplifier (see "PMCprimo Pro-
gramming Manual").
The signal lines must be terminated with resistors (120 Ohm) on the first and last sub-
}
scriber. The resistors are generally integrated within the connected devices and can be
activated there. For a PMCprimo C, a terminating resistor can be activated in the field-
bus junction box PMCprotego D.CAN-CANbus Adapter or PMCprotego D.CAN-
PFOFIBUS Adapter.

PROFIBUS DP

PROFIBUS is an open fieldbus standard. Communication is defined in IEC 61158 and IEC
61784. Further provisions have been defined in specifications published by the PROFIBUS
User Group. These specifications are available from PROFIBUS International.
On a certain unit type, the PROFIBUS interface is available together with a CANopen inter-
face on an RJ45 socket (X42).
Properties:
The PROFIBUS is configured using the CD command: Slave address, address range,
}
see PMCprimo Programming Manual.
A total of up to 108 bus variables can be read and written (see PMCprimo Programming
}
Manual):
–
–
–
When changing the variable content, any programs can be started if the bus variables
}
have been defined as trigger variables.

Address space of bus variables: $B1 to $Bx108 (can be set using the CD com-
mand).
Data width: 16 Bit including sign
Value range: -32768 to 32767 (Hex: 0x0000 to 0x7FFF).
INFORMATION
The GSD file is available on the supplied CD-ROM. The name of the de-
scription file can be found in the "Technical Details".
