parameter channel
process data channel
cyclic data channel:
P-0-04071, Field bus: length of cyclic command value data ch.
P-0-04082, Field bus: length of cyclic actual value data channel
Fig. 4-21: Structure of cyclic data channel
Note:
To simplify field bus communication Bosch Rexroth makes
available function blocks for different programmable logic
controllers (PLCs). The principles applied to the function
blocks can be easily used for other field bus masters.
The slave PROFIBUS-DP circuit with master communication module PL
has the following functional features:
•
support of RS485 interfaces according to
IEC61158-2
•
support
of
all
data rates
according to
IEC61158-2
, with exclusive use
of PROFIBUS-DP (9.6 kBaud, 19.2 kBaud, 45.45 kBaud, 93.75 kBaud,
187.5 kBaud, 500 kBaud, 1.5 MBaud, 3 MBaud, 6 MBaud, 12 Mbaud)
•
automatic baud rate detection
•
configurable
cyclical data
up to 8 parameters (incl. field bus control
word and field bus status word) in both data directions
(
→
max. 30 bytes or 15 words)
•
additional
optional
parameter channel
in the cyclic channel with up to
16 byte (8 words)
•
monitoring of the cyclical data exchange (watchdog function)
•
LED for diagnosing the PROFIBUS interface
•
supported DPV0 services:
•
Slave_Diag (read diagnostic data)
•
Get_Cfg (read configuration data)
•
Set_Prm (send parameterization data)
•
Chk_Cfg (check configuration data)
•
Data Exchange (transfer I/O data)
•
Global Control (synchronization)
•
RD_Outp (read output data)
•
RD_Inp (read input data)
•
parameter access with DPV1-class-1 services
•
DDLM_Initiate (establishment of connection)
•
DDLM_Read (acyclic read access)
•
DDLM_Write (acyclic write access)
•
DDLM_Abort (connection clearance)
•
DDLM_Idle (connection monitoring)
•
support of up to five DPC1-class-2 connections
•
supported field bus profiles:
•
0xFF82: I/O mode with configurable real-time data
•
0xFFFE: freely configurable mode
