4.3.5 Node Address
PID283 - Node Address
Default: 126
Access: RW
Set PID283 to the required value. The default address is 126. The permissible address range is: 0 – 125.
Each node on the network must have an individual address, if two of more nodes have duplicate addresses
this may prevent the network from functioning correctly. Node 126 is a special node address intended for
"New" nodes only where by node configuration is performed via a network master device.
4.3.6 Baud / Data Rate
The PositionServo PROFIBUS-DP module automatically detects and synchronises to the data rate of the
network to which it has been connected.
4.3.7 Data Mapping
• The PositionServo PROFIBUS-DP module has support for up to 12 cyclic data channels in both
directions.
• Cyclic data configuration is described in full in section 5.
• The default mapping for PositionServo PROFIBUS-DP is 4 Data IN links and 2 Data OUT links, the
configuration is shown in Table 4.
Data OUT Link
1
2
NOTE
• The data size of each IN and OUT Link / Channel is 4 Bytes per link.
• The terms "OUT data" and "IN data" describe the direction of data transfer as seen by the PROFIBUS-
DP network master controller.
