CG4 369 MOTOR MANAGEMENT RELAY – COMMUNICATIONS GUIDE
PROFIBUS-DP COMMUNICATIONS CGCOMMUNICATIONS GUIDE
These settings can also be configured via the keypad under the S1 369 SETUP ØØØ 369
COMMUNICATIONS
path.
Physical Connection:
The 369 can be connected to an Ethernet LAN via the RJ45 connector at the back of the
369.
2 Profibus-DP Communications
2.1 Profibus Communication Options
The 369 Motor Management Relay supports either Profibus-DP (order code P) or Profibus-
DPV1 (order code P1) communication interfaces as slave that can be read and written to/
from a Profibus-DP/V1 master. The Profibus-DP/V1 Master must read the GSD (Device
Master Data) file of the 369 for the purposes of configuration and parameterization.
• The GSD file for the Profibus-DP option is 369_090C.GSE.
• The GSD file for the Profibus-DPV1 option is 369_09E6.GSE.
Sections 2.2 to 2.4 pertain to the Profibus-DP option.
Sections 3.1 to 3.6 of this manual pertain to the Profibus-DPV1 option.
2.2 369 Relay Profibus-DP Parameterization
The 369 Motor Management Relay supports mandatory parametrization. The relay keeps
its user parameter data / setpoints in a non-volatile memory and does not need device
related parametrization during startup of the DP master. The EnerVista 369 Setup software
is the best tool for user parametrization of the 369 device.
2.3 369 Relay Profibus-DP Configuration
The Profibus-DP basic configuration has one DP master and one DP slave. In a typical bus
segment up to 32 stations can be connected (a repeater has to be used if more than 32
stations operate on a bus). The end nodes on a Profibus-DP network must be terminated to
avoid reflections on the bus line.
The bus address for the relay as Profibus-DP node can be set using the

for commissioning purposes and should not be used to exchange user data.
