CG2 369 MOTOR MANAGEMENT RELAY – COMMUNICATIONS GUIDE
OVERVIEW CGCOMMUNICATIONS GUIDE
1.2 Profibus Communications
The 369 Motor Management Relay supports both Profibus-DP (order code P) and 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.
• The relay supports the following configurations and indications:
• Fieldbus type: PROFIBUS-DP (IEC 61158 Type 3, and IEC 61784)
• Auto baud rate detection 9.6Kbit - 12Mbit.
• Address range: 1-126, setting via EnerVista 369 Setup software or front
keypad.
• Input data: 220 bytes - cyclical.
• Extended Diagnostic data: 26 bytes - non-cyclical.
• Sections 2.2 to 2.4 pertain to the Profibus-DP option.
• In addition to the above, the Profibus-DPV1 (P1) option supports:
• Fieldbus type: Profibus-DPV1 (IEC 61158 Type 3, and IEC 61784)
• Acyclic read/write between a Master (Class1/Class2) and the 369 slave
according to the DPV1 extensions of IEC 61158.
• Output Data: 2 bytes - cyclical.
Sections 3.1 to 3.6 of this manual pertain to the Profibus-DPV1 option.
1.3 DeviceNet Communications
The 369 Motor Management Relay supports the optional DeviceNet protocol as slave that
can be read by a DeviceNet master. The device can be added to a DeviceNet list by adding
the 369.eds file in the scanner list. The EDS file can be generated using the EnerVista 369
Setup program.
The relay supports following configuration.
• Field bus type: DeviceNet
• Functions supported: Explicit, Polled, COS and Cyclic IO messaging
• Baud Rate: 125, 250 and 500 kbps, programmable through software or relay front
keypad
• Mac ID: 0 to 63, programmable through software or relay front keypad
See section 4: DeviceNet Protocol, for complete details.
1.4 Modbus Communications
The 369 implements a subset of the AEG Modicon Modbus RTU serial communication
standard. Many popular programmable controllers support this protocol directly with a
suitable interface card allowing direct connection of relays. Although the Modbus protocol
is hardware independent, the 369 interfaces include three 2-wire RS485 ports and one
