7 FREQUENTLY ASKED QUESTIONS 7.1COMMUNICATIONS
Q1.
Does the G650 support DNP and ModBus over the Ethernet port?
A1.
G650 units support both protocols over both the asynchronous serial ports and the Ethernet LAN synchronous port
using TCP/IP and UDP/IP layers over the Ethernet.
Q2.
Does this equipment support dual IP access?
A2.
Yes, it supports two independent IP addresses in aliasing mode. Those address go in the communications settings
Network0 and Network1.
Q3.
Is the protocol IEC 870-103 supported by the G650?
A3.
At this moment it is not supported.
Q4.
Can the G650 be used as a DNP master station?
A4.
Not at this moment. It works as a slave IED station for all protocols.
Q5.
How many communication ports are included in the G650?
A5.
The equipment has 2 different boards, one for asynchronous serial ports and another for a high-speed synchronous
Ethernet port. The first board has 2 comm ports, COM1 and COM2. COM2 is multiplexed with the front serial RS232
port, whereas the COM1 port is completely independent from COM2.
The synchronous LAN port is COM3.
Q6.
Are there one or two Ethernet ports?
A6.
The equipment has only 1 Ethernet port. For redundant fiber optic versions, redundancy is done at the physical level
(fiber optic) but there is just one port.
Q7.
How many different communication Ethernet sessions can be opened through the LAN port?
A7.
ModBus TCP/IP:4 sockets
DNP TCP/IP:3 sessions
Q8.
May I use the cooper 10/100 BaseTX connection included in the basic model with all protocols?
A8.
Yes, it may be used with all protocols. In noisy substation environments and/or long distances, it is recommended to
use fiber optic options due to much better EMC performance and immunity. For fiber optic models, it is necessary to
adjust an internal jumper to use the copper port.
Q9.
Remote I/O CAN bus. Does it support DeviceNet protocol?
A9.
No it does not support DeviceNet.
Q10. Which functions are available in the relay web server?
A10. Currently, it includes several functions for viewing measures and retrieving information.
Q11. Q11 May I use URPC to program the relay?
A11. Only oscillography records may be viewed with URPC once downloaded to a file using the ENERVISTA 650 Setup
software.
