1. | What SNMP protocols are implemented in SAEAUT SNMP OPC Server?
|
· | SNMPv2c.
|
· | SNMPv1.
|
2. | What OPC interfaces are implemented in SAEAUT SNMP OPC Server?
|
· | OPC Data Access 3.0, 2.05 and 1.0.
|
· | OPC Alarm and Events 1.0.

3. | The first start of SAEAUT SNMP OPC Server.
|
4. | The first start of SAEAUT SNMP OPC Server passed successfully, but Quality of items is "Bad" and the item Subquality is "Comm Failure".
|
5. | Writing the value on data item doesn't work. Why?
|
· | Data item is read only: Check the rights of data items you are using. Open SAEAUT SNMP Server Configurator and choose data item. Change the rights to Read/Write.
|
· | Community of the device is read only: Check the rights of the community you are using. When the device is PC, in administrative tools choose services and SNMP service. Open SNMP service Properties dialog and choose Security tab. Check Accepted community names and choose the community you are using. Change the rights to READ WRITE. You can add your own communities with desired rights and use them when configuring the device.
|
6. | Which communication ports does the SAEAUT SNMP OPC Server exploit?
|
· | SNMP (UDP 161)
|
· | SNMP Trap (UDP 162)
|
OPC communication (between SNMP OPC Server and OPC Client):
· | OPC (TCP 135)
|
XML-DA communication (between SNMP OPC Server and XML-DA Client):
· | XML-DA (HTTP/SOAP 80)
|
Heartbeat communication (between SNMP OPC Server and SNMP device):
· | Heartbeat (ICMP Echo (ping) request; ICMP Echo (ping) reply). ICMP is Internet Control Message Protocol.
|
Be aware that according to required communication is necessary to permit a port in your firewalls. Settings of the standard operating system firewall are made automatic during installation.
