Ports Tab
Each communication port has its own parameters. Depending on the hardware, first ports in line are always physical serial ports and following them are TCP/IP ports using physical Ethernet ports. Number of ethernet ports also depends on hardware.
One communication port can be used by many devices, selection which port is used by each device is done in devices tab card, under device port selection.
Protocol: Communication protocol used by all the devices that toconfigured this port. Each protocol name is accompanied with a symbol ”^” or ”v” which indicates whether the port is used for an uplink or a downlink channel. For example, “Modbus v ” means that this port is used for downlink with Modbus protocol.
Baud rate: Data communication rate
Parity: Use of parity bit for all the devices on this channel
Stop Bit: possible values are 1, 2
Data Bits: possible values are 7, 8
Modem Settings: GPRS modem connection check period (if GPRS modem is chosen as protocol)
Communication Mode: Makes it possible to choose between the following handshaking options:
| 1 - No control |
| 2 - TCP/IP Legacy |
| 3 - TCP/IP Client |
| 0 - TCP/IP Server |
IP address: communication IP address (used if Communication Mode is set to TCP/IP)
- IEC ^ or IEC v
- Taandrida
- Taandrida
- Taandrida
Other’s side IP Address: an address of the device which can connect with Telem device using corresponding port e.g. SCADA server (if set to 0.0.0.0 – all devices can connect) Interface: Choose which Ethernet interface ise used in current port Port: Available network communication port (in case of IEC 60870-5-104 protocol, port 2404 is recommended) 61850 v IED IP Address: an IP address of the 61850 device (server) 102 – (RFC 1006) IEC 61850 port of ISO Transport on top of TCP Interface: Choose which Ethernet interface ise used in current port Provider Port:TCP port of IEC 61850 provider, port 7001 is recommended, in each network segment different port number has to be used GPRS settings: for GPRS modem ID detection from TDC/IEC software
Polling(v)/Answering(^) Delay [ms]: Delay between reception and the next query Port Link Address/Transp.con.Group: Link address of the device on uplink channels Length of Link Address: Length of the link address in bytes on uplink channels. Possible values are 1 or 2 IEC Port ASDU Address: ASDU address on uplink channels Length of ASDU Address: Length of the ASDU address in bytes on uplink channels. Typically 2, possible values are 1 or 2 IEC Object Length: Length of the IEC object address in bytes on uplink channels. Typically 3, possible values are 1, 2 and 3 Up Protocol SubVersion:Number of protocol subversion on uplink channels Query Timeout [ms]: Query timeout for devices on downlink channels Failed Query Count for disabling contr.: Count of timeouts after which the error flag is raised and the query of this device temporarily suspended Retry Query/Test Interval [s]: Time period after which the suspended device is queried again Suppress Echo: If the sent messages are echoed back by the connected devices then they need to be suppressed Replace Event hrs: Yes/No. If Yes, events are sent to control centre with UCT time (the time correction value is set in Common Menu, Timing Settings) Time: Determines the time tag of events Allow Timesync:Yes or No Control takeover DO obj.addr.: The address of an object that determines control takeover of that device Control takeover DI obj.addr.:The address of an object that shows which channel has taken over the control rights Time Zone: Determines time zone, localtime or Tallinn, Estonia, or UTC Comment: useful field for comments of port property
