This tab allows for the creation of ethernet or serial communications settings. Communications settings are used to communicate with SCADASuite applications on an RTU. Separating the communications settings from application configurations makes it easy to apply the same configuration to multiple RTUs, or to apply different configurations to different RTUs that share a communications path.
Both ethernet and serial communications use a Modbus-like protocol with custom function codes. A target station address is required, messages contain binary data, and messages are limited to 256 bytes in length.
For ethernet communications, Modbus RTU in UDP, Modbus RTU in TCP and Modbus TCP protocols are supported. The configured station address and port number on the Comm Settings Tab must match the RTU's communication settings.
Serial communications are not packetized and bytes are simply transmitted and received from a local serial port. The station address and baud rate should match the station address on the serial port of the RTU that you are attempting to communicate with. Other serial settings are fixed at 8-N-1 (8 data bits, 1 stop bit, no parity.)
Use the insert key to create new settings. Use the delete key to delete settings.
Comm Settings Tab
Ethernet settings
Use this area to create, delete and edit ethernet communications settings. Use the insert key to create new settings, and the delete key to delete settings.
Name. A user configurable name for the settings.
IP Address. The target IP address in IPV4 format. DNS lookup and IPV6 are not supported.
Connection Type. Choose the communications protocol.
Local Port. The local port on which to send communications from. Leave this at 0 to allow Windows to select a port. This is the recommended setting.
Remote Port. The port that the RTU is expecting to receive messages on. This value must match the UDP Port Number setting on the Modbus RTU in UDP settings on the RTU. 49152 is the default in both the PC Configuration Program and in Telepace Studio.
Station Address. The Modbus station address of the target RTU for the Modbus RTU in UDP protocol.
Use this area to create, delete and edit serial communications settings. Use the insert key to create new settings, and the delete key to delete settings. Serial communications settings always use 8 data bits, 1 stop bit and no parity (8-N-1).
Name. A user configurable name for the settings.
Com Port. The local serial port to use to communicate.
Baud Rate. The setting here must match the setting of the serial port on the RTU.
Station Address. The Modbus station address of the serial port on the target RTU.
