8.10.1.7 Micro-Serial Server
The CR800 can be configured to allow serial communication over a TCP/IP port.
This is useful when communicating with a serial sensor over Ethernet with micro-
serial server (third-party serial to Ethernet interface) to which the serial sensor is
connected. See the network-link manual and the CRBasic Editor Help for the
TCPOpen() instruction for more information.
8.10.1.8 Modbus TCP/IP
The CR800 can perform Modbus communication over TCP/IP using the Modbus
TCP/IP interface. To set up Modbus TCP/IP, specify port 502 as the ComPort in
the ModBusMaster() and ModBusSlave() instructions. See the CRBasic Editor
Help for more information. See Modbus — Details
(p. 436).
8.10.1.9 PakBus Over TCP/IP and Callback
Once the hardware has been configured, basic PakBus communication over
TCP/IP is possible. These functions include the following:
• Sending programs
• Retrieving programs
• Setting the CR800 clock
• Collecting data
• Displaying the current record in a data table
Data callback and datalogger-to-datalogger communications are also possible over
TCP/IP. For details and example programs for callback and datalogger-to-
datalogger communications, see the network-link manual. A listing of network-
link model numbers is found in Network Links — List
(p. 570).
