8.10.1.8 Micro-Serial Server
The CR6 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.
8.10.1.9 Modbus TCP/IP
The CR6 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. 525).
8.10.1.10 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 CR6 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. 660).
8.10.1.11 Ping (IP)
Ping can be used to verify that the IP address for the network device connected to
the CR6 is reachable. To use the Ping tool, open a command prompt on a
computer connected to the network and type in:
ping xxx.xxx.xxx.xxx <Enter>
where xxx.xxx.xxx.xxx is the IP address of the network device connected to the
CR6.
8.10.1.12 SNMP
Simple Network Management Protocol (SNMP) is a part of the IP suite used by
NTCIP and RWIS for monitoring road conditions. The CR6 supports SNMP
when a network device is attached.
