8.6.3.8 Ping (IP)
Ping can be used to verify that the IP address for the network device connected to
the CR1000 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
CR1000.
8.6.3.9 Micro-Serial Server
The CR1000 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. Information on available network
links is available in the appendix Network Links
(p. 652).
8.6.3.10 Modbus TCP/IP
The CR1000 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
(p. 411).
8.6.3.11 DHCP
When connected to a server with a list of IP addresses available for assignment,
the CR1000 will automatically request and obtain an IP address through the
Dynamic Host Configuration Protocol (DHCP). Once the address is assigned, use
DevConfig, PakBusGraph, Connect, or the CR1000KD Keyboard Display to look
in the CR1000 Status table to see the assigned IP address. This is shown under
the field name IPInfo.
8.6.3.12 DNS
The CR1000 provides a Domain Name Server (DNS) client that can query a DNS
server to determine if an IP address has been mapped to a hostname. If it has, then
the hostname can be used interchangeably with the IP address in some datalogger
instructions.
8.6.3.13 SMTP
Simple Mail Transfer Protocol (SMTP) is the standard for e-mail transmissions.
The CR1000 can be programmed to send e-mail messages on a regular schedule
or based on the occurrence of an event.
8.6.3.14 Web API
The CR1000 web API (Application Programming Interface) is a series of URL (p.
532)
commands that manage CR1000 resources. The API facilitates the following
functions:
