TestEquity Ethernet Interface for Environmental ChambersTestEquity Model 1056 Ethernet Interface Converter is a specialized Ethernet to Serial Interface that provides Modbus RTU packet communication to adapt the F4 or F4T Controller used on TestEquity chambers to a network. The converter lets you send simple ASCII read-write messages over the network to control and query the chamber's controller. The converter does all of the Modbus RTU packet formatting. An internal webserver provides a web page to read and control the chamber's set points and event outputs. The converter is packaged in a small minibox case. It can be used with any TestEquity chamber by plugging the converter cable into the chamber's serial interface connector. The TestEquity Model 1056 is based on an ICS Electronics 9099 Ethernet-to-Modbus Interface which has been customized to ensure compatibility with all models of TestEquity Chambers. It is 100% compatible with programs that were written for TestEqutiy Model 1055 (ICS 8099) Ethernet-to-Modbus Converter.

Internal Webserver
An internal webserver provides web pages for setpoint entry and readback, readback of actual chamber temperature and humidity, and Event Output setting/readback. Webserver pages for the F4T controllers add the ability to set manual ramp rate parameters.

Why use the Ethernet Converter when the F4T Controller has an Ethernet Interface?
The native F4T Ethernet Interface uses the Modbus TCP protocol. The 1056 Ethernet Interface Converter converts the controller's RS-232 Modbus interface to Ethernet. The converter takes care of the Modbus packet formatting so the command structure is simplified. The most compelling reason why you would want to use 1056 Ethernet Interface Converter instead of the F4T's native Ethernet interface is if you wanted to program using simple ASCII commands instead of Modbus packets. Note that Watlow Composer software will only work with the native F4T Ethernet interface.

Easy Programmability
The converter and chamber appear as a virtual instrument to the application and are easily controlled by the different programming techniques that are in common use with today's Test and Measurement systems.

If you program with LabVIEW, National Instruments' VISA library recognizes VXI-11.3 instruments like the converter as a TCP/IP resource. NI's Measurement and Automation Explorer finds and communicates with the converter as with any other VXI-11.3 compliant device. If you include the converter in a LXI system, the converter and its chamber will appear as an LXI compatible instrument and can be found with the VXI-11 Discovery procedure.

If you program with VEE, Keysight's (Agilent) IO Library treats the converter as any other LAN instrument and makes it available to your program. If you are a Visual Basic or C/C++ programmer, you can write your program to make calls to any VXI-11 compatible VISA library. You can also write your program using a raw socket connection to the converter. If you use Linux or any flavor of UNIX such as SunOS, IBM-AIX, HP-UX, or Apple's OS X, you can communicate with the 9099 through RPC over TCP/IP.

The user sends commands to the converter that sets the Modbus device address, specifies the register to be read or written to and the data value. The converter converts these commands into the Modbus packet format, adds the CRC checksum and transmits the messages to the F4, F4T, or EZ-Zone controller in the chamber. Received packets are checked and the responses to queries are returned to the network client. The converter command syntax includes an optional question mark to enable automatic response reading by included VXI-11 Keyboard Control program and other smart programs. Modbus communication faults, exception messages and other errors are reported to the user through a Modbus error register in the converter's 488.2 Status Structure. The user can set up the 8099's IEEE-488.2 Status Reporting Structure to generate a Service Request (similar to a GPIB SRQ) on an error or simply read the Modbus Error register if a problem occurs.

VXI-11.3 Operation
VXI-11 is a Ethernet instrument control protocol developed by the VISA committee when they established the VXI and VISA standards. VXI-11 provides GPIB like control of Ethernet instruments using RPC on TCP/IP. VXI-11 is a packet protocol designed to give the user error free communication with the instrument. Every VXI-11 command receives a response packet with command status information and the appropriate response data. The converter has an expanded IEEE-488.2 Status Reporting Structure that includes a register for reporting Modbus communication faults. The converter's Status Reporting Structure can be used to generate Service Requests using a Reverse Interrupt channel when an error occurs Alternately, the user can periodically query the Modbus Error and other register to check for command and communication errors.

Raw Socket Operation
The converter accepts telnet compatible, raw socket communication so that a non-VXI-11 user can send simple read-write messages over the network to control and query the chamber controller. This makes it easy to communicate with the converter without a VISA library. Reverse channel notification of an error is not possible with the raw socket protocol..

NOTE: TestEquity 1055 Ethernet Interface Converter is NOT compatible with Watlow's WatView or Composer software.
