  • Page 5: Introduction

    1. Introduction The I-7000 series is a family of network data acquisition and control modules, providing analog-to-digital, digital-to-analog, digital input/output, timer/counter and other functions. The modules can be remotely controlled using a set of commands, which we call the DCON protocol. Communication between the module and the host is in ASCII format via an RS-485 bi- directional serial bus standard.

  • Page 20: M-7000 Notes

    1.10 M-7000 Notes The main difference between the I-7000 and M-7000 series is that the M-7000 series has additional support for the Modbus RTU communication protocol, which is the default protocol of the M-7000 series. The communication Baud Rates for the Modbus RTU protocol can be in the range of 1200 bps to 115200 bps.

  • Page 27: Dcon Protocol

    2. DCON Protocol All communication with I-7000 modules consists of commands generated by the host and responses transmitted by the I-7000 modules. Each module has a unique ID number that is used for addressing purposes and is stored in non- volatile memory.

    A. Appendix A.1 INIT Mode Each I-7000 and M-7000 module has a built-in EEPROM to store configuration information such as module address, type code, Baud Rate, etc. Occasionally, the configuration of a module may be forgotten and there are no visual indications of the configuration of the module.
  • Page 125 Originally, the INIT mode is accessed by connecting the INIT* terminal to the GND terminal. New I-7000 and M- 7000 modules have the INIT switch located on the rear side of the module to allow easier access to the INIT mode. For these modules, INIT mode is accessed by sliding the INIT switch to the Init position as shown below.

  • Page 130: Reset Status

    A.5 Reset Status The reset status of a module is set when the module is powered-on or when the module is reset by the module watchdog. It is cleared after the responding of the first $AA5 command. This can be used to check whether the module had been reset.

  • Page 131: Frequency Measurement

    A.6 Frequency Measurement Frequency is usually measured by one of the following two methods. 1. by counting number of signal pulses during a known time interval, gate time 2. by counting number of pulses of a reference clock during the signal period M-7084 uses the second method for the frequency measurement.
