  • Page 5: Introduction

    1. Introduction The PET-7H16M is an high speed data acquisition devices built-in a Ethernet communication port for data transfer over the network and it includes eight high speed 16-bit single-ended analog inputs (200 KHz sample and hold for 8 channels), 4-channel digital inputs and 4-channel digital outputs.

  • Page 6: Features

    1.1. Features The PET-7H16M series family offers the most comprehensive configuration to meet specific application requirements. The following list shows the features designed to simplify installation, configuration and application. Data transmission mode 1. Continuous transmission (Maximum sampling rate of 30 kHz per channel) After starting A/D acquisition, data is continuously transmitted to the Host PC.
  • Page 7 2. After collecting N data samples, the data is transferred to the Host PC (Maximum sampling rate of 200 kHz per channel) a. After starting A/D acquisition, the data will be temporarily stored in the memory on the PET-7H16M module, and wait until a command is received from the Host PC, before transferring the collected data to the Host PC.
  • Page 8 A/D trigger mode 1. Software A/D Data Acquisition mode The A/D acquisition parameters are configured via a command from the Host PC. The continuous A/D acquisition or the acquisition of N data samples begins after the command is triggered. 2. External Digital Signal Event Trigger mode The A/D acquisition parameters are configured via a command from the Host PC, and then triggered via an external electrical signal.
  • Page 9 External Digital Signal Event Trigger Mode A/D acquisition is performed in external digital event trigger mode (triggering the electrical signal is the falling edge trigger). The maximum sampling rate per channel is 200 kHz, and A/D acquisition of N data samples is performed. The acquisition mode can be categorized into two types.
  • Page 10 Delay-Trigger (acquisition of N data samples) The A/D acquisition of the N data samples is started once the programmed delay period from the trigger has elapsed. Analog Threshold Trigger Mode Analog threshold Trigger is triggered when the voltage signal of the specified analog input channel is higher or lower than a certain voltage setting.

    Appendix 1A. What is Modbus TCP/IP? Modbus is a communication protocol that was developed by Modicon Inc. in 1979, and was originally designed for use with Modicon controllers. Detailed information regarding the Modbus protocol can be found at: http://www.modbus.org. The different versions of the Modbus protocol used today include Modbus RTU, which is based on serial communication interfaces such as RS-485 and RS-232, Modbus ASCII and Modbus TCP, which uses the Modbus RTU protocol embedded into TCP packets.

    A.1. Net ID (Station Number) The first byte in the frame structure of a Modbus RTU query is the receiver’s address. Availed address is in the range of 0 to 247. Address 0 is used for general broadcast, while addresses 1 to 247 are given to individual Modbus devices.

    A.3. Data Field Data is transmitted in 8-, 16- and 32-bit format. The data for 16-bit registers is transmitted in high-byte first format. For example: 0x0A0B ==> 0x0A, 0x0B. The data for 32-bit registers is transmitted as two 16-bit registers, and is low-word first. For example: 0x0A0B0C0D ==> 0x0C, 0x0D, 0x0A, 0x0B.
