  • Page 4: Chapter1. Introduction

    Chapter1. Introduction 1. The 87K4/5/8/9 I/O Expansion unit is a plastic housing unit that provides one set power unit (10 V ~ 30 V DC) and one RS-485 interface and can be shared by those 87K I/O modules which are inserted into this I/O Expansion unit. This character can save time on wiring for power and RS-485 interface between 87K I/O modules.

  • Page 7 2.3 The INIT on the 87K4/5/8/9 I/O Expansion unit When we need to change communication parameters ( baudrate 、checksum and protocol etc ) on the module,INIT* pin need connects to GND on this module .The INIT* pins of Slot0 to Slot7 are located at the right edge of i-87K I/O Expansion. 2.3.1 The INIT at the backplane When power on i-87K I/O Expansion, only one INIT*-Switch can be set to ON Note 1:...
  • Page 8 The Slot location (index of Slot) is not related to the Net Address of I/O modules, it Note 3: only indicates the relative position of module on i-87K I/O Expansion unit. 2.3.2 The INIT* of i-87K High Profile I/O module between new and old backplane Some of the I-87K High Profile series I/O modules have INIT Jumper on module itself.
  • Page 9 And there are new i-87K I/O Expansion unit now. The only difference between new and old i-87K I/O Expansion unit is that It must put the INIT jumper at “INIT” position, if want to connect INIT* to GND, if i-87K high profile I/O with INIT Jumper plug in old i-87K I/O Expansion unit.

    Chapter3. Setup the Expansion unit and I/O modules. The first thing is to make sure the I/O Expansion unit is correctly wired, the basic wiring includes power supplier and communicate interface. 3.1 Power Supplier: Please refer to: http://www.icpdas.com/products/Accessories/power_supply/power_list.htm 1. The power supply must be DC power between +10V to +30V. 2.

  • Page 11: Rs-485 Converter

    3.2 RS-485 Converter: 87K4/5/8/9 I/O Expansion unit supports only i-87K and M-87K I/O modules. It does not support i-8K series I/O module. The only communication interface of 87K4/5/8/9 I/O Expansion unit is its RS-485 port. So, it often needs a RS-232 to RS-485 converter such as 7520 to converter the RS-232 signal to RS-485.

  • Page 17: Chapter4. Configure The I/O Modules With Dcon Utility

    Chapter4. Configure the I/O modules with DCON Utility. 4.1 Search 87K I/O with DCON Utility: DCON Utility is a program based on Serial interface I/O, it can search DCON Protocol and Modbus RTU Protocol modules and support checksum disable and enable. 4.1.1 COM Port and Searching Conditions: Step 1: Choose the COM port and select the searching parameters.
  • Page 18 4.1.2 Searching Principles: one. If there are several I/O modules with unknown Search and configure the I/O one by Net Address, Baud rate, Checksum and Protocol, they have to be searched and configured one by one. If failed to find the I/O module, it is better to Power on the I/O module with INIT* pin connects to the GND to get the I/O module’s initial communication settings.

  • Page 19: Search Result

    4.2 Search Result: When use DCON Utility to search 87K4/5/8/9 I/O Expansion unit and the 87K I/O modules, only 87K I/O modules can be found. 4.3 To Configure i-87K I/O modules: There are DCON Protocol and Modbus Protocol I/O module, for most general settings, they need to choose the wanted property and click setting to make it effect.
  • Page 20 There are some types of INIT* and they are at different position. i-87K4, i-87K8 I/O Expansion unit: The INIT* pins of Slot0 to Slot7 are located at the right edge of i-87K I/O Expansion. i-87K5, i-87K9 I/O Expansion unit: The INIT* pins of Slot0 to Slot7 are located at the right edge of i-87K I/O Expansion. But the INIT* pins of slot4 for 87K5 and slot8 for 87K9 are located at the first slot of Expansion unit.

    Appendix B: Frame Ground Electronic circuits are constantly vulnerable to Electro-Static Discharge (ESD), which become worse in a continental climate area. Some I-7000 ,M-7000 and I-8000 series modules feature a new design for the frame ground, which provides a path for bypassing ESD, allowing enhanced static protection (ESD) capability and ensures that the module is more reliable.
