1. Introduction

The I-7088 has 8 PWM output channels and 8 counter inputs and can be used to develop powerful and cost effective analog control systems. PWM (Pulse Width Modulation) is a powerful technique for controlling analog circuits that uses digital outputs to generate a waveform with a variable Duty Cycle (the fraction of time that a system is in an "active" state) and frequency to control analog circuits, and can be used to control the position/speed of motors, control the brightness of lamps, or control the speed of fans, etc.

The I-7088 will also automatically save the counter value to EEPROM if the power supply is interrupted or lost. Refer to Section

1.7 for details.

Features

 Automatic hardware generation of PWM outputs without the need

for software intervention.

 1Hz ~ 500KHz PWM output frequency with 0.1%~99.9% duty

cycle (Refer to Section 4.2).

 Software and hardware trigger mode for PWM output.  Individual and synchronous PWM output. By using software

trigger mode, you can set the configuration for all PWM channels then trigger them either individually or all at the same time.

 Burst mode PWM operation for standby.  DI channel can be configured as either a simple digital input

channel or a hardware trigger source for the PWM output.

2. DCON Protocol

All communication with I-7000 modules consists of commands generated by the host and responses transmitted by the I-7000 module. Each module has a unique ID number that is used for addressing purposes and is stored in non-volatile memory. The ID is 01 by default and can be changed using a user command. All commands sent to a module contain the ID address, meaning that only the addressed module will respond. The only exception to this is command ~** (Section 2.49), which is sent to all modules, but, in this case, the modules do not reply to the command.

Command Format:

Leading

Character

Module

Address

Command [CHKSUM] CR

Response Format:

Address

Data [CHKSUM] CR

CHKSUM A 2-character checksum that is present when the

checksum setting is enabled. See Sections 1.7 and 2.1 for details.

CR The End of command character, carriage return (0x0D)

I-7088 and M-7088 User Manual, Rev: A1.2 7MH-026-A12

Checksum Calculation:

Calculate the ASCII code sum of all the characters in the command/response string, except for the carriage return character (CR).

The checksum is equal to the sum masked by 0ffh.

Example:

Command string: $012(CR) The sum of the string = “$”+”0”+”1”+”2” = 24h+30h+31h+32h = B7h Therefore the checksum is B7h, and so CHKSUM = “B7” The command string with the checksum = $012B7(CR)

Response string: !01200600(CR) The sum of the string = “!”+”0”+”1”+”2”+”0”+”0”+”6”+”0”+”0” =

21h+30h+31h+32h+30h+30h+36h+30h+30h = 1AAh Therefore the checksum is AAh, and so CHKSUM = “AA” The response string with the checksum = !01200600AA(CR)

Note:

All characters should be in upper case.

Sets the status of the hardware trigger for PWM channel 0 to trigger stop and returns a valid response. When the rising edge of the DI is received, the status of the PWM will be set to trigger stop.

Command:

$01C1T0

Response:

!010

Sets the status of the hardware trigger for PWM channel 1 to disabled and returns a valid response. The PWM channel 1will not be affected when the rising edge of the DI is received.
