Operating Environment

Hardware Environment

  • CPU module:
ioPAC 8500-9-RJ45-IEC-T
  • Slot 1:
85M-1602-T
  • Slot 2:
85M-2600-T

Software Environment

  • Programming Tool:
ISaGRAF 6.3
  • Configuration Tool:
Moxa RTUxpress 1.1

Config Setting

Config file: ioPAC8500_iec_di.rtu

Step by Step

Initialization

  1. Import config file onto ioPAC
  2. Open IEC project via ISaGRAF
  3. Build -> Build Solution
  4. Import IEC porject onto ioPAC

Step 1

Prog1 check the DI0 and DI1 status and doing the OR operation, the boolean result will set to DO0.

Step 2

Prog2 detect DI2 status and then set to DO1 channel to start or stop PWM.

Step 3

Prog3 detect DI3 counter value, if its value > 10, then set DO2 ouput PWM 5 times.
