Chapter 1 Product Introduction

(7) Task
You can assign 283 tasks at most to a program. Among these tasks, 32 are cyclic, 32 are I/O
interrupts, 4 are timer interrupts, two are communication interrupts, one is an external 24 V low-
voltage interrupt, and 212 are user-defined tasks.
You can enable and disable a task when running a program by using the TKON and TKOFF
instructions.
(8) Increasing hardware configuration efficiency through a USB cable and ISPSoft
The AS Series CPU module provides a standard USB 2.0 interface. USB 2.0 increases the data
transfer rate and decreases the time it takes to download the program, monitor the program, and
configure the hardware. You do not need to buy a special communication cable for the CPU module.
You can use a general USB cable to connect to the AS Series CPU module.
(9) Serial control interface with multiple functions
AS Series CPU modules provide two RS-485 serial control interfaces, COM1 and COM2, which can
be set as a either master or slave.
You use the communication cards to work with two extension serial communication ports and to set
the port as a master or slave.
