Yokogawa SB301 Module

Yokogawa SB301 New And Original Module Japan

Overview

The CS3000 software operates as a Windows 3.1 application. It cannot preempt other applications or functions in Windows and, therefore, cannot guarantee a response time to user input actions. Using other applications while controlling a drive with the CS3000 software can tie up PC resources and cause drive commands to be delayed. To prevent drive commands (run, stop, and jog) from unexpectedly executing, the CS3000 software specifies a time-out period (approximately 2 seconds) when it establishes a link with the drive. While the link is established, the CS3000 software sends messages to the drive to validate the link. If a message fails to reach the drive within the time-out period because program execution has been delayed, the drive invalidates the link. If the link becomes invalid, the drive does not accept drive commands. If the drive was running, it stops, and a serial fault is generated. 

Before a drive control command is sent to the drive, the drive’s status is checked to validate the link. If communication between the CS3000 software and the drive have been interrupted and you have selected a drive command, the command is not sent and a message is displayed.

The time-out period is also used by the Parameter Monitor and Download functions, both of which could be running while the Drive Control Window is open. If the link becomes invalid while these functions are running, a message will be displayed in the Drive Control window before the link is re-established. When you select the Download command while the Drive Control window is open, you cannot execute drive command controls until the download is complete.
