How RS232 can be used to stop the machine

Dear All

 

I have question related to RS232

 

I have a machine that can be used to measure a pressure. The problem is that, this machine has a capacity which must not be exceeded.

I heard that RS232 can be used to stop the machine automaticly after it reach certain value.

Does anyone has an idea how to stop the machine using RS232?

 

Description of the machine:

1)WF10056 tritech 50

2)Digital

3)Computer functions with ASCII command

stop 0

up 1

down 2

fast up 3

fast down 4

new speed 7

 

Dasylab description:

Dasylab 5.02.20

basic version

dll driver v4.4

virtual driver 3.00

You will need to upgrade to Version 12 full because it would add actions modules and it wouyld be easyer to support you.

 

In any case, you would use a trigger module to detect a max value, when there is a triggering event, you will add an action that will sent the stop command to the RS232 output module

You may be able to use the RS232 with control inputs to send fixed commands, and avoid the Action module.
However, DASYLab 5.0.2 is over 15 years old, and never supported Windows XP. It's almost impossible for us to remember V5, much less provide active support for it.

Re: How RS232 can be used to stop the machine

Dear All

 

If I change dasylab into a newer version, will there be any incompatibility issue with the data logger?

Or the data logger has no compatibility issue with any dasylab or windows version that I use?

I use windows 95 right now

 

If I want to use action trigger module, should I use RS232 Input or RS232 Output?I'm a bit confused with this two module

Re: How RS232 can be used to stop the machine

What is the datalogger? the serial port device? If so, there should be no problem. 

 

Windows 95 is an unsafe and unsecure operating system. 

 

For commands to the device, not data request strings, use the RS232 OUTPUT. 

 

For commands to the device that request data, use the RS232 INPUT.

 

You've described a task that you will use the RS232 OUTPUT module, in Command mode (not data).

 

I no longer have V5 installed, so I cannot comment on the features or the settings for this module. My older Win95/98 computers have all failed.
